Micro evolution + micro evolution = macro evolution

hmmmmm

to me micro is more like walking next door

and macro is like teleporting there.

A paleontologist friend of mine has studied the hollow spaces inside the bones of theropods pretty extensively, though, and this theory is what he arrived at based on that.

Aggie, I can't rep you for some reason but I would if I could. Great, great post showing the logic (or lack of) of the creationist side.

Is he by any chance the guy who published this in Nature?

I’m so glad that YECs at this forum are able to engage in such thoughtful, mutually constructive debates.

If you’re going to reply again, please read my post carefully and specifically address the point I’m making in it. Why can’t small changes add up into large changes, as appears to have happened in the transition between dinosaurs and birds?

I don’t think so. The paleontologist who I discussed it with is the curator of the New Jersey State Museum, where I worked for a little while before I started college. I’d rather not give out his name, since he already has a bit of a problem with the quantity of spam e-mail and unsolicited phone calls he receives, but he’s the person who Mr. Pardalis in my comic series is based on.

I’m also pretty sure that the time when I discussed this with him was quite a bit longer ago than 2005, which is when the article you linked to was published. But I guess it’s possible he described his idea to someone else, and they ended up researching it and publishing it on their own.

Because it violates Scripture.

All these small things adding up into big things is not how the Creator of the universe operates.

In fact --- thanks to Adam --- just the opposite occurs.

That would be a bit of a flawed comparison because teleporting doesn't actually consist of walking.

The main point here is that the macroevolution is just a continuation of microevolution - heritable, genetic changes within a population operate on the exact same mechanisms whether it's a slight genetic change, a single speciation event, or a clade's billion-year-long evolutionary history.

The creationist mantra of "micro, not macro" is like saying that planes can fly across the state or across the country (depending on the creationist) but not across the world.

Thank you for this admission. No beating around the bush, no vague terms or hiding behind a veneer of science, just straight up "It's against my religion". If only other creationists were as straightforward, the crevo controversy would have been over long ago.

then all macro is micro but all micro isn't macro?

yeah but you already know about planes. nevermind.

Why can’t small changes add up into large changes, as appears to have happened in the transition between dinosaurs and birds?

The crucial thing to understand is that small genetic changes can accumulate into large genetic changes down the road - macroevolution is a function of microevolution.

Microevolution can be contrasted with macroevolution; which is the occurrence of large-scale changes in gene frequencies, in a population, over a geological time period (i.e. consisting of lots of microevolution). The difference is largely one of approach. Microevolution is reductionist, but macroevolution is holistic

But scientists who find themselves unable to explain the behavior of their systems from the properties of elements may falsely call upon holism even if the system in question happens to behave completely in accord with a conceivable (but unseen) statistical explanation.
