Answer:

The correct answer is option A. "Some animals exhibit similar proteins".

Explanation:

There is plenty of evidence that support the theory that life changes over time, and that living species have different common ancestors. Regarding the evidence provided by analysis of biological chemicals, the fact that some animals exhibit similar proteins supports this theory. This type of proteins are called homologous proteins, and is possible to construct phylogenetic trees based on sequence and structure similarities among them.
