Genographic Project: [|Genetics Overview] HW: [|Homonid Project - On Becoming Human.doc] - Begin. Due Friday. || HW: [|Biogeography] module from Evolution 101. || Essential Questions: <**this person** is responsible to begin> > Charles Darwin (1809-1882), was a famous English naturalist who realised and presented compelling evidence that all species of life have evolved over time from common ancestors, through the process he called natural selection. He was born into a rich family, where he was wanted to study medicine, but he persists on being a naturalist even without working for a high raise due to the family's wealth. Darwin's revolutionary idea of natural selection and such were one of the first to go against the religious explanation of where God started all life 6000 years ago. Darwin's idea of natural selection was questioned in the beggining when the idea was just spread out. But slowly, people started to embrace the idea. > If there is anything wrong, or if anything is missing, please contribute and add on. Thank you. 1236081853 __ Unit Outline: __ 1.

 * 1) What are the key time-divisions, and evolutionary events in earth’s history?
 * 2) How does the fossil record give us clues to earth’s evolutionary history?
 * 3) Who was Charles Darwin and how did the social context in the 1800’s influence his work?
 * 1) How has natural selection affected our view of the natural world and our place in it?
 * 2) How has our understanding of natural selection “evolved” since Darwin’s time? Well we now know that the pace of evolution is not the same all the time. Sometimes it can be quick other times it can take a long time and sometimes there are periods of sameness.Decent with modification.
 * 3) What are the key components of natural selection theory? 1) Variation - differences among organisms inner workings is also known as physiology 2) selection pressure - slight differences provided by the environment eg. availability of water 3) struggle for survival eg. more organisms produced that can survive to reproduce. 4) differential survival & reproduction - some will survive and reproduce while others wont. 5) offspring resemble parents - something that you can choose to change
 * 4) What evolutionary patterns emerge as the result of natural selection?
 * 5) How can natural selection result in new species?
 * 6) When and where did the human species arise?
 * 7) Who are the key hominoid ancestors and what is know (and unknown) about them and the patterns of human evolution?
 * **Geologic Time and the Evolution of Life**

1. Darwin and the history of a revolutionary idea: his theories on descent with modification and natural selection (“Darwin’s Dangerous Idea”) 2. Evidence: Comparative anatomy: homologous, analogous, vestigial structures; Molecular evidence: DNA, RNA, Proteins 3. Patterns: Rates – (punctuated equilibrium); Convergence, Divergence and Coevolution (research assignment on species pairs)
 * **Natural Selection**

1. Natural Selection – Types of Selection: stabilizing, directional, disruptive, sexual (lab: natural selection) 2. Formation of Species – Isolating Mechanisms: geographic, reproductive, behavioral · **Human Evolution** 1. Fossils (becominghuman.org) 2. Modern Humans (skulls comparison lab)
 * **Speciation**
