Evolution: the basics

[Little Dragon]

Bur he never used the term 'evolution' even once in his book.

That's the process he had discovered, nomenclature aside.

Okay, but that is not the same thing at all. They are merely identifying populations that split off from the original YC Adam and M Eve. Odds are that neither Y Chromosome Adam or Mitochondrial Eve had that many children. And neither one would have known the other.

Why would they have known each other?

Why would they have known each other?

I said that they would not have. Many Christians think that they lived at the same time and were a couple. That is highly doubtful. They almost surely lived at different times and even if by some weird odds there would still have been many thousands of humans living and there was no guarantee that they were together.

"But geneticists, by tracing the DNA patterns found in people throughout the world, have now identified lineages descended from 10 sons of a genetic Adam and 18 daughters of Eve.

The human genome is turning out to be a rich new archive for historians and prehistorians, one whose range extends from recent times to the dawn of human existence."

The Human Family Tree: 10 Adams and 18 Eves (Published 2000)

Scientists, by examining DNA patterns that are inherited maternally or paternally, can trace human lineages back to original branches, or sons and daughters, of a genetic Adam and Eve; book of Genesis mentions three of Adam and Eve's children: Cain, Abel and Seth; but geneticists, by tracing DNA...

Let's look more closely at Y chromosome Adam and Mitochondrial Eve. Basically Geneticists have shown that all humans alive have descended from one common man who lived about 270,000 years ago that they have dubbed Y chromosome Adam. And all humans alive have descended from one common woman who lived some 200,000 years ago, which they have dubbed Mitochondrial Eve.

The first thing to note is that these two individuals where alive 70,000 years apart. IOW they were not a couple.

The second thing of note, is that saying that Y chromosome Adam is our common ancestor is not the same as saying he was the first human. It could be his father was the first human. Or his great great great grandfather. You get the idea.

It is easier to prove that all humans descended from one couple of humans that proving that diferent species share a common ancestor.

There is no evidence that all humans descended from a single COUPLE. Y chromosome Adam and Mitochondrial Eve lived some 70,000 years apart.

Homo sapiens has blended with other species, we have neanderthal DNA us Eurasians. So we have at least 2 sets of genetic Eve, and I doubt either had ever met.

What a waste of time typing that.

Even the idea of there being a "first human" is just wrong. There is no one clear trait that makes a person a human being. When modern humans began is more of a judgment call than anything else. As the saying goes, populations evolve, not individuals and one paleontologist may cite one important trait and another will have a different one.

Aside from their genome and number of chromosomes? Not much physiologically no.

And we do not know when the two chromosomes joined. That may be understood in the future. But it is possible that Lucy had only 23 pairs of Chromosomes too.

Absolutely!!!!! You have to grant me a bit of slack for the way I wrote my post. I basically dumbed things down so that my two points would not become too complicated.

I'll have to see if I can find it, but there is a molecular biologists that is pretty certain he has genetic evidence for another Homo species in our lineage that is previously unknown.

Maybe Denisovans?

Mitochondrial Eve only checks one's line of descent through a purely matrilineal line. Though we do have Neanderthal DNA in us it appears that there are no direct lines left that trace only through a purely matrilineal line to those women.

Both Y Chromosome Adam and Mitochondrial Eve only check our heritage through either a purely matrilineal line of descent or a purely male line of descent. So somewhere along the lines there were males with Neanderthal DNA that we descended from. And female. If you think about it for the number of ancestors that you have keeps doubling for quite a few generations before they start to repeat.

Yes, his observed and recorded the evidence. The term used in alchemy at the time was transmutation.

Gradation through generations over time.

Why would they have known each other?

To...make genesis true?

I think there was miscommunication earlier on in this thread. I've decided to abandon the line of discussion I was involved in.

Interesting. I would be surprised if there wasn't a whisper of Homo erectus DNA in modern humans, Given that erectus was around and had been around for a very long time, a very successful species. Erectus. Funny name too.
