Charles Darwin developed the theory of evolution through his observations on the Galapagos Islands and later research. He noticed that different species of finches on different islands had developed variations in beak size and shape that correlated with their availability of food sources, demonstrating adaptive evolution through natural selection. Later studies also showed examples of evolution through natural selection, such as peppered moths changing in coloration to better camouflage against tree bark during the Industrial Revolution. Darwin's work established evolution as a key explanation for diversity of life on Earth.

This document discusses Darwin's theory of evolution by natural selection. It explains that Darwin observed greater diversity of species during his travels than in his native country, which led him to propose that all species gradually change over time and descend with modification from other species. Modern understandings incorporate genetics, showing how mutations in DNA can provide variation for natural selection to act upon. Fossil evidence also documents how life has changed over time.
ENV107 - Lecture 11
This document provides an overview of biological diversity and related topics. It defines biological diversity as the variety of life forms in an area, often expressed as the number of species or genetic types. Biogeography is described as the geographic distribution of species. The document discusses why people value biodiversity and lists some of the main reasons. It also outlines some key aspects of biological diversity including genetic diversity and habitat diversity. Additionally, it provides estimates for the total number of species on Earth and notes that the exact number is unknown. The document includes examples of species richness in Bangladesh and describes the main processes involved in biological evolution, focusing on mutation.
Micro evolution,macro evolution or mega evolution ppt
Microevolution involves small changes within a species that can create new subspecies through natural selection, mutation, recombination and gene flow. Macroevolution occurs at higher taxonomic levels and creates new families, orders and genera through population fragmentation and genetic divergence, accumulating many microevolutionary changes. Megaevolution is the origin of major biological groups like amphibians from fish and reptiles from amphibians through rare parental simple adaptations that give rise to new levels of biological organization.
Unit 11 evolution of populations
Paleontology, genetics, and molecular evidence all support evolution through fossils, DNA and protein comparisons. Genetic variation within populations increases the chances of survival and comes from mutation, recombination and hybridization. Natural selection can act on populations in three ways - directional selection favors one phenotype extreme, stabilizing selection favors intermediate phenotypes, and disruptive selection favors both extremes.

Drawins theory of evolution powerpoint
Darwin's theory of evolution proposed that all species evolved over time from common ancestors through a process of natural selection acting on hereditary variation in populations. His main ideas included common descent, whereby all organisms are related through descent from some unknown ancient ancestor; gradualism, where new species slowly accumulate adaptations to different environments over time; and natural selection, as the mechanism driving evolution by preferentially reproducing individuals with advantageous traits.

Over 10 weeks, the author observed and documented the ecology of their 1 cubic meter garden pond site. They took photos each week and annotated factors like organisms present. Both bacteria and archaea were found in the pond, with some able to tolerate extreme temperatures. The physiological processes of earthworms in the location were described, including their digestive and reproductive systems. A concept map was included summarizing the biotic and abiotic factors in the garden pond ecology over the 10 week period, including producers, consumers, decomposers, and chemical/physical factors.
Evolution
- Modern evolutionary theory holds that evolution occurs gradually within populations as individuals vary and natural selection acts upon these heritable variations. While Darwin's theory of evolution is widely accepted, he did not explain the mechanisms of variation.
- Hugo de Vries proposed the "mutation theory" in the early 1900s, observing large sudden variations in primrose plants that bred true. He believed new species evolved via large mutations.
- Populations, not individuals, evolve as gene pools change over generations through natural selection acting on heritable genetic variations introduced by mutations and sexual reproduction.
Lamarckism and neolamarkism
This document discusses Lamarckism and Neo-Lamarckism. It provides examples of experiments that support Lamarck's theory that acquired characteristics can be inherited, such as stickleback fish developing bony plates in saltwater and mice developing longer limbs when raised at high temperatures. However, it also notes criticisms of Lamarckism, such as some organs like the heart not changing in size despite constant use. Neo-Lamarckism is presented as a modification that does not involve an internal drive for change and only heritable variations that affect germ cells can be passed on.
Natural selection
Natural selection is a process by which beneficial traits become more common in a population over generations. It occurs through adaptation as individuals with traits that increase reproductive success are more likely to pass on those traits. There are different types of natural selection including directional selection which favors extreme phenotypes, stabilizing selection which favors intermediate phenotypes, and diversifying selection which maintains diversity in heterogeneous environments. Reproductive success and fitness are measures of how likely an individual is to contribute offspring to the next generation and natural selection acts upon traits that increase these measures.
