Based on molecular evolution, which one of the following is close to humans ?

  • A.Orangutans
  • B.Gibbons
  • C.African apes
  • D.Lemur

Answer: C

The closest to humans are the African apes.

DNA and protein comparisons show that humans are most closely related to the African apes, chimpanzees and bonobos above all, with whom we share about 98-99% of our DNA sequence, followed by gorillas. The human and chimpanzee lineages separated roughly 6-7 million years ago.

Orangutans, the Asian great apes, branched off earlier (about 13-16 million years ago), gibbons (the lesser apes) earlier still, and lemurs are prosimians, among the most distant primates from humans.
