Long Frozen DNA Shows How Humans Made Horses Faster - and
The WaPo ^ | April 27 2017 | Ben Guarino

At some point in the past two millennia — peanuts on an evolutionary time scale — humans transformed their horses into equine speed demons. Selective breeding had a price, though, beyond $30,000 vials of pedigreed racehorse sperm. Unhelpful mutations plagued the animals. The current population of domesticated horses is about 55 million, but at some point in their history, their genetic diversity crashed. The Y chromosomes of all the world's stallions are now quite similar, suggesting that only a relatively few males were the ancestors of today's horses.

Humans have not always bred so selectively, according to a study published in the journal Science on Thursday. Horse domestication began about 5,500 years ago. Ancient equestrians “were not interested in superfast animals. They were more interested in diversity and potential,” said Ludovic Orlando, a professor of molecular archaeology at the University of Copenhagen's Natural History Museum of Denmark and an author of the new study.

It started when we ate the slow ones.

Just can't not inject modern PC nostrums into anything and everything, apparently. They weren't "interested" in diversity, it was just pretty much physical reality with geographic limitations and restricted travel for most. I'd say they were most interested in docility and utility, myself.

I don't believe that any horse that is the product of artificial insemination would be considered a thoroughbred by the Jockey Club, and so would not be eligible to race at any US Thoroughbred Racetrack, and probably not at any Thoroughbred Racetrack worldwide.

I seem to remember reading many years ago that all thoroughbred race horses today descend from Nashua (IIRC). Morgan horses also have a specific progenitor. But I wouldn’t think this applies to all breeds.

Artificial insemination is widely used in horse and other animal breeding.

Interesting study is the Mongols Warrior Horses ...and Riders. Perfected riding with pitch perfect aim on their targets in full charge.

Molly the mustang is a real people friendly horse.She’s crazy fast and agile but never tries to unload me.She’s a horse that will work with you,not try to test you all the time.

The Jockey Club may issue a ‘racing permit’ for non-thoroughbreds that is accepted by state racing commissions.

I am sure they are very selective in granting this but I don’t know the details.

From Wikipedia:

Unlike a significant number of registered breeds today, a horse cannot be registered as a Thoroughbred (with The Jockey Club registry) unless conceived by live cover, the witnessed natural mating of a mare and a stallion.
So if we're talking about the fastest horses, the WaPo reporter is FOS. (No surprise.)

“suggesting that only a relatively few males were the ancestors of today’s horses.”

did the Great Flood have anything to do with it? When was that?

for non-thoroughbreds

This is the key phrase in what you posted. Some jurisdictions run Arabians, and maybe other breeds, I don't know, in separate races for that/those breed(s). But thoroughbreds only race with other thoroughbreds at any racetrack that ever runs a race in front of more than 200 people.

Or there is the possibility that the so called “junk DNA” contains all the information to revert back to the original. Wouldn’t a Creator build a backup system?
domestic hogs also revert in just a few generations.