Ch 15 Evolution
The document discusses the theories of evolution proposed by Jean-Baptiste Lamarck and Charles Darwin. Lamarck believed that organisms could pass on characteristics they acquired during their lifetime to their offspring through inheritance. Darwin proposed his theory of natural selection, in which variation exists within populations and individuals with traits better suited to their environment are more likely to survive and pass on those traits, leading to evolution over time. While both recognized that species change over time, they disagreed on inheritance, with modern science supporting Darwin's theory based on genetics and fossil evidence.
Evolution by natural selection
This document discusses evolution by natural selection. It notes that members of a population vary in traits, traits are inherited from parents to offspring, and all species can produce offspring. However, if the environment lacks survival resources like food, some offspring will not survive. This leads to the conclusions that individuals with inherited traits better suited to the environment will have a higher probability of surviving and reproducing, passing on these favorable traits over generations. The document then defines natural selection as increasing adaptation over time by differential survival and reproduction of individuals with heritable traits. It also discusses speciation, or the origin of new species, and the mechanisms that can lead to reproductive isolation between populations.
Neo darwinism hassan
This document discusses the theory of Neo-Darwinism, which is a synthesis of Darwin's theory of natural selection and modern genetics. It describes key aspects of Neo-Darwinism, including genetic variation, mutations, natural selection, genetic drift, and isolation. Several scientists in the 20th century contributed to the development of the modern synthetic theory, including research on population genetics, genetics, and heredity. Examples are given of natural selection in industrial melanic moths and the development of antibiotic resistance in bacteria.
Unit 10 natural selection
The document discusses key concepts and evidence related to Darwin's theory of evolution by natural selection. It describes how Darwin observed adaptations in species on the Galapagos Islands and how this insight, combined with evidence from fossils, biogeography, embryology and anatomy, led him to propose natural selection as the mechanism of evolution. Natural selection acts on inherited variation in traits, with those conferring greater fitness being passed on to more offspring over generations of descent with modification.
Evidence of evolution
1. Artificial selection through experiments by biologists provides evidence of natural selection. The only difference is that humans rather than nature determine which individuals pass on their genes.
2. Direct observation of evolution over time has found directional selection leading to traits like darker pigmentation, larger brain size, faster enzymes, and more extensive root systems.
3. Patterns of adaptation like convergent and divergent evolution provide further evidence. Convergent evolution occurs when similar environments produce similar adaptations in different organisms, while divergent evolution produces different adaptations in closely related organisms facing different environments.
Evolution
This document discusses several key concepts and theories related to evolution:
1. It describes Lamarck's theory of evolution which proposed that acquired traits could be inherited. It notes this theory is no longer supported.
2. It summarizes Darwin's theory of evolution by natural selection, noting the key principles of overproduction, variation, adaptation, and natural selection.
3. It discusses Hugo de Vries' mutation theory which proposed evolution occurs through accumulation of mutations in genes.
4. It notes the modern synthesis combines Darwinian evolution through natural selection with Mendelian genetics.
Intraspecific variation
Intraspecific variation refers to differences that occur within a species. Variation can be caused by both genetic and environmental factors. Genetic factors include differences in alleles that cause phenotypic variations like eye color. Environmental factors influence phenotypes as well, such as how temperature affects the fur color of Himalayan rabbits. Often variation is a combination of both genetic and environmental influences, such as how genetics and nutrition interact to determine a person's height. Genetic variation within and between populations can be measured to understand intraspecific variation.
factors affecting allele frequencies
This document discusses factors that affect genetic variation and change in populations, including evolution, natural selection, mutations, migration, and genetic drift. It provides details on each factor and how they influence allele frequencies in a gene pool over multiple generations, leading to evolution and potentially new species. Examples are given to illustrate concepts like founder effects and bottleneck effects on small populations.
Evolution powerpoint!
Charles Darwin developed the scientific theory of evolution by natural selection to explain how species change over time through descent with modification from common ancestors. His theory states that genetic variation within species leads to different traits, which are acted on by environmental pressures like competition for resources and predation. Traits that increase survival and reproduction become more common in populations over many generations, resulting in evolution of new species. Darwin provided extensive evidence from biogeography, fossils, embryology and comparative anatomy to support his theory.

