By learning fossilized bones, experts understand the Actual physical physical appearance of earlier people And exactly how it adjusted. Bone sizing, shape, and markings remaining by muscles convey to us how those predecessors moved all over, held instruments, And just how the dimensions of their brains altered more than quite a long time.
