The Science of Biological Evolution (no politics or religion)

A thought just struck me but it seems rather far-fetched. If food was in short supply for many years, maybe shorter people need less food and are more likely to survive starvation. They used to reckon that in the second world war there were Japanese who survived in jungles on islands in the NW Pacific on about two leaves per day. Seriously.
Good god...please stow that stereotype. Do you also think they hid inside hollow trees unmoving for weeks waiting to bayonet some passing soldier while yelling "Banzai!"? You've seen too many John Wayne movies...or read too many Beano's picture books extolling the virtues of the British Army.

The 15 and 12 year olds are outdoing you on the maturity level here.

No, genetic evolution implies genetic change but it takes many generations for old genes to be lost. There can be reversions .... some call them throwbacks. Take my late mother for instance. She was born in 1924. If you look at a photo of her class at school, they're all very obviously white. Really obvious, except my mother. She looks like ... I don't know, maybe Lebanese or Italian. Darker skin than all the others and very dark, very curly hair. I was blond when I was very young and my late younger brother was blond all his life. Later in life my mother lost that dark tint to her skin entirely. Now, I was in Afghanistan in 1976 and I'd been in India for 5 months. Most of my clothes had worn out and I bought clothes in Kashmir and India so I was dressed like a native. I was walking into a city called Herat and some cars passed me. I checked in at a hotel and was approached by the people who were in those cars. They'd seen me on the road and they were convinced I was Afghan. I tan easily.
That was written partly to wind someone up.
So called "evolution". Like when wolves became dogs, that's adaptation to they're environment over time, encouraged eventually by purposful breeding. You can't turn dogs back into wolves, you can't turn house cats back into big wild cats. though it would seem that if 'evolution' worked the way it supposedly does, shouldn't that happen?

How about the evolution of this thread?

So called "evolution" is different from adaptation. Like when wolves became dogs, that's adaptation to they're environment over time, encouraged eventually by purposful breeding.

Yeah, that could happen... but the changes are small and random, so it'd be very unlikely.

But... you say this with what proof, exactly?

Why on Earth would you think that dogs and cats could not be purposefully bred back into wolves and big cats over time?
