Answer 2

The person above  me is wrong i got an 0%.

I don't know the actual answer but if anyone sees this yeah there wrong, have a good day, Ill come back when i find it :)

Your thumb could bend in other ways and could be moved in a 360 degrees if it was a ball and joint, if it was a pivot it could only move in a straight line and not bend like we are used too, the thumbs are opposable so humans can grab things if a different joint is used it can have a harsh affect on the human structure and functions, a major consequence is that if this evolution happened suddenly now out technology could not comprehend with this evolution and we could lose our ability to use now day tools.

this is the correct answer :)
