Fun fact: Humans are supersensitive to the smell of rain (the substance geosmin) - the nose needs only 5 molecules per trillion.
For comparison, we detect this smell 200,000 times better than a great white shark senses blood in water.
Why does a human need such a powerful rain detector? What were our cave-dwelling ancestors so afraid of?
What kind of creature came with the rain? Is it still here?!
