What is the type of rock that fossils are found in?

Sedimentary

A rabbit population exhibits variation in fur thickness in a temperate habitat. A gradual and lasting cooling in the habitat’s climate decreases the diversity of the rabbits’ fur coat thickness. What is the reason for this decrease? Will the thinner coated survive or will the thicker coated survive?

The rabbits with the thicker coat will survive.

True or false: The traits that survive and continue in the future generations are introduced by immigrating species. If true, just write true. If false, rewrite the statement to make it true.

False: The traits that survive and continue in the future generations are already present in the population.

Why do taxonomists sometimes change the system of classification?

New information regarding the structure, metabolism, and DNA of organisms are found.
