Comment on How do you think early humans survived without water bottles? Did they just live next to water sources all the time?

You know the smell dirt makes when its wet? It’s called petrichor and humans can smell it better than sharks smell blood in the water. It is detectable by the human nose at 0.4 parts per BILLION. This gave early humans a huge advantage in finding water when needed. en.m.wikipedia.org/wiki/Petrichor
