Skin, hair, fingernails, toenails. Imagine a world if evolution decided to make it so skin didn't regenerate anymore? Or if our hair stopped growing after it was cut or lost in an accident. Recall all those moments in your life that your hair was cut/ripped out and if that hair didn't grow back, what your head would look like now??
If there were humans that were "phased out" because of their regeneration ability, it was probably because they didn't have the science/technology to stop the immediate trauma of the lost limb. So they quickly died before their body had the time to regenerate (bled to death). Hence, this species of humans wouldn't have had the quantity and lifespan to properly gain a foothold in the history of humans.
