Genetic mutations and recombination can create new allele forms of genes that may be better suited for the environment and increase the fitness of the organism. Natural selection acts on these genetic variations, promoting the survival and reproduction of individuals with genotypes best fitted to the environment, ultimately shaping the evolution of populations and species over generations.

Biology - Part D Regents Review - Relationships and Biodiversity
This lab uses 7 tests to determine the evolutionary relationships between plant samples X, Y, and Z and the known species Botana curus. The tests examine structural characteristics, pigmentation through paper chromatography, presence of the enzyme M, simulated gel electrophoresis of DNA, and translation of DNA into amino acid sequences to form proteins. Sample Z is found to be most closely related to B. curus based on sharing the most characteristics across the various tests. Genetic evidence from DNA is considered the strongest indicator of evolutionary relationships. Determining relatedness helps scientists understand biodiversity and how extinction of species can impact ecosystems.
ENV107 - Lecture 12
Biological diversity is shaped by biological evolution through processes like natural selection, genetic drift, migration, and geographic and reproductive isolation. Natural selection leads to increases in heritable traits that aid survival and reproduction. Genetic drift causes changes in gene frequencies by chance rather than selection. Geographic isolation occurs when populations become physically separated, and over time this can lead to reproductive isolation and speciation as the populations evolve independently. Extinction also influences biodiversity by removing species. Factors like habitat diversity, moderate disturbance, and evolution tend to increase diversity, while stress, limited resources, and extreme disturbance decrease it.
ENV 107 - Lecture 4
1) The lecture will cover the Facebook page link for the class, details about an upcoming quiz exam, Garrett Hardin's Tragedy of the Commons, the Precautionary Principle, and a video of President Obama's 2014 UN Climate Summit Speech.
2) Garrett Hardin's Tragedy of the Commons refers to how individuals acting in their own self-interest can deplete shared limited resources. Examples include overuse of public land and pollution. Solutions involve restricting access and creating incentives for responsible use.
3) The Precautionary Principle is a response to uncertainty about risks to health or the environment. It advocates taking action to avoid potential harm when scientific certainty about risks is lacking.
Charles darwin
Charles Darwin was an English naturalist born in 1809 who is best known for his theory of evolution by natural selection, as published in his 1859 book On the Origin of Species. Darwin observed that individuals within a species vary in how well they are adapted to their environment, with better adapted individuals more likely to survive and reproduce, passing on beneficial traits over generations through a process known as natural selection.
Evolution and natural selection 2015
The document provides background information on the key individuals and ideas that influenced Charles Darwin's theory of evolution by natural selection. It describes the contributions of thinkers like Lamarck, Malthus, Lyell, and others to early concepts of evolution and population growth. It then summarizes Darwin's voyage on the HMS Beagle where he made observations of species variation that helped form his ideas, and outlines his subsequent development of the theory of evolution by means of natural selection, which he published in On the Origin of Species in 1859.

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.
Mutation, Evolution, and Natural Selection
DNA mutations can cause changes in gene sequences over many generations, leading to evolution through natural selection. Mutations occur randomly during DNA replication and can be beneficial, harmful, or neutral. Charles Darwin observed through his voyage on the HMS Beagle that species adapt to their environments over time, with beneficial traits increasing an organism's chances of survival and reproduction.

1) Charles Darwin nasceu em 1809 na Inglaterra e tornou-se um naturalista famoso.
2) Durante 5 anos, Darwin participou de pesquisas nas Américas do Sul e Central, Austrália e Nova Zelândia.
3) Após a viagem, Darwin tentou descobrir a razão da diversidade de plantas e animais e escreveu "A Origem das Espécies" e "A Descendência do Homem", onde apresentou suas ideias sobre evolução.
Teoria del Darwinismo
Charles Darwin propuso la teoría de la evolución de las especies a través de la selección natural, la cual establece que las variaciones genéticas entre los individuos de una población determinan su probabilidad de supervivencia y reproducción. Su obra más conocida, El origen de las especies, presentó esta teoría en 1859 explicando que las especies se transforman gradualmente a lo largo del tiempo.
Speciation and Evolution
Describes and analyzes speciation, including the processes of adaptive change, adaptive radiation, phyletic gradualism, and punctuated equilibrium
Speciation powerpoint
This document discusses evolution and speciation. It begins by outlining the classification system for humans, then discusses what defines a species. A species is defined as a group that can interbreed and produce fertile offspring, but there are exceptions. Speciation occurs through both geographic isolation (allopatric) and changes within populations (sympatric). Isolating mechanisms, genetic drift, migration, and chance events can all contribute to the formation of new species. Speciation rates vary widely and mass extinctions have occurred periodically throughout history.
Theory of Evolution
Darwin proposed the theory of evolution by natural selection, with four main ideas: 1) Common descent, that all organisms are related through descent from a shared ancestor, 2) Gradualism, that new species arise gradually through accumulation of adaptations, 3) Multiplication of species, whereby gradual changes lead to diversification, and 4) Natural selection, the mechanism by which organisms better adapted to their environment are more likely to survive and produce offspring.
Charles Darwin
1) Charles Darwin was a British naturalist born in 1809 who studied medicine and divinity before joining a scientific expedition on the HMS Beagle as their geologist from 1831-1836.
2) While traveling on the Beagle, Darwin was influenced by the ideas of Charles Lyell and observed unique species of finches on the Galapagos Islands, sparking his theory of evolution by natural selection.
3) After corresponding with Alfred Russel Wallace, Darwin published On the Origin of Species in 1859, introducing his theory that organisms change over generations through a process of natural selection, survival of the fittest, and gradual speciation from common ancestors.
Darwin’s theory of evolution
Darwin proposed four main ideas about evolution: 1) Common descent - all organisms are related through descent from a common ancestor; 2) Gradualism - new species arise gradually through accumulation of small adaptations over time; 3) Multiplication of species - populations tend to increase in size, leading to new species; 4) Natural selection - individuals with traits better suited to the environment will leave more offspring, driving evolution.
Origin of language
The document discusses several theories about the origins of human language. It begins by outlining two divine source theories - that language originated from God or divine beings. It then examines physical adaptation theories which argue that the evolution of certain human physical traits, like bipedalism and advanced vocal tracts, enabled the development of speech. The document also explores natural sound theories, which propose that early words imitated environmental sounds or emotional cries. It questions whether these could have generated full languages.
