time to bring it back then, alongside horn implants, and third tit.

How about a third eye?

"The parietal eye is found in the tuatara, most lizards, frogs, salamanders, certain bony fish, sharks, and lampreys...It is absent in mammals, but was present in their closest extinct relatives, the therapsids"

wings

It's not all it's cracked up to be - https://craphound.com/someone/Cory_Doctorow_-_Someone_Comes_...

Wings are so fascinating. Flying animals have their whole body, from their brain, digestive system, down to their bones internal structure and function [0] optimized for flight. That's where we see species giving up flight ability to get a stronger body, and I wonder what it would take for us to do the reverse to be able to use these wings in any way.

Just need to go to Titan

atmosphere thick enough, gravity low enough

We'd definitely have to give up long gestation and with that, live birth, and probably a good amount of cranial capacity due to weight and energy budget tradeoffs.

Huh? Bats have most of those those, more than most other mammals their size.

Bats do not have the cranial size of humans; that's kind of the point. They may have a loosely comparable cranium to body mass proportion, but allometric mass scaling matters with respect to physiological adaptation, quite a lot[0].

It would be an awful trade. Weaker, dumber, slower. All for something that isn’t very good and we wouldn’t use very much.

People would prefer to drive rather than fly because you’ll get soaking wet. Unless you just go around naked or something.

Would make sitting down rather uncomfortable.

I'll buy new chairs.

Would be handy for navigating the warp. ;)

Third nipples are quite common believe it or not. Most people with them believe they’re moles.

Yup, I've seen a few. There's even a line on each side of the body that they tend to emerge along, arcing from the armpit down to the crotch.

I'd I'd be drinking milk, it would be out of my nostrils right about now.