The document summarizes a study on the breeding behaviors of Ebony Jewelwing dragonflies in four zones along a 375m stretch of South Brook in Bridgewater, MA. Data was collected weekly from May to August 2015 on behaviors like guarding and ovipositing. A strong positive correlation was found between plant density and total observed behaviors and female ovipositing. No correlations were found between stream discharge and behaviors. Temperature and light sensors recorded data, with zones of higher temperature tending to have more behaviors, but light levels did not correlate with behaviors between zones except during peak periods. The study aimed to understand how environmental factors like temperature and flow influence breeding activities in this local dragonfly population.
Theories of evolution
Lamarckism and Darwinism are two theories of evolution. Lamarckism, proposed by Jean-Baptiste Lamarck in 1809, suggests that organisms can pass on traits acquired during their lifetime to their offspring. Darwinism, proposed by Charles Darwin in 1859, proposes that evolution occurs through natural selection, where organisms better adapted to their environment are more likely to survive and pass on their traits. Key aspects of Darwinism include variation between individuals, the struggle for existence due to limited resources, and survival of the fittest individuals who pass on adaptive variations. Over many generations, these variations accumulate and can lead to the formation of new species.
trands and rates of evolution
The document discusses several trends and rates of evolution, including Dollo's law of irreversibility, Cope's law of body size increase over generations, and Gause's exclusion principle of ecological niche overlap. It also covers Bergman's rule relating body size and temperature, techniques for examining evolutionary rates like DNA analysis, and the hypotheses of gradual vs punctuated change to explain rates of evolution. Resources on these topics are listed at the end.
Modern theories of evolution
Modern evolutionary theory, also known as neo-Darwinism, explains how evolution occurs through natural selection acting on genetic variations in populations over multiple generations. Natural selection favors individuals whose genetic variations increase their chance of survival and reproduction, causing gene frequencies in populations to change over time. With enough genetic change over long periods, new species may form. Evidence for evolution comes from fossils that can be carbon dated, showing lineages of organisms changing over time, as well as similarities in cell biology and genetics between related species.
What influences natural selection
This document discusses factors that influence natural selection:
1. Genetic variety within species, brought about by mutations and genetic recombination, allows for variation on which natural selection can act.
2. Gene expression influences how genes determine traits.
3. Excess reproduction, the ability of most species to produce more offspring than can survive, means individuals must compete for limited resources. Together, genetic variety, gene expression, and excess reproduction exert influence on the process of natural selection.

The Consumer Goods Forum (CGF) works to phase out HFC refrigerants and replace them with more sustainable natural refrigerant alternatives. CGF members have installed natural refrigerant systems in over 10,000 stores globally. While natural refrigerants face challenges in terms of cost and viability in hot climates, case studies show they can be cost-effective compared to HFCs over the long-term due to lower operational costs. CGF is working with members and stakeholders to share best practices and further the transition away from HFCs, which if phased out could significantly reduce global warming.

Theoryofevolution 110815170612-phpapp01
The document provides an overview of the theory of evolution. It begins by defining evolution as the gradual change in organisms over generations through natural selection. It discusses evidence that supports evolution such as structural adaptations, mimicry, fossils, and similarities in early embryo development across species. It then explains key aspects of the theory including Charles Darwin's contributions and voyages, his observations that led to his theory, and mechanisms of evolution like natural selection and speciation. The summary concludes by noting that Darwin published his theory in On the Origin of Species, which challenged existing beliefs by proposing gradual evolution of species from common ancestors through natural selection.
Biology - Chp 16 - Evolution Of Populations - Powerpoint
1) The Grants studied Darwin's finches on the Galapagos Islands and found evidence supporting Darwin's theory of natural selection by observing variation in heritable beak traits and how this variation influenced bird survival rates during drought conditions.
2) Speciation of Darwin's finches occurred through geographic isolation of populations on different islands, genetic changes in isolated groups, and reproductive isolation once populations were able to interbreed upon secondary contact.
3) While the Grants did not directly observe the formation of new species, their work provided strong empirical data for natural selection and inspired continued research on evolution in nature.
evolution__biodiversity_ppoint.ppt
Evolution and biodiversity occurred over billions of years as follows:
- Chemical evolution began 4.7-4.8 billion years ago as life evolved on Earth. Biological evolution began around 2.3-2.5 billion years ago.
- Species evolve over time through genetic mutations and natural selection, which can lead to microevolution within a population or macroevolution where new species are formed.
- Biodiversity has increased through speciation as new species evolve but has also decreased due to extinction, both through natural causes and more recently by human impacts threatening many species.

- Biodiversity has increased through speciation as new species evolve but has also decreased during mass extinction events, such as when the dinosaurs went extinct 65 million years ago. However, adaptive radiations then led to explosions of new species.
