Bacteria surviving environmental changes is evidence of natural selection, because there's clearly something hartier about the bacteria that survive than the bacteria that don't, but it'snot evidence for evolution.......anymore than faster monkies being able to get away from lions and breed fast monkey babies is. It's evidence of survival of the fittet, but not evidence that an animal can mutate to become fitter than they already are.
Most "evidence" for beneficial mutations fall into tis category.

But that's microevolution.......one monkey being able to run faster from a lion than others isn't a mutation which changes the organism....... how is that evidence for macroevolution?

Re: micro - macro
Ned, I suppose micro-evolution would be under the level of species.

Re: micro - macro
What mechanism is there that stops a lot of smaller changes cummulating in a totality which is a larger change?
I've heard that a lot of changes that life goes through to adapt to environment aren't really new mutations but activations of recessive genes........

Re: micro - macro
Can you give us an example so we can go from there?
I've heard variation of color in plants and animals in adaptation to environment isn't caused by new mutation.

Re: micro - macro
Ned, different species can't produce fertile offspring with one another, correct? Therefore, at that time, the genetic destinies of the original animal and the newer evolutionary form have become mutually exclusive.......I'd have to say that's definitely macroevolution.
But is there any evidence for it occuring?

Re: micro - macro
Contrary to this (and despite Crash and Lam playing dumb), micro-evolution is no evidence for the unlimited variablity of living things.

Re: micro - macro
Loudmouth, but if the people haven't mutated, then they haven't evolved, right?

Re: micro - macro
Can you give me proof that this animal's existance was caused by evolution?
