"Grassland Theory Challenges Traditional Views on Human Evolution"
Originally Published 2 years ago — by The Times
The theory that ancient apes first adopted an upright posture while living high in the canopies of dense forests may have to be rewritten after a new study challenges the idea. The research suggests that the east African home of these apes was not a dense forest, but rather a grassland. This reappraisal of when Africa gained its earliest grasslands could change the story of how our distant ancestors first came to stand upright.
