Question

State which type of evidence of evolution the following is an example of: Comparing human hemoglobin with hemoglobin of chimpanzees, rabbits, chickens, and sharks, reveals that humans have the fewest amino acid differences with chimpanzees.

a) Fossil record
b) Comparative anatomy
c) Protein and DNA sequences
d) Biogeography

Answer 1

Comparing human hemoglobin with hemoglobin of chimpanzees, rabbits, chickens, and sharks, reveals that humans have the fewest amino acid differences with chimpanzees, which is an example of protein and DNA sequences as evidence of evolution. Option c.

Step-by-step explanation:

This is an example of c) Protein and DNA sequences as evidence of evolution. By comparing the hemoglobin of different organisms, such as humans, chimpanzees, rabbits, chickens, and sharks, scientists can analyze the amino acid differences. The fact that humans have the fewest amino acid differences with chimpanzees suggests a closer evolutionary relationship between the two species.
