Actually, might only be a 200-300,000 year old event based on mtDNA research.
The time period was just anm example.
You got Refuted on the main point.. that there was even fusion that made One species into Another, and there was nothing that really needed a god. It was a mutation.
The time period is based from mitochondrial DNA; mtDNA/mDNA and research into human origins;

The study's lead author, Rebecca Cann, called her colleagues' and her choice to use Eve as the name "a playful misnomer," and pointed out that the study wasn't implying that the Mitochondrial Eve wasn't the first -- or only -- woman on Earth during the time she lived [source:
Cann]. Instead, this woman is simply the most recent person to whom all people can trace their
genealogy. In other words, there were many women who came before her and many women who came after, but her life is the point from which all modern branches on humanity's family tree grew.
When the researchers in the 1987 study looked at samples taken from 147 different people and fetuses, they found 133 distinct sequences of mtDNA. A few of the people sampled, it turned out, were recently related. After comparing the number of differences among the mtDNA samples within races, they found that Africans have the most diversity (that is, the most number of differences) of any single racial group. This would suggest that the mtDNA found in Africans is the oldest: Since it has had the most mutations, a process which takes time, it must be the oldest of lineages around today.
The two distinct branches they discovered contained the mtDNA found in the five main
populations on the planet: African, Asian, European, Australian and New Guinean. Researchers found that in the branch that was not exclusively African, racial populations often had more than one lineage. For example, one New Guinean lineage finds its closest relative in a lineage present in Asia, not New Guinea. All of the lineages and both of the two branches, however, can all be traced back to one theorized point: Mitochondrial Eve.

According to DNA research, we may all have a common ancestor, an African woman who lived thousands of years ago. How did scientists reach this conclusion? Is it even possible?

I think you've confused something, either in translation or comprehension, regards my being refuted; as I'm not denying the fusion in human chromosome happened, only questioning the method by which it would have occurred, and/or why. Also "when" along the chain of proto-humans did such happen. So far the links provided show what and where this fusion occurs, but don't describe what the natural process would have been to make it happen.
That it is a mutation is clear, and I don't dispute it. I'm neither a Creationist, nor a Darwinian/Evolutionist on this matter about humans branching of from the simian tree, might be closer to a supporter of Intervention Theory (though might pick a couple of nits with Pye);

Going further on the subject of mutations, consider the case of one such caused by human 'intervention', that of the mule;

A
mule is the
offspring of a male
donkey (jack) and a female
horse (
mare).
[1][2] Horses and donkeys are different species, with different numbers of
chromosomes. Of the two
first-generation hybrids between these two species, a mule is easier to obtain than a
hinny, which is the offspring of a female donkey (
jenny) and a male horse (
stallion).
The size of a mule and work to which it is put depend largely on the breeding of the mule's mother (
dam). Mules can be lightweight, medium weight or when produced from
draft horse mares, of moderately heavy weight.
[3]:85–87 Mules are reputed to be more patient, hardy and long-lived than horses and are described as less obstinate and more intelligent than donkeys.
[4]:5
...
Mules and hinnies have 63
chromosomes, a mixture of the horse's 64 and the donkey's 62. The different structure and number usually prevents the chromosomes from pairing up properly and creating successful embryos, rendering most mules
infertile.
A few mare mules have produced offspring when mated with a purebred horse or donkey.
[18][19] Herodotus gives an account of such an event as an ill omen of
Xerxes' invasion of Greece in 480 BC: "There happened also a portent of another kind while he was still at Sardis—a mule brought forth young and gave birth to a mule" (Herodotus
The Histories 7:57), and a mule's giving birth was a frequently recorded portent in antiquity, although scientific writers also doubted whether the thing was really possible (see e.g.
Aristotle,
Historia animalium, 6.24;
Varro,
De re rustica, 2.1.28).
As of October 2002, there had been only 60 documented cases of mules birthing foals since 1527.
[19] In
China in 2001, a mare mule produced a
filly.
[20] In
Morocco in early 2002 and
Colorado in 2007, mare mules produced colts.
[19][21][22] Blood and hair samples from the Colorado birth verified that the mother was indeed a mule and the foal was indeed her offspring.
[22]
A 1939 article in the
Journal of Heredity describes two offspring of a fertile mare mule named "Old Bec", which was owned at the time by
Texas A&M University in the late 1920s. One of the foals was a female, sired by a jack. Unlike her mother, she was sterile. The other, sired by a five-gaited
Saddlebred stallion, exhibited no characteristics of any donkey. That horse, a stallion, was bred to several mares, which gave birth to live foals that showed no characteristics of the donkey.
