Final answer:
The time period of Homo is from 2.5 million years ago to the present.
Step-by-step explanation:
The time period of Homo is option 1) 2.5 mya - present.
The first hominid fossils appear in the late Miocene, 10 to 5 MYA. Sometime between 7 MYA and 4 MYA, hominids moved out of the trees and began to adapt more fully to a ground-based living niche. Homo habilis, the first known species in the genus Homo, lived from about 2.5 to 1.4 million years ago.
