Evolution:
1. Definition
2. Role of time
3. Role of change in survival
1. Heritable changes over time; DNA changes or modifications that occur in a POPULATION over a period of time
2. Time is relative; evolution can span thousands of years (humans) to hours (bacteria)
3. Animals survive as a RESULT of change. That is, animals DO NOT CHANGE to survive.
Describe Aristotle's contributions to evolutionary history
developed scale of nature: based on complexity of organism, and that species do not change

Humans > Animals > Plants
Describe Linneaus' contributions to evolutionary history
developed "binomial system"
developed (genus, species) classification
Describe Hutton's contributions to evolutionary history
developed "gradualism"
changes occurred through time gradually with intermediates visible
Describe Lamarck's contributions to evolutionary history
developed "use vs disuse" hypothesis
body parts grew proportional to use; acquired traits were inherited
first indication of theory of evolution; not explicitly stated
Describe Malthus' contributions to evolutionary history
developed "geometric vs arithmetic growth"
population undergoing geometric growth while food supply was growing at arithmetic (linear) trend; stated we would eventually run out of food
Describe Cuvier's contributions to evolutionary history
developed "punctuated equilibrium"
through fossil examination he determined that extinctions occurred, sometimes by catastrophes which produce differences; rapid change, no intermediates
Describe Lyell's contributions to evolutionary history
developed "principle of uniformity"
stated that rate of change is always constant
Describe Darwin's contributions to evolutionary history
Evolution occurred through "natural selection"
Describe Wallace's contributions to evolutionary history
developed theory of natural selection at the same time as Darwin, but did not publish in time
Describe some proponents of Darwin' theory of evolution.
1. there must be a large population size
2. Variation is present
3. The population growth always seems to be limited
4. Genetic fitness "survival of the fittest"
What is the synthetic theory of evolution
combination of Darwin and Mendel. The role genetics plays in evolution
