During which period did humans first appear on Earth? Quaternary Neogene Paleogene Cenozoic
anyanavicka [17]

The answer is Neogene

Explanation:

It cannot be Cenozoic because that is an era. Not a period. Paleogene, Neogene, and Quaternary (our current period) are all periods within the Cenozoic Era (our current era). On the geologic time scale, there are Eras, Periods, and Epochs (and a few more classifications). Humans first appeared in the Miocene epoch which is an epoch in the Neogene period (in the Cenozoic era).

This is why the answer is Neogene.

Hope this helps...
