Question

Indicate how biochemistry provides evidence of evolution.

Solution

Verified

Step 1

1 of 2

Recall that evolution refers to the change in allelic frequency in a population over a period of time, and scientists make use of biochemical data of organisms to infer the degree of relatedness of organisms.

Scientific data have illustrates that common ancestry can be determined in the complex metabolic molecules that various organisms share. For example, the genetic information of the organisms is sequenced to note their similarities and differences.

Additionally, some scientists look into Cytochrome c, a highly conserved enzyme that is important for respiration. Here, the evolutionary pattern can be traced, where the more closely related species have a greater number of shared sequences.
