yes.only if wen it has healing property

Answer 2

It is quite possible.
Healing depends on person to person. Part of cell end probably known as telomere determines the speed of cell regeneration. It can evolve for faster regeneration over time.
You could remember every single thing in your life. Certain psychological conditions allows this. For e.g. Stephen Wiltshire.
We are already adapting to hard climate changes. And unfortunately forcing other animals to adapt or die too.
Become super genius. That's a relative one, and depends on your definition of genius.
Can control every cells change. We do control them but involuntarily, it would be dangerous if we had to control each cell by thought and we messed up like forgot to excrete or something, we could end up dead. So automatic systems, like the way they are.
Changing body shape, that will make our bodies fragile, so that's an. Evolutionary stage I would rather condemn.
