Hominids diverged from apes in the last
Anatomically modern humans in the last
Explanation:
- The age of the Earth is about
4.54 billion years.
So if we represent the history of the Earth by one year, then
4.54×109365.25≈12.5 million years.
- Hominids separated from apes about
7.5 million years ago.
So the time of the evolutionary divergence of hominids would be represented by:
7.512.5=0.6 days≈14.5 hours
- Anatomically modern humans date from about
200000 years ago.
That would be represented by:
2×10512.5×106=0.016 days≈23 minutes.
So anatomically modern humans have been around for the last
