There are birds in the Pacific which have been discovered to adapt (as in evolve within a few generations to use different food sources as El Ninó comes and goes and changes the ocean temperatures..(can't remember the details right now)...These birds are not 'teaching' their young, they are physically altering their DNA in small areas.

You must understand, Two Bears, that most macro-evolution, as you call it, takes many thousand and even millions of years to make significant changes. We don't just send National Geographic out to take pictures of it.

....and I beg to differ..'critical mass' is just not the correct concept to describe what species like the Japanese Macaques do in learing new behavior. These monkeys are simply learning, like children......but their preceeding evolution equipped them with the more advanded brains necessary to learn this way. Chimps and Bonobos and Orangs..etc. do similar things, because their DNA is over 90% identical to humans!. Several million years ago, there was ONE common ancestor, and anthropologists are honing in on it as fast as they can dig! *grin*

DNA lines are being traced and amazing discoveries are being made every day...some DNA lines in the Neanderthals from the Caucasus Mts. are proving that Neanderthals are NOT direct ancestors of humans, but represent a branch of primates that didn't make it......and at the same time, some human DNA has been traced back 20-30 thousand years..(I believe the Basques, in Spain, have some very ancient lines)

This stuff IS 'macro-evolution', on a very long scale...we are discovering where we came from, and sadly, it upsets some folks. It is interesting and useful, but what we ARE now is what is really important.
