Think about a cladogram that shows the evolutionary relationship between humans, chimpanzees, and gorillas. A cladogram of these species would currently show humans and chimpanzees with a more recent common ancestor compared to gorillas. Which piece of evidence, if true, would most likely weaken this hypothesis?(1 point)

Responses

a. Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees.

b. DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla's DNA sequence.

c. The cells of the eye in embryos of gorillas and humans follow a similar pattern of development while the eye cells of chimpanzee embryos are different.

d. Amino acid analysis of a certain protein show significant differences in the sequence of amino acids between humans and gorillas.

The correct answer is a. Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees. This piece of evidence would suggest that humans evolved earlier than chimpanzees, which contradicts the hypothesis that humans and chimpanzees have a more recent common ancestor compared to gorillas.
