PLEASE HELPPP!! I NEED THIS ASAP! WILL GIVE BRAINLIEST IF IT IS CORRECT! 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.

(I can't insert the picture, but its an animated picture of a Pakicetus and a Gray 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.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
