1

darwin’s inferences

1. individuals with traits better suited to the environment will survive and reproduce in higher numbers
2. favorable traits will accumulate in the population over generations due to unequal survival and reproduction

2

population

individuals of the same species that are living in the same area at the same time

3

natural selection

individuals with adaptations will survive better and leave more offspring

4

adaptations

a heritable trait that increases an individual’s biological fitness in a particular environment relative to those that lock that trait

5

biological fitness

the ability of an individual to survive and produce offspring

6

artificial selection

species modification over generations by selective breeding for desired traits

7

homology

a similarity that exists in species descended from a common ancestor

8

genetic homology

similarity in the DNA sequences of different species

9

developmental homology

seen in embryos of different species

10

important points about natural selection

1. individuals do not evolve, populations do
2. acclimation is not adaptation (phenotypic change does not equal genotypic changes)
3. evolution is not goal directed
4. evolution is not progressive
