Early humans evolved in ecosystems unlike any found today

To understand the environmental pressures that shaped human evolution, scientists must reconstruct the ecosystems in which they lived. Because putting together the puzzle of millions-of-years-old ecosystems is a difficult task, many studies draw analogies with present-day African ecosystems, such as … Continue reading
