why do we not see evolution in humans?

[the_gloaming]

im really not sure how skin color originated, mutations probably, but i still consider that micro evolution.

That's fine with me. In the original post you didn't discriminate between micro and macro, and of course in humans micro evolution is all you will find evidence for in a period of 6,000 years. So have you conceded evolution (even if it hasn't resulted in a new hominid species) has occured over the past 6,000 years ?

Viral infection is a mechanism for sickness..... in theory. What's your point?

hah, way to jumble context

evolution that does not refute creation - yes

What context? You were drifting into the "It's only a theory" argument.

 

[brightlights]

some theories are much more established than others. gravity, btw, is a law

Is it now? And what exactly is the "law" of gravity?

 

[Nathan David]

in theory

And the theory has been validated by loads of evidence.

But that's beside the point. What you described with the development of darker skin is evolution: a change in the characteristics of a population over time. If darker skin can become prominent in a population because it confers a survival/reproductive advantage, what's to stop any other trait from becoming prominent in a population?

i dunno, barriers between species?

You do know that was disproved about a hundred years ago by Einstein, right?

What causes said barrier?

What are those barriers?

[woops, crossposted with ForeRunner. I gotta go for the weekend anyway.]

What causes said barrier?

try to pregnate a female ape with human sperm

There have been reports of the reverse.

There have been reports of the reverse.

really? legitimate ones?

 

[ForeRunner]

I curious about this too.

 

[Tachocline]

Legitimate probably not. Let's face it, that's a very touchy subject. But there have been reports. The famous case of a chimp called Philip I believe turned out to be false on DNA examination (though he looked mixed) but there have been other reports over the years.

Ans let's also fact the fact that no matter how taboo it would be I am sure someone has tried or will try it.

To sum up I would doubt the veracity of the claims but it is something that has been alleged.

After reading through this entire post, my faith in christianity has just shot up through the roof. I don't think people really know what they are talking about on this thread, but come on, I want to see something that brings us from a single cell organism to what we are today.

You talk about us getting bigger and our skin color being darker, that is not evolution, it is adaptation, evolution is:


A change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species.


Tell me, when has one species developed into another species?
