This document provides an overview of chapters 16 & 17 which cover the evolution of populations, the history of life, and key figures and concepts in evolutionary theory. It discusses how genes make evolution possible through genetic variation from mutations and gene recombination. Natural selection and genetic drift are described as causes of a population's gene pool changing over time, which can lead to the formation of new species through reproductive isolation. Fossils are examined as evidence for evolution and mass extinctions. Patterns in the fossil record show most species have become extinct, fossils are found in a particular order, and organisms have changed over time. Evolution occurs through both gradualism and punctuated equilibrium.

In line with generally accepted theories of evolution, Dinosaur extinction is currently believed to be due to climate change due to various causes. However this is not correct, being inconsistent with known facts. There are only two possibilities. Either Dinosaurs evolved to their extinction or evolved to some other phyletic lines or species with which ancestor – descendent relationship can’t be presently demonstrated.
Author: Dr Mahesh C. Jain is a practicing medical doctor and has written the book “Encounter of Science with Philosophy – A synthetic view”. The book begins with first chapter devoted to scientifically valid concept of God and then explains cosmic phenomena right from origin of nature and universe up to origin of life and evolution of man. The book includes several chapters devoted to auxiliary concepts and social sciences as corollaries to the concept of God. This is the only book which deals with origin of nature and universe from null or Zero or nothing. Chapter 30 of the book is about Evolution of Life wherein author has worked out a new theory about evolution of life.

Darwinism and natural selection 7th zol.pptximranrohi56
Darwin's three main principles of natural selection state that, in order for the process to occur, most characteristics in the population must be inherited, more offspring must be produced than can survive, and the fittest offspring must be more likely to survive and reproduce.In the mid-19th century, a man came up with a very powerful idea, the idea that species could change. Today, all the time, we hear about animals adapting, endangered species going extinct, viruses mutating. But in the 1800s, people conceptualized a much more static world. One man looked past all that. His name was Charles Darwin.
Darwin called his idea the theory of natural selection. Natural selection is defined as a natural process that results in the survival and reproduction of organisms with genetic traits best suited to their environment. A shorter (but no less accurate) definition might be "survival of the fittest." Within any population, the fittest individuals, or the ones who fit the environment best, usually survive and reproduce, passing on their genetic traits to future generations.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Chapter 16 & 17 Evolution of Populations and The History of Life
1. Chapters 16 & 17
Evolution of Populations and
The History of Life
2. Evolution of Populations
• EQ: How can populations evolve to form
new species?
– How do genes make evolution possible?
– What causes a population’s gene pool to
change?
-- How do new species form?
5. Theory of Acquired Characteristics
• Theory that organisms’ selective use and disuse
of organs led to acquiring or losing certain traits
in their lifetime.
• These traits could then be passed on to their
offspring
• Ex) giraffe stretching to get leaves = neck gets
longer over time….pass longer neck on to
offspring (incorrect)
7. Darwin
On what concept was this work based?
Observations
• Members of a population often vary greatly in
their triats
• Traits are inherited from parents to offspring
• All species are capable of producing more
offspring that their environment can support
8. Darwin
On what concept was this work based?
Inferences
• Individuals whose inherited traits give
them a higher probability of surviving and
reproducing in a given environment tend
to leave more offspring than other
individuals
• This unequal ability of individuals to
survive and reproduce will lead to the
accumulation of favorable traits in the
population over generations.
9. Genetics & Evolution
• Scientists discovered that heritable traits
are determined by DNA (genes on
chromosomes).
• Later they realized that changes in the
DNA (mutations) and gene recombination
through sexual reproduction results in
variations; thus, further relating Darwin
and Mendel’s original work.
10. Evolution acts on ______________________ not on individuals.
Example: Black lizards are able to absorb more heat on cold days.
The extra heat allows
them to move more quickly on cold days which makes
them better able to
avoid predators. The allele for black body would
increases an individuals
fitness and they would leave more offspring that other
lizards. The relative
frequency of the allele for black body could, therefore
increase.
12. Two main sources of
genetic variation
1. Mutations—change in genes (DNA
sequence) or chromosomes
2. Gene recombination—mixing of
genes that result from:
A. meiosis
B. sexual reproduction
27. Three types of reproductive
isolation
1. Behavioral isolation (sounds or display rituals)
2. Temporal isolation (nocturnal vs. diurnal)
3. Geographical isolation (separated by oceans or
mountain ranges)
If one of the Earth’s plates moves 1.9 cm a yr., in 1 million years it
would move 12 miles
29. Allopatric Speciation
Gr. other + fatherland
The formation of new
species in populations
that are geographically
isolated.
Ex: mountains, canyons,
or oceans
35. Courtship
Type of behavior in which an animal sends
out stimuli in order to attract a member of
the opposite sex.

http://www.pbs.org/wnet/nature/video/what-males-will-do-video-spidercourtship-dance/956/
36. Social Behavior
The interaction of members with their own
species in a way to increase the fitness of
all members.
Ex: packs, colonies, hives, troops
38. EQ: How do fossils help biologists
understand the history of life on Earth:
– How do scientists use fossils to study Earth’s
history?
– What are some patterns in which evolution
has occurred?
– How fast does evolution take place?
39. Earth’s Early Atmosphere
• Over time photosynthetic bacteria became
common in the sea which started adding
oxygen to the atmosphere
• Next, oxygen gas started accumulating in
the atmosphere which decreased the
hydrogen sulfide and methane and
eliminating most anaerobic organism but
increased aerobic organisms
40. • The ozone layer started to form to provide
protection from ultraviolet rays
• Some organisms evolved ways of using
oxygen for respiration and greater energy
production
• With more energy available, eukaryotes
evolved in the sea and then on land
• The eukaryotic cells aggregated into
multicellular organisms and the evolution
of the diversity of life was well on its way

**Mixtures of the organic compunds necessary
for life could have arisen from simpler
compounds on present on a primitive Earth.
**Found that life arose from non-life. Is this
true?
42. Fossil
• Preserved remains of ancient organisms
• http://www.neok12.com/php/watch.php?

45. 1. Most organisms that have
ever lived are now extinct
2. fossils occur in a particular
order in the rock layer
3. groups of organisms have
changed over time
52. What are some patterns
in which evolution has
occurred?
53. Mass Extinction
Many types of living things become extinct
in a short period of time
