this may be off-topic but an interesting read. happy fishing! What People Owe Fish: A Lot
By NATALIE ANGIER
Being a resolute hydrophobe who has no more desire to go for a swim than might a kitten in a bag or Luca Brasi in “The Godfather,” I admit I never thought of myself as a large, scaleless fish out of water.
Yet after reading Neil Shubin’s brisk new book, “Your Inner Fish,” and speaking with other researchers who use fish to delve into the history of vertebrates in general and ourselves in particular, I realize that many traits we take pride in, the body parts and behaviors we exalt as hallmarks of our humanity, were really invented by fish.
You like having a big, centralized brain encased in a protective bony skull, with all the sensory organs conveniently attached? Fish invented the head.
You like having pairs of those sense organs, two eyes for binocular vision, two ears to localize sounds and twinned nostrils so you can follow your nose to freshly baked bread or the nape of a lover’s irresistibly immunocompatible neck? Fish were the first to wear their senses in sets.
They premiered the pairing of appendages, too, through fins on either side of the body that would someday flesh out into biceps, triceps, rotating wrists and opposable thumbs.
Or how about that animated mouth of yours, with its hinged and muscular jaws; its enameled, innervated teeth; and a tongue that dares to taste a peach or, if it must, get up and give a speech? Fish founded the whole modern buss we now ride.
The fish’s tale of firsts is a tall one. “The backbone that holds us upright, that’s a fish invention,” Dr. Shubin, a paleontologist at the University of Chicago and the Field Museum, said in an interview. “The cranial nerves that we use to control the muscles in our jaw, that we use to talk and to hear, they relate to a fish’s gill arches. The basic wiring in our skull, the body plan we take for granted, that’s part of our story. It’s all from fish.”
Our inner fish extends beyond physicality. New research reveals that many fish display a wide range of surprisingly sophisticated social behaviors, pursuing interpersonal, interfishal relationships that seem almost embarrassingly familiar.
