If you found a calculator on the Moon you would conclude it was designed. Why wasn't this same conclusion drawn when DNA was discovered? It meets all the requirements of a "technology"

I read that neadertals had brains larger than humans, and are believed to have come into existence 350,000 years ago, and gone extinct 20,000 years ago. I also read that people came into existence 130,000 years ago.

So my question is, is there a theory for why their technology developed so much slower. One would expected them to have launched satelites or gone to the moon 130,000 years after they popped into existence, like people have, given their brains. My book said they had bulgier fingers than humans. Is this what is believed to have made it hard for them to make technology?

So once again, the question is, what theories are there for why they didn't progress farther than they did?

That the occurence of biological evolution is fact, and that we have documented its occurence? Did you know that to deny the occurence of biological evolution is completely illogical no matter what your beliefs?

Did you know that the only theory involved with evolution is the process by which it occurs?

Can anyone give me some scientific evidence/proof for either evolution or creationism? I have questions and can't seem to find anyone that can prove their answer either way.

My biology teacher told us that there IS a definite answer to this question, tracing down the evolution line, but he says he wouldn't tell us unless we're still studying biology in Grade 12. Does the chicken come first or the egg?

Identical twin sisters, sharing the same DNA (confirmed by St Thomas Twin Research Unit), but I get the bunions! We both wore the same silly shoes when teenagers, so how come one of us ends up in hospital to get two ugly joints removed? Also, one has an underactive thyroid, raynods disease, gall stones and suffered a heart attack (the healthy twin who doesn't smoke, drink or consume fat), and the other doesn't. On balance, I think I prefer to have gotten away with just bunions!

How come we can be so different physically even though we came from one fertilised egg? It's not even as if we have remarkably different life styles or live in opposite hemispheres. Obviously, identical twins are not clones - but how come there are now such glaring physical differences?
