Science Vs. Christianity

[HeIsRisen2018]

Yes, but the Theory of Evolution says we started as microbes billions of years ago and slowly evolved into what we are today. Do you honestly think that is what God did?

No. I always took that to mean that God used them as building blocks when He created Adam.

You don't know how close you really are. Biologists believe that the modern eukaryotic cell- which we are all made of- evolved when simpler single-cell organisms decided to form bigger cells by banding together as organelles and surrounding themselves with a protective membrane. One of the organelles was declared leader (the nucleus), while others had other specific functions (mitochondria were the energy plants, Golgi bodies did the food processing, etc.).

Whoa there, those ancestral single-cell organisms were not human, early or otherwise. Human = member of genus Homo. Modern human is the species Homo sapien.

The next question is when did that happen? When did the species we know today become reality?

It is my understanding that a species is separated by its ability to procreate. At the moment when homo sapien became a separate species it would not be able to procreate with its parent because it would no longer be of the same species. That's a pretty major jump.

 

[KevinK]

Estimates vary, anywhere from 300,000 to as much as 800,000 years ago that modern humans speciated from the genus Homo. Call it about a half-million years ago. The first Homos, i.e. humans, emerged some 2 million years before that.

The definition of species is correct. Something is a different species when it cannot mate and produce viable offspring. In the case of modern man, that took about two million years.

Why not, though? We currently all start as pairs of single-celled organisms. It now only takes nine months until we're fully-differentiated vertebrates, not three billion years like the first time.

But that's my point. At the moment when mankind became a new species it would have been incapable of procreating with its immediate ancestor. It would be like my wife and I bearing a child that was a new species, incapable of interbreeding with either of us. Now, for this new species to continue, it would require a second of the opposite sex at the same time or at least within a couple decades and within the same geographic location in order to find each other.

 

[KevinK]

OK, I see your point. How about this then: species differentiation is coded by a recessive gene, which gets passed on silently to successive generations until there is enough frequency for double-recessive matings to occur? The double-recessive offspring can not mate with the previous generation, but can successfully mate with other double-recessives?

They would still have to be in the same geographic location on this ball called earth in order to find each other. If they don't, natural selection dictates that the gene you speak of would get bred out of existence.

 

[KevinK]

I don't necessarily see geography as an issue. Any inbreeding population can potentially support recessive genes, or we wouldn't have recessive genes today.

If I can chime in,
We see through natural selection that the genetic diversity actually takes a loss. For example, the Wolf has enough genetic diversity that you can breed it down to a poodle. However, each time you breed it down, it looses genetic diversity. In short, you can't breed a poodle up to a Wolf because it doesn't have the information within its DNA. In simple terms, that DNA information was removed through natural selection. In no cases do you find the addition of information in DNA through natural selection. It's always an overall loss of diversity.

In the same way, a single cell egg from your mother had the complete informational DNA set to develop into a human in 9 months.

What I'm getting at is this, a dog will never mutate into a bird or any other animal like a squirrel, rat, lizard or cat because to my understanding, mutations and natural selection causes a loss in DNA information.

In the same way, a single cell can only grow within the information contained within its DNA and through each mutation or natural selection, that information pool is diminished.

P.S. that's why we don't marry our sisters or cousins...
