malfutka [58]

We can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.

<h3>What is bipedalism?</h3>

Bipedalism was the adaptation of early human ancestors to abandon movement on all fours and begin to walk up-right. This was a vastly important adaptation as it provided the early humans with freed hands, allowing for many other uses such as tools and social cues.

Therefore, we can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.
