why do wisdom teeth grow?
In: Biology
The same reason all other teeth grow – our genetics contain instructions for those teeth to grow.
Now, they are problematic because, over time, we have evolved smaller jaws than our ancestors but did not also evolve fewer teeth. The jaws of our ancestors had more than enough space for wisdom teeth, but our modern jaws are just too small.
Like many aspects of evolution, it is one of those things that just didn’t change because it just didn’t matter much to overall survival.
