Which of the following describes how biological chemicals provide evidence to support that life changes over time?

A. Some animals exhibit similar proteins

B. Some animals exhibit similar structures, possibly due to a common ancestor

C. Some animals exhibit structures that are no longer used for any purpose

D. Some animals exhibit similar stages of embryonic development

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.

The fact that some animals exhibit similar proteins serves as one of the evidence of evolution.

What is evolution?

It is the descent with modification of living organisms from a common ancestor.

There are several evidence being used to support the theory that all living organisms came from a common ancestor. These evidence include anatomical, biochemical, and physiological evidence.

The fact that some living organisms have proteins that are similar both in structure and function is one of the biochemical evidence being used to support common ancestry.
