Only eventually they decide they’ve had enough of the world inside your mouth and they start hurting until you get them removed. But why do they appear in the first place? Because of evolution, of course. Attempting to better understand the evolution of our teeth, a team of researchers reveal that prehistoric teeth evolved according to inhibitory cascade.
More and bigger teeth
3d cube desktop keygen After attempting to find the reason behind our teeth’s evolution for over a decade, scientists have finally figured out that the answer is much simpler than they had anticipated. It has to do with an evolutionary trend instead of something particular to humans, but I’ll get into that a bit later.

However, previous hominid species had much bigger molars. They were so big, in fact, that they used to chew on surfaces up to two or four times those we are used to.

The inhibitory cascade
hoe gebruik ik een crack Since teeth can tell us a lot about the lives of our ancestors, researchers used fossilized teeth of both humans and animals and came to the humbling discovery that we did nothing special – or more like nothing at all – in order for our teeth to change so much.
arcon moj dom crack As humans, we are animals. Mammals to be more specific. And this is exactly what triggered the change. We’re not the only ones to suffer such a huge transition at the level of our chewing surfaces. In fact, almost all mammals went through the same change. And it’s owed to something called the inhibitory cascade.

That molar, in its turn, determines the size of the one next to it, and so on, eventually determining the size of all of our teeth.
