The wise-man, whose brain was sufficiently evolved about fifty thousand years ago, is known by the scientific name:

1. Brain evolution of upright man continued for about a lakh years and discovered fire. 2. By around fifty thousand years ago the brain had evolved enough to be called wise-man. 3. Wise-man is given the scientific name Homo sapiens. 4. So the correct name is Homo sapiens. 5. Trap (Homo erectus): this refers to the earlier upright-walking man, before wise-man. 6. Trap (Ramapithecus): this is the much earlier first human-like ape, not wise-man. 7. Trap (Homo habilis): this skilled human stage came before wise-man. 8. Hence the fifty-thousand-year-old wise-man is Homo sapiens. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 1 "Heredity and Evolution", p.19_
