The most accepted theory in human evolution is:

The correct answer is Option (2) → Ramapithecus → Homo habilis → Homo erectus → Homo sapiens

Ramapithecus (about 15 mya) came first; then Homo habilis (about 2 mya), Homo erectus (about 1.5 mya), and finally Homo sapiens.

Option (1) Homo habilis → Homo erectus → Ramapithecus → Homo sapiens — Incorrect. Ramapithecus, a hominid-like primate of about 15 mya, comes first in the sequence, not third. Homo habilis (about 2 mya) came long after it.

Option (2) Ramapithecus → Homo habilis → Homo erectus → Homo sapiens — Correct. Ramapithecus → Homo habilis → Homo erectus → Homo sapiens.

Option (3) Homo erectus → Homo sapiens → Homo habilis → Ramapithecus — Incorrect. This reverses the order. Homo sapiens is the latest form, so it cannot come before Homo habilis and Ramapithecus.

Option (4) Homo habilis → Ramapithecus → Homo erectus → Homo sapiens — Incorrect. Ramapithecus (about 15 mya) lived before Homo habilis (about 2 mya), so it cannot come second. The order is Ramapithecus, Homo habilis, Homo erectus, Homo sapiens.
