Skip to comments.MtDNA tests trace all modern horses back to single ancestor 140,000 years ago

For many years archeologists and other scientists have debated the origins of the domesticated horse. Nailing down a time frame is important because many historians view the relationship between man and horse as one of the most important in the development of our species. Horses allowed early people to hunt for faster prey, to wander farther than before and to create much bigger farms due to pulling plows. Now, new evidence has come to light suggesting that all modern horses, which are believed to have been domesticated approximately 10,000 years ago, descended from one mare around 140,000 years ago. The new evidence comes from a team made up of international researchers who, as they describe in their paper published in the Proceedings of the National Academy of Sciences, say that DNA evidence shows that the horse subsequently diverged into 18 different genetic lines, suggesting that domestication occurred independently in many places throughout the world.
Most other domestic animals such as cows, sheep and goats by contrast appear to have evolved from a relatively small pool, likely shortly before horses followed suit.
Interestingly, horses appear in cave art as early as 30,000 years ago, which suggests that early humans certainly knew about them and likely killed them for food for twenty thousand years before the idea of taming them came about which ultimately led to domestication...
Prior to this new research many scholars had attributed the first domestication of the horse to the Eurasian Steppes, due to fossilized evidence showing horse domestication dating to around 3500 BC. This new research will undoubtedly cause new discussions in the community as a whole which will likely lead to new theories being developed to describe how so many different groups of people came to domestic horses in so many places.

I wish I could believe stuff that the popular science folks put out, but I have become very skeptical after all the BS they have tried to sell us for the last few years.
Such magnificent creatures! Dogs also. etc..etc...
God gave us a world too wonderful to really comprehend so most of us take it for granted

The results of the latest gallop poll are in. [ rimshot! ]
Scientist view: That is such poppycock! Such nonsense! Now, see, what happened was, there was this one horse, see, and it reproduced, and then the Earth eventually had lots and lots of horses. Now, THAT'S science! Totally different from that fairy tale stuff!
Do any of the eggheads or science experts know how they date this discovery?
Since that thesis became popular scientists have found mtDNA leakage ~ from the male side. No one knows how often it happens, or how significant it is, but over a long period of time it might be quite sigificant ~ or maybe not ~ or just not discussed because it calls into question the “Out of Africa” thesis ~ see: http://en.wikipedia.org/wiki/Paternal_mtDNA_transmission
“I wish I could believe stuff that the popular science folks put out, but I have become very skeptical after all the BS they have tried to sell us for the last few years.”
Remember how, about a decade back, it was stated that all human ancestry could be traced back to a single woman in Africa?
This makes about as much sense as does global warming.
I simply don’t buy it.
The notion that horses had something to do with the evolution of humans is idiotic.
Horse riding didn't start till at the earliest 4000 BC or so, long after modern humans were fully developed. Early horses were too small to carry a full grown man for long.
Early horses could not pull heavy loads such as a large wagon or a plow. The harnesses used choked the horse, so for such purposes oxen were used instead.
Efficient horse harness for draft purposes evolved in China from about 1 AD to 500 and didn't reach Europe till about 1000.
And horses for use in plowing didn't take off in Europe till early modern times, when the Chinese (again) invention of the moldboard plow finally got there. It allowed a single horse to pull (using the collar harness) a plow.
Previous plowing methods in the heavy soils of north Europe required teams of multiple oxen, which necessitated the manorial or communal organization of farming.
I prefer donkeys...gigantenormous shaggy donkeys
The mtDNA references back to the earliest female ancestor (more accurately, the earliest one with surviving offspring).
Yes, of course.
