Step-by-step explanation:
Homo habilis is a species of extinct human evolution, belonging to the class of hominids, considered the first human being itself. This species, like all early humans, had a very different lifestyle than ours. Homo habilis was a nomad species, meaning they did not settle in an area to grow their food.
