Macroevolution would require the addition of genetic material; natural selection does not, relying on existing genetic material in the population. You should know this already.
I do bones, not genetics.
Are you saying "macroevolution" cannot occur? If that is so, what is the magic barrier that stops lots and lots of micros from forming a macro?
Mostly, but not necessarily. You are confusing two issues.
... natural selection does not, relying on existing genetic material in the population.
Again, the mechanism of evolution (macro- or micro-) is variation and selection. Now, don't you feel like a drooling doofus?
You should know this already.
You should get to square one before posting again.
