The diagram shows a fossil of an ancient whale skull and a skull of a present-day whale. the ancient whale is extinct and is believed to be an ancestor of the present-day whale. what do these skulls most likely show that supports darwin’s theory of evolution? all populations can adapt and survive. only some organisms have a common ancestor. populations change slowly over time. populations rapidly become extinct.
i think it the letter A
The correct answer is option populations change slowly over time.
Evolution is a slow process in which a species changes over time.
The transition from teeth to baleen mouth involved a slow process which took millions of years, for example, the whales are thought to have evolved from Pakicetus inachus around 53 million years ago. These Pakicetus were land animals with large teeth and long skulls. Later they evolved into species with reduced pelvis which lived in marine habitats and were able to drink saline water .
Thus, populations change slowly over time is the correct answer.
they are known to reach a speed of 21 miles per hour
your answer is true
i am 100% sure
