“Fish, amphibian, and reptile, warm-blooded bird and mammal – each of us carries in our veins a salty stream in which the elements sodium, potassium and calcium are combined in almost the same proportions as in seawater.
“This is our inheritance from the day, untold millions of years ago, when a remote ancestor, having progressed from the one- to the many- celled stage, first developed circulatory system in which the fluid was merely the water of the sea.”
from ‘The Sea Around Us’, Rachel Carson, 1951. Found in ‘The Sea’, Lapham’s Quarterly Vol VI, No. 3, Summer 2013.
