Your welcome.They're inter-fertile, true, but there is no real evidence definitively proving we all originated from the same place; there could be several origins around the planet. Genetics, and genetic codes, are environmentally dependent by the very nature of the planetary environment itself, hence the differences in adaptations that do no appear to change quickly, or at all.Good post Actually black people are usually various shades of brown, and white people are never pure white. But, yes, as anthropologist Ashley Montagu showed in his book "Man's most dangerous myth - the fallacy of race" he shows that all races are related and that the variance within so-called races is usually greater than the variation of races.
Also a possibility. It's just not one I buy at the moment; I think the different peoples formed at different places, and I base this on the obeservation of the 'Out Of Africa' myth; if that were truly the case, then Africa would be now be the home of our most advanced and healthy and technically competent demographics . They aren't.I think that was the book where I learned 'Peking man" had a similar skull size and structure to that of the Vedda of Sri Lanka (Ceylon) Genetic studies have long shown all races of man have a common origin in harmony with what the Bible actually teaches, e.g.:
Acts 17:26 (NW)
And he made out of one man+ every nation of men to dwell on the entire surface of the earth,+
More recently, studies have shown that all races also come from one woman - the mitochondrial Eve, and from one man - the y-chromosomal Adam.
You are correct that the molecular clock is not reliable at all - so I disregard the dates and stick with the actual genetic research when I am researching this subject:
First from our literature giving the basics of this genetic finding:
This is an authorized Web site of Jehovah’s Witnesses. It is a research tool for publications in various languages produced by Jehovah’s Witnesses.wol.jw.org
"In recent years, scientists have researched human genes extensively. By comparing human genetic patterns around the earth, they found clear evidence that all humans have a common ancestor, a source of the DNA of all people who have ever lived, including each of us. In 1988, Newsweek magazine presented those findings in a report entitled “The Search for Adam and Eve.” Those studies were based on a type of mitochondrial DNA, genetic material passed on only by the female. Reports in 1995 about research on male DNA point to the same conclusion—that “there was an ancestral ‘Adam,’ whose genetic material on the [Y] chromosome is common to every man now on earth,” as Time magazine put it. Whether those findings are accurate in every detail or not, they illustrate that the history we find in Genesis is highly credible, being authored by One who was on the scene at the time."
The following source is off on the dating (molecular clock) but accurate on the genetics:
"In the field of human genetics, the name Mitochondrial Eve refers to the matrilineal most recent common ancestor (MRCA) of all currently living anatomically modern humans, who is estimated to have lived approximately 100,000–200,000 years ago. This is the most recent woman from whom all living humans today descend, on their mother’s side, and through the mothers of those mothers, and so on, back until all lines converge on one person. Because all mitochondrial DNA (mtDNA) generally (but see paternal mtDNA transmission) is passed from mother to offspring without recombination, all mtDNA in every living person is directly descended from hers by definition, differing only by the mutations that over generations have occurred in the germ cell mtDNA since the conception of the original "Mitochondrial Eve". "
Note, however, the assertion (with zero proof) that there were other mothers before the mtDNA Eve. This is based on the assumption that the previous mother had only one daughter. This is very unlikely since the population was lower and large families would have been more likely. e.g Genesis 5:4 states Adam and Eve had plural daughters.
Concerning the Y-chromosomal Adam:
A pair of genetic studies has pushed back age of men's most recent common ancestor.www.sciencenews.org
Y chromosome in descendants of one human male In human genetics, Y chromosomal Adam ( Y MRCA) is the theoretical most recent common ancestor (MRCA) from whom all living people are descended patrilineally (tracing back along the paternal lines of…enacademic.com
"In human genetics, Y-chromosomal Adam ( Y-MRCA) is the theoretical most recent common ancestor (MRCA) from whom all living people are descended patrilineally (tracing back along the paternal lines of their family tree only)."
"In human genetics, the Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living males are descended patrilineally. The term Y-MRCA reflects the fact that the Y chromosomes of all currently living human males are directly derived from the Y chromosome of this remote ancestor. The analogous concept of the matrilineal most recent common ancestor is known as "Mitochondrial Eve" (mt-MRCA, named for the matrilineal transmission of mtDNA), the most recent woman from whom all living humans are descended matrilineally."
Thanks for the links; I'll give them a read later; and as said earlier, if they're going to teach' evolution' as fact, I have no problem with them teaching the above also. I would rather they not teach either as 'fact', personally, just as possibilities and philosophy.
Please note that there is a plethora of genetic evidence that all 'races' of man come from:
1. A common origin
2. from the y-chromosomal Adam (Acts 17:26 - one man)
3 from the mitochondrial Eve.
