Concept 1

100

a feature that allows an organism to better survive in its environment.

adaptation

100

T/F

Evolution will occur if at least one of these conditions is met:

Population is small.

Non-random mating.

Migration.

Mutations.

Natural selection.

True - only 1 condition needs to happen for the population to evolve!

100

Developed his theory of natural selection to serve as the mechanism for how evolution occurs.

Charles Darwin

Survival of the Fittest is scientifically known as

Natural Selection

100

Also known as non-random mating.

Sexual Selection

Concept 2

100

when two populations of organisms form a specialized relationship and thus change in response to each other

Coevolution

100

When unrelated species evolve similar characteristics because they live in similar environments

Convergent evolution

100

Slow, constant changes over a long period of time

Gradualism

100

Bursts of change followed by periods of stability

Punctuated equilibrium

100

A number of different species arise from one common ancestor

Divergent evolution