Unit 5 evolution by natural selection
1) The document summarizes key concepts from Chapter 22 of Campbell and Reece (2010) on evolution by natural selection, including different types of evidence that support evolution such as fossils, homology, biogeography, and genetics.
2) It discusses Darwin's voyage on the Beagle where he observed adaptations of plants and animals in diverse environments and was influenced by observations of finches in the Galapagos Islands.
3) It describes Darwin's theory of natural selection where individuals with heritable traits that increase survival and reproduction will pass those traits on to more offspring over generations, leading to adaptation and speciation over time.
Unit 5 evolution by natural selection
1) The document discusses evidence for evolution including fossil records, homology, biogeography, and genetics. Fossil records show extinction, origins of new groups, and changes over time.
2) Homology provides evidence of common ancestry through similar structures in different species. Biogeography, such as Darwin's observations of island species, also supports evolution.
3) Darwin developed the theory of evolution by natural selection, which proposes that genetic variations arise by mutation and populations evolve through natural selection of inheritable traits that increase survival and reproduction.
Chapter 14 Darwin and Evolution
Darwin proposed that evolution occurs through natural selection, where organisms better adapted to their environment are more likely to survive and pass on their traits. He reached this conclusion based on observations from his voyage on the HMS Beagle of fossils, biogeography of the Galapagos Islands, and how species were suited to their environments. Evidence from fossils, anatomical similarities between species, molecular biology, and biogeography provide strong support for Darwin's theory of evolution by natural selection.
Evolution
1. Darwin developed his theory of evolution by natural selection after observing variation between species in the Galapagos Islands and after reading Malthus' work on population growth.
2. His theory proposed that species evolve over generations through natural selection of inheritable traits that aid survival and reproduction in the local environment.
3. Evidence that supported Darwin's theory included the fossil record, observations of artificial selection influencing domesticated species, and similarities found across all life when comparing genetic codes and cellular functions.
Speciation and-evolution-1204077108861903-5
Speciation occurs through two main processes - cladogenesis, where one species splits into two, and anagenesis, where an ancestral species is replaced by a descendant over time. New species arise through geographical or reproductive isolation of populations. Adaptive radiation is the evolution and diversification of species into new niches, and can be generalized or specialized. Evidence for evolution includes fossil records, extinct species, and ancient hominins, while creationism has been disproven.
Speciation and-evolution-
Speciation occurs through two main processes: cladogenesis, where one species splits into two, and anagenesis, where a new species replaces the ancestral one. New species arise through geographical isolation or reproductive isolation. Speciation can be allopatric, with populations separated geographically, or sympatric, with reproductive isolation mechanisms allowing speciation in the same region. Adaptive radiation is the evolution and diversification of species into new niches, and can be generalized or specialized. Evolution occurs through both gradual processes like Darwinian gradualism as well as punctuated equilibrium, with rapid changes between long periods of stasis. Evidence from geology, fossils, and genetics overwhelmingly supports evolution rather than pseudoscientific ideas like creationism.
Theory Of Evolution of Natural Selection by DARWIN
Charles Darwin developed the theory of evolution by natural selection. As a naturalist aboard the HMS Beagle, Darwin made observations and collected evidence that led him to propose that life evolves over generations through a process of natural selection, where organisms better adapted to their environment tend to survive and pass on their traits. Darwin believed that all species on Earth descended with modification from common ancestors over long periods of time. His theory challenged religious orthodoxy and provided a naturalistic explanation for the diversity and complexity of life.
Reef ecosystems and their decline
Reef ecosystems have been in steady balance for millions of years but are now in decline due to climate change, bleaching, and overfishing. Climate change is stressing corals through warmer water temperatures, which causes them to lose their symbiotic algae and turn white. The oceans absorbing carbon dioxide from human activities is also making the water more acidic, inhibiting corals' ability to build skeletons. Overfishing disrupts the delicate food chain by removing key species. To remedy this, stronger fishing regulations and more protected areas are needed, while addressing the underlying causes of climate change.
2 Biological Change.ppt
The document discusses several key topics related to evolution:
1. It describes common descent and provides evidence from DNA, RNA, amino acid sequences, and fossils.
2. It discusses Charles Darwin's contributions including his voyage on the HMS Beagle and publishing On the Origin of Species in 1859 introducing natural selection.
3. It provides examples of adaptations through structures like camouflage and mimicry as well as physiological adaptations in bacteria that provide evidence of evolution.
