Dinosaurs and birds "magnetic compass"

It must date back to when we were fish. Animals that don't travel much and get lost would have this area of the brain shrink back and used for other important tasks. At one point the magnetic field of the earth was much stronger, so it would be easier to evolve this ability.

There used to be two competing theories about magnetic sense
some thought it came from iron-binding molecules
others thought it came from a protein called cryptochrome

latest study really shows, that iron binding cells + cryptochrome protein are working in tandem for the animal to use this

bats, rats, butterflies, it was way before dinosaurs and birds

If you look at a picture of a t-rex with the understanding that it is an intentional gene-splice of a bird and a crocodile, you will very clearly see both the bird and the crocodile in the image.

There was no evolution.

This is fascinating.

Some years ago scientists at CALTECH (California Institute of Technology in Pasadena) discovered that humans possess a tiny, shiny crystal of magnetite in the ethmoid bone, located between your eyes, just behind the nose.

Magnetite is a magnetic mineral also possessed by homing pigeons, migratory salmon, dolphins, honeybees, and bats. Indeed, some bacteria even contain strands of magnetite that function, according to Dr Charles Walcott of the Cornell Laboratory of Ornithology in Ithaca, New York, "as tiny compass needles, allowing them [the bacteria] to orient themselves in the earth's magnetic field and swim down to their happy home in the mud".

Since the discovery that magnetic orientation by bacteria was due to the presence within the organism of magnetic particles of the ferric/ferrous oxide, magnetite, the search has begun for other biogenic deposits of inorganic magnetic material and ways in which the possession of such material might confer on the organism the ability to orient to ambient magnetic fields.
