Can microevolution exist without it "adding up" to full on evolution?

Question

Wouldn't that be like admitting that letters exist, but that they cannot make words?

Answer 1

I believe there is scientific support for both, and micro-evolutionary change can and has resulted in macro evolution (or the formation of new species...)But while macro evolution ("evolution") logically implies micro evolution, the reverse is not necessarily true. That is, micro evolution HAS to happen for evolution to take place, but the evolution of new species is not necessarily a result. Other factors (such as geographical isolation or environmental change) are present for macro evolution to happen. Macro evolution happens when new species are formed. So micro evolution could, in theory, exist without "adding up" to the formation of new species...That said, however, the gradual (and not so gradual) appearance of new species is evident in the fossil record and a logical result of microevolution as adaptation into new niches.

So a person that believes in micro evolution but not in "full blown" evolution is maybe more like...saying letters exist but you cannot make NEW words or new languages with them ...

Answer 2

What I think is right now in this century or millineia, we cannot really tell that we are evolving, BC. Only 1,000 years does not show much drastic changes in evolution happening, but compared to 1,000,000 years, then we can "see" what evolved and how far we evolved. E.g.'s.....

1,000 years could possibly show that we evolved by having taller babies. I did notice that men from 1,000 years ago are about 5'4", 5'6" being the tallest......and many women are about 5'5" to 5'7" being average today (with exceptions)! While I agree that good nurtrition is a big part of this, I also think that's part of evolution, too. Better nutrition does give evolution a boost, imho.

1,000,000 years could show---if only slightly----our brains changed, the shape of our skulls changed, etc. That takes a lot more time to evolve for us to notice any drastic changes, whereas height takes less time for us to notice any drastic changes.

Answer 3

But letters exist to make words, anyways... Sure, why not. One thing that evolution has not been able to predict is the creation of new gene material (like a new chromosome).

Answer 4

Evolution theory is just a misconception. Due to genetic stability, there is a law of constancy of species. Either macro or micro evolution, they are fictions. Teaching evolution as fact is a lie!

Answer 5

If micro evolution keeps happening it will gradually become a full evolution after so many years. It will add up after some time, right! You can never say its not happening. It does happen and its happening.

Answer 6

oximoron??
