This animal lived between 3.85 and 2.95 million years ago in Eastern Africa. This animal had a powerful chest and strong upper arm muscles necessary for tree climbing and an upright body and stride for walking.
As early as 32,000 years ago, our species demonstrated which capabilities?
How do we know Sahelanthropus walked upright?
The position of the foramen magnum on the underside of the cranium which indicates that the head was held upright.
This species, one of the earliest members of the genus Homo, has a slightly larger braincase and smaller face and teeth than in Australopithecus. This species was thought to represent the first stone-tool maker.

Steno’s Three Laws
Principle of Superposition: oldest strata are at the bottom in an undisturbed sequence of strata
Principle of Original Horizontality: all strata are horizontal when they form.
Principle of Original Lateral Continuity:
Strata originally were unbroken flat expanses; Interrupted by erosion
- 3.7-billion-year-old sedimentary rocks contain chemical evidence suggesting life
- The graphite particles contain ratios of carbon isotopes that suggest they are derived from living cells
A spectral pattern used to determine the motion of objects.
If the lines are moved to the red side of the visible spectrum, the wavelengths of light are being pulled apart, and the object is moving away from us.
