But we might develop opposable thumbs because our level of intelligence allows us to begin using tools. I wouldn't say it has no bearing. As for the the tail part...don't be so sure. Ever hear of genetic engineering?
No, i'll say we need opposable thumbs first, then we began using tools. And opposable thumbs isn't so much about intelligence as about technology.
I thought the ability to roll the pinky-side of your hand inwards(like touching your pinky to your thumb) and grasp things was a bigger evolutionary step than opposable thumbs.
That's just the impression I got from the admittedly very little I've read on the subject. 🙂
Pinky finger? I know lots of people who had their pinky finger choppped off (that's what happens when you owe gambling debts to Asian people), and they function just fine... now try living without opposable thumbs... try to hold a fork, spoon, use a hammer, hold a book, etc.
