The ice ages started about 2.6 million years ago, so this does not pre-date most of the ice ages. And this does not pre-date our 'monkey' ancestors. It does not even predate Homo Erectus. And our 'monkey' ancestors never existed. We are related to the great apes, not monkeys. And diverged from them millions of years ago.
I suggest you do a bit of research before displaying such massive ignorance concerning the human line of evolution.
Hey --------
Did I say or CARE when the Ice Ages STARTED?? No I didn't.. I put 400,000 BCE into perspective. The LAST couple of the glacial periods being much milder than the previous ones..
That 200,000 yr difference is SIGNIFICANT. Because previous knowledge was based on Homo Erectus being the first early hominids to migrate from Africa to Northern Europe and Asia about 60Kyrs ago.. But BEFORE THAT happens -- about 200,000 BCE the first DISTINCT human species emerged from these indigenous species of the icy North..
Lemme clue into what the OP is about..
BEFORE modern-looking humans spread worldwide from Africa more than 60Kyrs ago.. Born from the Ice Ages --- not the plains of Africa..Discovery of Oldest DNA Scrambles Human Origins Picture
New tests on human bones hidden in a Spanish cave for some 400,000 years set a new record for the oldest human DNA sequence ever decodedand may scramble the scientific picture of our early relatives.
Analysis of the bones challenges conventional thinking about the geographical spread of our ancient cousins, the early human species called Neanderthals and Denisovans. Until now, these sister families of early humans were thought to have resided in prehistoric Europe and Siberia, respectively. (See also: "The New Age of Exploration.")
But paleontologists write in a new study that the bones of what they thought were European Neanderthals appear genetically closer to the Siberian Denisovans, as shown by maternally inherited "mitochondrial" DNA found in a fossil thighbone uncovered at Spain's Sima de los Huesos cave.
"The fact that they show a mitochondrial genome sequence similar to that of Denisovans is irritating," says Matthias Meyer of Germany's Max Planck Institute for Evolutionary Anthropology in Leipzig, lead author of the study, published Wednesday in Nature.
"Our results suggest that the evolutionary history of Neanderthals and Denisovans may be very complicated and possibly involved mixing between different archaic human groups," he said.
Neanderthals and Denisovans arose hundreds of thousands of years before modern-looking humans spread worldwide from Africa more than 60,000 years ago. The small traces of their genes now found in modern humans are signs of interbreeding among ancient human groups.
Don't know what you are trying to prove here, other than your profound ignorance concerning the evolution of humans.
Homo Erectus Colonization in Europe - Pakefield Homo erectus in England
The Oldest Homo Erectus
The oldest known Homo erectus site outside of Africa is Dmanisi, in the Republic of Georgia, dated to approximately 1.6 million years ago. Gran Dolina in the Atapuerca valley of Spain includes evidence of Homo erectus at 780,000 years ago. But the earliest known Homo erectus site in England prior to the discoveries at Pakefield is Boxgrove, only 500,000 years old.
Homo sap came out of Africa, the Dennisovians and Neanderthals, apparently, from Europe. And none of these groups evolved far enough apart that they could not intermix. That evidence is in the genes of modern man. All that the DNA from those bones established is that the history of our present species is a bit more complex than we previously believed. Overturned nothing, but added very interesting details.
What about Sima hominins, asswipe? Didn't you rad the article?
