Not humans specifically but one of my favorite quirks of vertebrate evolution is the recurrent laryngeal nerve that loops around the aorta and goes back up to the larynx[1].

In giraffes that nerve is several meters long.

Came here to say just this.

Another interesting one is the auricular tubercle[1], where the genetic trait of a "pointy" ear found in other mammals reappears in some humans.
