Question

What are the chromosomal similarities found in apes and man? What do such similarities indicate?

Answer 1

Chromosomal Similarities between Apes and Man:

1. Both humans and great apes (chimpanzees, gorillas, orangutans) have similar chromosome structures and gene arrangements.

2. Humans have 46 chromosomes (23 pairs), while apes like chimpanzees and gorillas have 48 (24 pairs), showing a close genetic relationship.

3. The human chromosome number 2 was formed by the fusion of two ancestral ape chromosomes, proving a shared ancestry.

4. The DNA similarity between humans and chimpanzees is about 98–99%.

What these similarities indicate:

These chromosomal similarities indicate that humans and apes evolved from a common ancestor, and their evolutionary lines diverged millions of years ago.
