This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Pacu fish have teeth that look exactly like people’s. They evolved to chew nuts that fell into the water (lemmy.world)

Is this an example of convergent evolution?

Hey it is! Kinda. I Think.

But why are human teeth shaped like this in the front? Not so much for nuts, right?

I thought the same thing so I looked into it! The pacu fish's front teeth aren't flat like ours. They're more like our molars, which serve the same purpose of being used for crushing (so it technically still is convergent evolution)
