Answer:
Anatomy is the main feature that distinguishes Homo Sapiens from its predecessors.
Step-by-step explanation:
Human beings developed from now-extinct primates, this process known as human evolution shows how these primates evolved throughout the years to reach the human form that we now have in the present time. The humans you find living on Earth today are considered Homo sapiens, a species that first evolved in Africa around 350.000 years ago. The main difference between the Homo Sapiens and its predecessors like the Homo Erectus or Homo Habilis, is the Homo sapiens' anatomy. The brain size of the Homo sapiens was bigger than its predecessors, and in fact, present-time humans have the biggest size of all of the human species of all time. Homo sapiens' anatomy is the main feature that distinguishes them from the rest, with less prominent jaw lines and softer brow bridges.
