Hint: Human evolution

Human ancestors:

1. Modern humans, or the species Homo sapiens, appeared comparatively recently, between 315,000 and 150,000 years ago.
2. The human lineage, on the other hand, has survived a long and difficult voyage.
3. Our genetic route took many ups and downs over millions of years.

Genus/species	Age of appearance (in million years)	Skull	Posture	Diet
Homo habilis	1.6-1.8	Lightly build jaws	Fully erect.	Omnivorous
Homo erectus	1.7-1.5	Thick, low forehead, heavy jaws and brow ridge	Fully erect,155 cm tall.	Omnivorous and cannibal
