A theory popped into my head the other day. Hear me out... I was discussing with my son the water cycle and the salinity of the oceans. Not to get into the source of all water on earth (space), evaporation as the creation of fresh water and mineral erosion making our seas salty, this is not about all of that.
What if... the salinity of our blood, as terrestrial creatures, is the same level of salinity in the oceans at the time that our ancestral creatures crawled away from the sea?
I exploded my brain with this one, my kid's brain too! Enjoy barracuda and the mental gymnastics!
