We can build stuff and have AM...and make grilled cheese sandwiches.
How do the qualities you cite have anything to do with the evolution of current day humans? What writings have apes done with their toes?
Because science.
Actually we can write with our toes too, it is just a matter of practice. I saw a TV show with a Thalidomide girl, One thing they showed was how she could write without arms.
Maybe in 50 Years voice activation will work well enough so we just have to say what we want the computer to write, It is not that far a reach, even today we have people talking out of their derriere.
They can use their toes for brain surgery too. Too bad they are incapable of operating.
maybe cause we didnt evolve from them
