Question

What characteristics do all humans have in common?

Answer 1

Characteristics that all humans have in common:

1. Bipedal – humans walk on two legs instead of on all four.
2. Binocular vision – provides a complete 190-degree field of view for humans, as the eyes are in the front of the face (rather than the sides of the head).
3. Color blindness – We all can see a different spectrum of colors. Most animals can't see any color at all.
4. The larynx (voice box) – Deep in the human throat and has increased flexibility in the mouth, tongue, and lips, allowing humans to speak, pitch, and sing.
5. Brain – The adult brain has about 86 billion neurons, of which the cerebral cortex has 16 billion neurons, while other animals have fewer neurons.
