b. Directional selection

A population of birds live on an island where seeds are their primary food source.

Disruptive selection b. Directional selection c. Stabilizing selection d. Artificial selection

d. The fossil record provides evidence that organisms have changed over time.

How do fossils support evolution? a. Individual species disappear and reappear in the fossil record over time. b. The fossil record provides evidence that all organisms developed at the same time. c. Organisms in the fossil record are identical to living organisms. d. The fossil record provides evidence that organisms have changed over time.
