Question

What kind of shelter did Homo habilis build or use?

Answer 1

"At site DK in Olduvai Gorge Bed I, Oldowan artifacts and fragmentary animal bones were associated with natural lava blocks, 10-25 cm across, clustered in a circle 4-5 m in diameter [...] A partial skull of Homo habilis was found at the same level nearby. Conceivably the circle marks the position of a stone windbreak or the base of a brush superstructure, but it also could have been created naturally when the radiating roots of a tree fractured a lava layer that lies directly underneath [...]"

Answer 2

Homo hablis (2.4 million years old), was probably hairy enough, that he didn't need clothes or a shelter to protect him from the climatic variances!
