Question

Fossil evidence of several species has been found linking modern-day whales to their ancient land mammal ancestors. This series of fossils provides evidence for

adaptive radiation because the whales retained most of the skeletal shape and structure of their ancestors
gradualism because one species evolved slowly and steadily over time by small genetic and physical changes
co-evolution because the different mammals evolved together to interact with the changing environment
punctuated equilibrium because one species evolved into several related species over a long period of time

Answer 1

The answer is B-Gradualism because one species evolved slowly and steadily over time by small genetic and physical changes. I hope this helps.

Answer 2

Answer:

gradualism because one species evolved slowly and steadily over time by small genetic and physical changes.

Explanation:

• The fossil evidence that have been collected relates to the present species of the land and ocean mammals as the whales as their ancestors and other had the same process of evolution.

• This is gradualism is that process that slowly changes adjusts and evolves gradually with the process of time and has natural variation.

• And newer species evolves slowly over the older ones and rather than any abrupt and major changes taking place over the long periods of time.
