Skip to comments.DNA study sheds new light on horse evolution
Posted on 12/10/2009 6:28:19 AM PST by decimon
Ancient DNA retrieved from extinct horse species from around the world has challenged one of the textbook examples of evolution - the fossil record of the horse family Equidae over the past 55 million years.
The study, published today in the Proceedings of the National Academy of Sciences, involved an international team of researchers and the Australian Centre for Ancient DNA (ACAD) based at the University of Adelaide.
Only the modern horse, zebras, wild asses and donkey survive today, but many other lineages have become extinct over the last 50,000 years.
ACAD Director Professor Alan Cooper says despite an excellent fossil record of the Equidae, there are still many gaps in our evolutionary knowledge. "Our results change both the basic picture of recent equid evolution, and ideas about the number and nature of extinct species."

Some studies are dumber than others. What will be gained by the conclusions of this study??
Neigh sayer ping.
Maybe a better understanding of what is and isn't evolution.
They need to go to washington and study the asses there.
In addition to the previous comment, one thing that has been gained in these types of studies is how we can utilize the genome such as using lab animals to grow replacement organs. If you understand the genetic differences, you can compensate for them. For example, what is the genetic difference between a human and a mouse, how can we turn on and off various receptors and genes to where the mouse can grow this:
Some people like to know stuff
In contrast, ancient DNA studies have revealed that the loss of genetic diversity in many surviving species appears to have been extremely severe," Professor Cooper says. "This has serious implications for biodiversity and the future impacts of climate change."
Do stripes make me look fat?
I hear that Burger King is getting rid of their burger shots.. damn global warming.

Let’s not tempt him over here. An adult conversation on science is nice for a change.
LOL... Quite right.
Do you happen to know if there is RELIABLE genealogical lineage for Al Gore located online?
I am very curious about the Original Immigrants among his ancestors.
For instance does he descend from any Revolutionary War soldiers? How early did any of his ancestors come to Tennessee and what were their names?
Is he related to millions of living Americans, like Barack Obama, through his mom is?
It is written my son, that every scientific paper must end with these exact words. If not, you may as well forget your hopes and dreams of another grant.
I would send you an e-mail on how to do that, but the way these VRWC fanatics are leaking private correspondence and quoting it out of context is wreaking havoc with my operations here at PCU. BTW, I hope you have purged our previous correspondence.
From Old English, Gore means something like triangle. It also could have its origin in French for a glutton or lazy person.
Put in...the nation of your choice.
The climate change link must be de rigueur. Hail Caesar!
Sure. That's how I found out one of Al's recent ancestors was hung as a horse thief.
There's something genetic in that livestock angle, too. Gore's Pa, the KGB Stooge and crooked, outspoken segregationist senator from Tennessee, used to auction bloodstock cattle off to "Contributors," never deliver them, and then charge "the buyers" a "Breeding Management Fee!" Multiple corporations each "bought" (wink-wink) and each paid the yearly "management fees" (wink-wink) for the same cow or bull many times over ... at every yearly "auction." Sweet! The old man also controlled many, many tobacco allotments.
The Venona Reports are for more interesting than the Gore family tree, though. Throughout the Thirties and Forties, The KGB funneled massive payoffs to Al Gore, Sr., through Armand Hammer, the USSR's purchasing agent in the US, and KGB operative. Look THAT up.
Commie, Crook, and Racist Con man though Al's dear old dad was, not even he could have dreamed up the billion-dollar Carbon Credit scam for which Al's is the Front Man.
Okay. By the way, what did the guy steal?
