Evolution

Question 1

Convergent evolution

Answer 1

When distant species develop similar adaptations and niches.

Question 2

Coevolution

Answer 2

Species evolve to become more dependent upon one another. Over millions of years species that intersect closely often adapt to one another.

Question 3

Adaptive Radiation

Answer 3

Evolution of many diversely adapted species from one common ancestor. Over a relatively short period of time.

Question 4

Stabilizing Selection

Answer 4

Selective pressures that select against the 2 extremes of a trait. Population experiences stabilizing selection.

Question 5

Divergent evolution

Answer 5

Isolated populations evolve when geographical barriers separate members. As generations pass they can no longer interbreed
