Ich vermute natürlich Körperbehaarung. Wir haben keine wirkliche Verwendung für Körperhaare.
Vielleicht Zehennägel.
Im Allgemeinen wird die menschliche Spezies wahrscheinlich körperlich schwächer, da die meisten Menschen im Alltag nicht viel körperliche Kraft aufwenden.
Das Sehvermögen des Menschen könnte kürzer werden. Wir müssen jetzt schon keine großen Entfernungen mehr sehen. Unser Sehvermögen ist von Hindernissen umgeben. Für andere Dinge haben wir Sensoren.

The problem with this is evolution is done mainly going to happen through natural selection. These traits don’t really have any impact on reproductive success, in fact, reproductive success doesn’t really seem to be a huge issue for humanity in general. So something „Useless“ can be carried on for.. well.. ever? At least until civilization collapses.
If current trends are anything to go by then actual evolution of our species will no longer continue beyond modern times. Genetic modifications and mechanical enchancements will continue to outpace to the point where it can no longer work in a meanigful way as those things happen to timescales much shorter than a generation while evolution works on timescales which surpass it by orders of magnitude.
One thing to keep in mind is very few things are “useless”.
People used to think the appendix was useless until we figured out it is basically a backup drive for gut micro flora
Body hair helps with capturing scents and hormones our body produces, which can subconsciously impact mating selection
