Question

Do you find the interpretation of chromosome 2 convincing evidence that humans share a common ancestry with other great apes? Explain.

a) Yes, the similarities in chromosome 2 support the theory of common ancestry.
b) No, there is not enough evidence to conclude a common ancestry from chromosome 2 alone.

Answer 1

Yes, the similarities in chromosome 2 support the theory of common ancestry.

Step-by-step explanation:

Yes, the similarities in chromosome 2 support the theory of common ancestry.

Chromosome 2 in humans is unique because it is the result of the fusion of two separate chromosomes that occurred after humans diverged from their common ancestor with chimpanzees. This fusion event is supported by the presence of telomeres (DNA sequences at the ends of chromosomes) and a highly repetitive DNA sequence called the centromere in the middle of chromosome 2.

This fusion event is not seen in other great apes, but the similarities in chromosome 2 between humans and other great apes provide strong evidence that humans share a common ancestry with them.