Organism and Its Environment
This document discusses various concepts related to how organisms adapt to their environments, including adaptation, evolution, natural selection, ecological niches, and species interactions. It defines key terms like adaptation, evolution, Darwin's theory of evolution, mechanisms of evolution, ecological niche, niche types, speciation, extinction, and organism interactions. Examples are provided to illustrate concepts like natural selection, genetic drift, mutation, migration, microevolution vs macroevolution, fundamental vs realized niche, and speciation patterns. Factors that can influence speciation and extinction like continental drift, climate change, and catastrophic events are also outlined.
Oxytetracycline and thermal marking of alewife (Alosa pseudoharengus) otoliths
Presented by Steven Luell for his thesis defense at the University of New Hampshire in August 2016
Abstract:
Alewives (Alosa pseudoharengus) are anadromous clupeids native to the east coast of North America. With their population in decline, there is increasing interest in releasing hatchery-reared alewives for stock enhancement. As a result, techniques are needed to produce long-lasting marks to identify stocked fish. The objective of this investigation was to evaluate the efficacy of marking alewives using oxytetracycline immersion and thermal marking techniques. Oxytetracycline marking trials consisted of immersing alewife larvae in three concentrations of oxytetracycline (200, 400, and 600 mg/L) for two durations (4 and 6 hours). Sagittal otoliths were removed and examined for marks with a fluorescence microscope after 158, 232, and 350 DPH in October 2015, January 2016 and May 2016. Exposure to higher concentrations and longer durations in the immersion bath resulted in a higher percentage of fish with visible marks. Oxytetracycline marks were present on 100% of the otoliths sampled from the 6-hour immersion in 600 mg/L. Alewife larvae and juveniles were exposed to various temperature change regimes to produce thermal marks on the sagittal otoliths. All of the juveniles survived the thermal marking but the larvae experienced 100% mortality during the marking procedure. Otoliths were examined for thermal marks after 142, 271, and 349 DPH in October 2015, February 2016 and May 2016. Exposure to warm water temperatures for 24 hours created wider translucent increments between the opaque bands on the otoliths. There did not appear to be a difference in the lightness of the increments or darkness of the bands between the 25ºC:18ºC or 28ºC:16ºC treatments. The results of this study indicate that the optimal marking procedure for mass-marking alewives for stock enhancement is immersing larvae in 600 mg oxytetracycline/L for 6 hours.
THEORIES OF ORGANIC EVOLUTION NEO-DARWINISM.pdf
The document discusses several theories of organic evolution:
- Lamarckism proposed that evolution occurs through inheritance of acquired characteristics from parents' use or disuse of organs.
- Darwin's theory of natural selection proposed that evolution occurs through natural selection of beneficial inherited variations.
- Mutation theory proposed that mutations are the raw material for evolution and only useful mutations are selected by nature.
- Neo-Darwinism updated Darwin's theory, proposing that evolution occurs through differential reproduction and inheritance of genetic variations from the gene pool.
Evolution in a nutshell
This document summarizes key concepts of evolution including Lamarck's theory of acquired traits versus Darwin's theory of natural selection and survival of the fittest. It also discusses evidence that supports common ancestry, such as embryology, similar macromolecules, vestigial structures, biogeography, and homologous/analogous structures. Finally, it outlines different types of evolution like divergent, convergent, and phyletic and explains scientific classification from kingdom to species.
Evolution
The document summarizes key concepts in evolution including:
1. Early theories like abiogenesis, spontaneous generation, and Oparin-Haldane's chemical evolution hypothesis were disproven by experiments from Redi, Spallanzani, and Pasteur showing life only comes from life.
2. Miller-Urey experiment provided evidence that amino acids could form from simple inorganic molecules, supporting chemical evolution.
3. Darwin's theory of evolution by natural selection proposed that variation within species and inheritance of traits with differential survival and reproduction could account for evolution over generations.
4. Modern evolutionary synthesis combined genetics, population genetics, and paleontology showing microevolution accumulates over time to produce macroevolution
Phylogenetics: Evolution
This document discusses evidence that supports the theory of evolution through natural selection. It provides examples of homologous structures that indicate common ancestry, such as the bones in the human arm and horse leg. Modern examples, like the evolution of pesticide resistance in insects and antibiotic resistance in bacteria, illustrate evolution in action. The document also explains how the fossil record, analogous structures, vestigial structures, and comparisons of macromolecules across species serve as lines of evidence for evolution through natural selection over generations.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
