What were the different stages of evolution of man?

Answer 1

Evolution does not exactly work in specific stages. It is not like a clutch system, in which evolution starts at first gear, and as it accelerates, moves to higher gears. It is simply progressive, but ongoing. You cannot say something is in 'stage 1' of its evolution, only that it is early-on. True, the title 'human' has been bestowed to less-evolved species than Homo sapiens, though this is technically incorrect. Species from which modern humans evolved have been from various earlier-existing genera, but such classification is, to some degree, a grey-area science; it's hard to classify exactly at what point something ceases to belong to one species and starts to belong to another, let alone in the case of a change of genus.

The closest thing I can give to answer your question is that humans evolved from smaller, less sophisticated Great Apes, which evolved from Lesser Apes. Lesser Apes evolved from monkeys, which evolved from less complicated primates. Primates, if you look far enough back, evolved from versatile, rodent-like animals. These small rodent-like animals evolved from even smaller, less complicated animals. If one follows this progression far enough back, one finds a series of prokaryotic cells, that emerged from puddles of amino acids, to one day become humans.
