But it's a movie about the first boney fish to evolve jaws and how they disrupted the entire ocean with this innovation.

@futurebird Indeed! Before lungs or legs or hard-shelled eggs, there were #JAWS!
In the Silurian, the hinged #jaw ruled the waves!

Agnieszka R. Turczyńska@futurebird A friend of mine, who is a palebiologist, once shared with me that using phosphorus to build teeths is an evolutional development. Earlier organisms used only calcium for that. And even if phosphorus is much less abundant in the nature, the hardness of teeth given by the phosphorus granted so much advantage over calcium-only-teeth organisms, that it has evolutionary won.

PS. Sorry, accidentally I've sent the previous version of the toot prematurely, then got sucked into something urgent.
