So as I understand it we have some difference of opinion about thumb lengths, right?
You suggest your thumb is much shorter than your fingers. Anatomists say human thumbs are long. When I measure my thumb and fingers I find my thumb to be long.
There is a difference and your answer is: "Yeah, I knew you couldn't tell one from another." It sounds like you don't like where this is going.
So where are we? Are human thumbs long compared to other primates or not? How long is your thumb compared to your longest finger?
