a.The skeletons of mammals that existed 150 million years ago are different from the skeletons of mammals that exist today. FOSSIL RECORD

b. The front limbs of humans, bats, birds, and whales all have a similar bone structure. Comparative anatomy

c. All vertebrates contain the protein hemoglobin, but the structure of the hemoglobin molecule varies from one species to the next. Molecular evidence

Explanation:

Fossil records can be described as life history that is predicted by the use of fossils. Hence, the statement a 'The skeletons of mammals that existed 150 million years ago are different from the skeletons of mammals that exist today'  depicts the evidence to be fossil record.

The similarities or differences present between the anatomy of different kinds of species is termed as comparative anatomy. Comparative anatomy is very useful in studying evolution as it tells us about common ancestors of different species. Hence, the statement b 'The front limbs of humans, bats, birds, and whales all have a similar bone structure' is an example of comparative anatomy.

Molecular evidence can be described as any evidence which tells us about similarities or differences in organisms at molecular or cellular level. Hence, the statement c 'All vertebrates contain the protein hemoglobin, but the structure of the hemoglobin molecule varies from one species to the next' is description of comparative anatomy.
