"Abilities Evolution Took from Us": animals sense things we miss


Sci-Show explains “Abilities Evolution Took from Us”.
  

Call it “losing it”.   That has some meaning in my own life.

The speaker talks about the residual human pineal gland, which does process melatonin, but which no longer functions as a “third eye” as in some amphibians.

Some fish (eels) can sense or generate electricity.  Land animals lost that ability because it doesn’t work in the air.  But when the went back to the ocean, whales and dolphins gained something similar, which evolved into a sonar. 
  
He also discusses pheromones, which are detected in a nasal gland which is almost inactive in humans, where visual stimuli became more important.
