Did Ancient Humans Use Echolocation?

4. Thought provoking!

Humans in dark caves could be subject to predation. I would think fire not only lights the way but serves to defend.

Our first learning organ is the ear. We eavesdrop on mommy's heart beat before birth. We live in such a visually bombarded eye candy world that our poor ears are not doing what they should do. If you are in the Amazon where some crazy people purchase kitty cat predators as adorable until they strike back. Occasionally they just dump them in the forest. If you are a human in those regions baths are not your friend as you certainly do not want to have a less disagreeable odor attracting a predator. And your ear will take over as primary sense organ as your eyes will be blinded by the vegetation. The ear will listen carefully to the environment and may give you an indication that something is lurking nearby, in my case a Yanomami female.
