: I was hoping for something more concrete like how
: Einstein's theory predicted the sun would bend star light.
Natural Selection is just as concrete and just as observable. There are even mathmatical formulas involved if that is what you need.
: There are many species currently under stress. Often
: they die out. Can anyone predict what adaptions they
: will make to survive?
Yes. But unless those adaptions are made they may not. There is a BIG difference between experimentation and predictability of scientific theories and foretelling the future. Astromony, for instance can predict where a known planet will be at a given time in the future using certain known assumptions. Astronomy can't predict when a currenly unknown asteroid will collide with the earth.
: Your answer sounded like "An organism will pass its mutatated
: genes to its offspring". Big deal. I know variation happens but
: is this proof by induction that humans evolved
: from a chimp-like ancestor? I don't buy it.
Then you should do a little more digging into paleontology, genetics, and phylogeny. Your original question had nothing to do with human ancestory.
: That's interesting. I'll look around a little. If you happen to have a URL, pass it on.
Next time you go to the doctor for an antibiotic or vaccination you can experience the experiment first hand.
: Would you share one example? If it sounds good, I'll look at the book.
I'll list a few that have been observed first hand...
European house sparrow
Rhizosolenia (this is clear from the fossil record rather than first hand)
the salamander Ensatina species E. oregonensis has split
the famous peppered moths can completely change color when the environment changes within a couple dozen generations
mosquitoes and DDT
Sickle-cell anemia victims (condition caused by evolution defense against malaria)
There are countless others that have been modified non-naturally (ie, humans do the selecting) like dogs, pigeons, flowers, etc. New species of orchids are produced at a rate of about 300 a month!
: That's why I compare it to evolution. There is a ton of
: evidence for evolution but little proof.
Is there little proof or have you just not looked?
: I'd be happy with proof that
: we have a common ancestor with chimps and for me that
: requires a repeatable, verifiable experiment;
: not just a trail of fossiled bones (although this
: is very compelling evidence)
I'd like to get proof that the civil war really happened. I don't think that we need to repeat history to see that history did in fact occur. The evidence for evolution is more overwhelming (if you look for it) than the history of the civil war.
