Would be cool if we had tails, so I could wag it with my future dog!

But imagine if your tail was hairless :/

I imagine that it could still look cool if it were shaped/tapered in just the right way, maybe somewhere between that of a Sphynx cat and a lizard.

Meanwhile, 140k years ago, our 3rd civilization approached our current level of tech. Fashion designers, specifically a group lead by Argot the Great, decided the tail made pants difficult, and broke the lay of suit jackets. So they hired radicals to genetically engineer a retrovirus, to remove the tail. This worked, but due to unconsidered balance issues, all tail devoid children lost the capability for bipedal bala…

Dehydrate!

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" https://en.wikipedia.org/wiki/Parietal_eye You may wish to consult your pineal gland.

wings

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.

The greatest thing on this thread is how disappointed we all are for some bizarre reason lol. It would be cool to get them back for better balance.

A prehensile tail would do so much for my cooking skills... the possibilities are infinite. Wait - I finally found a use case for Neuralink that I can cheer for!

You don't necessarily even need invasive surgery to control an additional limb: https://spectrum.ieee.org/human-augmentation

I can guarantee that each of those sentences is repeated verbatim somewhere on a certain website.

EDIT: I swear I meant to type "almost verbatim." That said, Google is no longer a good authority for, "Is it somewhere online?".

Would make sitting down rather uncomfortable.

You can just Google them in quote marks, and they only appear here.

A tail is grabbable. I'd think in primate fighting, a tail would be big negative. It could be grabbed. Can you imagine Chimp fights if they had tails that could be held on to and the owner dragged around.

Hair is much worse in that regard, as the tail would be positioned too low to practically grab (it would asking for a knee to the face or punches to the back of the head or spine if you tried). I think the driver is more likely to be bipedality. A tail doesn't provide a lot of benefit for balance or rearside whisker utility when moving on two legs, and would interfere with sitting and lying postures. I think humans a…

>and would interfere with sitting and lying postures.

I think that assumes that a hypothetical modern human tail would still be attached to the spine. A tail structure attached to the main body only through soft tissues could be flexible enough at the root to not be an issue.
