The First Fish to Evolve The Ability to Walk Never Even Left The Ocean

Have feet, won't travel.

Some of the very first sea creatures to be able to walk didn't make the most of their new evolutionary advantage and stayed in the oceans, according to new research, which suggests the ability to walk originated much earlier than previously thought.

The research is based on a genetic analysis of the brain cells of the little skate fish (Leucoraja erinacea), one of the most primitive animals with a backbone.

It turns out the brain systems controlling its movement are very similar to those found in mammals. That suggests these sea creatures were the first to learn some kind of walking-like behaviour.

The team of scientists also recorded footage of little skate embryos making walking-like movements along the bottom of a fish tank, movements that have been seen in previous observations:

1. Humph. No gratitude in that fish, apparently.

Tsk. That’s like getting your cat a gorgeous bed, but she doesn’t care about that. She just wants the box.

2. ha! I was trying to think of a political equivalent

Like: Trump voters have plenty of evidence that he's not working for them. Indeed, GOP voters have the same information. But they're not using it.

3. I've always thought Adam & Eve

were walking fish "tossed" out of the true garden of Eden, the Mother Ocean. I kind of equated it with being left on beach when tide went out.

the apple/tree/snake part was a little difficult to tie in.

4. The walking thing

Had to have the breathing thing attached.
