Researchers solve mammoth evolutionary puzzle: The woollies weren't picky, happy to interbreed
McMaster University ^ | May 30, 2011 | Unknown

A DNA-based study sheds new light on the complex evolutionary history of the woolly mammoth, suggesting it mated with a completely different and much larger species.

The research, which appears in the BioMed Central's open access journal Genome Biology, found the woolly mammoth, which lived in the cold climate of the Arctic tundra, interbred with the Columbian mammoth, which preferred the more temperate regions of North America and was some 25 per cent larger.

"There is a real fascination with the history of mammoths, and this analysis helps to contextualize its evolution, migration and ecology" says Hendrik Poinar, associate professor and Canada Research Chair in the departments of Anthropology and Biology at McMaster University.

Poinar and his team at the McMaster Ancient DNA Centre, along with colleagues from the United States and France, meticulously sequenced the complete mitochondrial genome of two Columbian mammoths, one found in the Huntington Reservoir in Utah, the other found near Rawlins, Wyoming. They compared these to the first complete mitochrondrial genome of an endemic North American woolly mammoth.

"We are talking about two very physically different 'species' here. When glacial times got nasty, it was likely that woollies moved to more pleasant conditions of the south, where they came into contact with the Columbians at some point in their evolutionary history," he says. "You have roughly 1-million years of separation between the two, with the Columbian mammoth likely derived from an early migration into North American approximately 1.5-million years ago, and their woolly counterparts emigrating to North America some 400,000 years ago."

"We think we may be looking at a genetic hybrid," says Jacob Enk, a graduate student in the McMaster Ancient DNA Centre. "Living African elephant species hybridize where their ranges overlap, with the bigger species out-competing the smaller for mates. This results in mitochondrial genomes from the smaller species showing up in populations of the larger. Since woollies and Columbians overlapped in time and space, it's not unlikely that they engaged in similar behaviour and left a similar signal."

The samples used for the analyses date back approximately 12,000 years. All mammoths became extinct approximately 10,000 years ago except for small isolated populations on islands off the coast of Siberia and Alaska.

Larger? And, sure, species interbreed all the time. (E.g. Muslims and goats) What was this guy smoking?

They were both Mammoths so they were not different species, they were variations of the same species.

The big question for Evolution is how does one species give rise to another species. And central to that is "what is a species?" A poodle can breed with a labrador -- no big deal, they are the same species. A poodle with a persian cat? Much more challenging.

But evolutionists like to change their thinking based on what is convenient. A mammoth breeding with a completely different species? [shrug] Sure. Why not? [/s]

I don’t the smaller mammoths had much choice in the matter as to whether they wanted to interbreed with the bigger ones.

Regarding Georgia v. Randolph, 547 U.S. 103 you should read several of the analyses done by others as well as the entire case.

In Randolph the guy lived there. The woman had clearly moved out and had, in fact, GONE TO CANADA.

If you want to apply this case to the situation in Indiana note that the woman lived there and the guy had got his stuff and moved out!

The USSC ruled in favor of the occupant who lived there ALONE ~ as would they rule in favor of the woman in this case because she lived there ALONE.

Goodness. This is one "ivory-tower" (so to speak) theory they might actually be able to test, in a sort of "Pleistocene Park" scenario:

But without being able to tell if they did breed or not (and whether the offspring were fertile), scientists can only guess whether they were different species or just subspecies. Sure a poodle and a persian cat are different species, but could a scientist tell whether a poodle and a wolf are different species with only a couple skeletal examples of each? And one might be laughed at for suggesting that a St. Bernhard and a Chihuahua are the same species just from looking at their skeletons.

Odumbo’s daddy was a rolling stone too. Banged an underage white girl, then went back to kenya to shag another married woman in his tribe. The obamas make the kennedys look like the Jetsons.

Are they SURE they were happy, rather than raped by those big, bad Columbnians?

Or, maybe the Columbian cartel was trading drugs for sex? ;-')

He's using "species" differently than is commonly understood.

Give you an example ~ salmon come in a half a dozen species that cannot interbreed. On the other hand there's a federal law regarding "endangered species" so it was determined that the salmon in each crick were a different species.

That created thousands of new "endangered species" giving enormous workloads to under-employed and under-compensated environmental attorneys.

I can only imagine this fellow believes he will get his own lawyers for free to defend each new species of extinct Mammoths he can identify.

“Listen to them. Children of the night. What music they make.”

But seriously…if they bred with this other species, and had issue, wouldn’t that mean they were actually both varieties of the same species?

Which means Panama was up and running. This means there are remnants of woollies here in Panama.

The last woollie recorded here was John McCain.

Was Georgia or Randolf the woolly? If one was Columbian, why did they move to Canada? Wouldnt prehistoric elephants hanging out at the USSC have made a more prominent news story?

One of the risks of having TWO FR boards up simultaneously is a post for one might glom over on the other one.

And as you are demonstrating, not as inappropriately as one might imagine.

I will have to think over your question though

The same thing appears to be happening with Polar Bears and Alaska Brown Bears, as sea ice is lost in the Arctic, forcing the Polar Bears to spend more time on land.
