Does Humans Have Vibrissae?

Vibrissae are hairs specialized for tactile sensation, which grow around the nostrils or other parts of the face in many mammals, e.g. whiskers in cats and mice. A large part of the brain of some mammals is devoted to processing nerve impulses from vibrissae. Humans do not have them.

Why do humans not have vibrissae?

Short whiskers are microvibrissae, and they cannot be moved voluntarily. ... Humans used to have whiskers too (about 800 000 years ago we lost the DNA for whiskers), but have now largely integrated the function performed by whiskers into their brains, specifically into their somatosensory cortex.

When did humans lose their whiskers?

The animal cannot move the short ones voluntarily. We humans lost the DNA for whiskers around 800,000 years ago as other parts of our bodies became more sensitive, such as our fingers.
