How did he figure this out? Tested the time balls of iron took to cool after being heated and used the results to estimate the Earth's age at 75000 years.17) Who was Georges Cuvier? What was catastrophism? First scientist to examine the idea of extinction.the idea that the Earth has withstood multiple catastrophic events which caused extinction and shaped the Earth.18) Who were James Hutton and Charles Lyell? Hutton had the idea of Uniformatarianism and Lyell popularized it19) What was Uniformitarianism? Uniformatarianism: Processes that are at work today were also at work in the past. So wind, erosion, earthquakes, etc. gradually changed, and are changing, the face of Earth.20) Who was Jean-Baptiste Lamarck? What was his contribution to evolutionary theory? Major evolutionary thinker before Darwin. Developed theory on the Inheritance of Acquired Characteristics; changes to an individual over their lifetime would be passed on automatically to their children.21) Who was Thomas Malthus? How did his ideas effect Darwin’s thoughts? Interested in the relationship of human populations to resources. Wrote 'An Essay on the Principle of Population' in 1798. This essay influenced Darwin.Lecture 4 (February 3)Darwin and His Research22) What was Darwin’s life like prior to his discovery of natural selection? Where did he go? How did histravels affect his thought process? He was the son of a well to do family originally studying to be a doctor. Didn't become a doctor but found out about evolutionary theory of the time and joined the HMS Beagle on a world trip where his ideas on evolution and natural selection took shape.23) Who was Alfred Russel Wallace? Another scientist who came up with the same ideas on natural selection as Darwin24) What are the four main tenants of Darwin’s theory of natural selection? 1. In each generation there are more offspring produced than can survive2. Offspring vary; though not all the same, they do resemble their parents and siblings3. Some of these variations are better suited for survival than others4. The competition for resources favors individuals with these variations, resulting in that individual's survival25) What does the term “fitness” mean? 'Fit' in Darwinian terms refers to an individual's ability to live to reproductive age, find a mate, and reproduce successfully.26) What is an adaptation? the functional response of populations to the environment that result from natural selection. 27) What qualities or characteristics must a feature have to be considered an adaptation? it must be heritable, functional, adaptive, and useful to its current function.28) What is an out-dated adaptation? are features that formed for a purpose but are no longer needed for that purposeLecture 5 (February 7)Natural Selection and Evolution29) How does constraint through character correlation work? selecting for one trait or character that happens to be related to another trait as well. For example, when selecting for beak depth in birds, beak width is automatically selected for as well30) What is a physical constraint? something that can't evolve due to basic physical properties.31) What is a genetic constraint? not enough genetic variance in a population to evolve or make changes32) How is artificial selection evidence for natural selection? Humans have domesticated plants and animals and chose traits in them that benefit human life.
