As the Great Ice Age came to an end, some 11,000 years ago, North America was thought to be home to as many as 50 species and subspecies of horse. But studies of ancient DNA tell a rather different story, suggesting the horses belonged to just two species... The caballines are thought to be the ancestors of today's domestic horse... The Oxford research suggests that the stilt-legged horse, which was thought to have migrated into North America from Asia, at a time when the continents were linked by a land bridge, appears, in fact, to be native to North America.Fascinating that the horse appears to be native to North America. I believe the same used to be said of the wolf and all domesticated dogs. I doubt that these findings will catch on. I would like to think that they would lead to the demise of mtDNA GIGO.
Mitochondria, the powerpacks of the cell, have their own DNA and are inherited along the maternal line. Their DNA mutates at a stable rate...Heh... Please ping me, if you see articles appropriate for GGG ping.

OK, what gives here? How is it that fossilized bones can contain any DNA. Isn't everything replaced during the fossilization process. I've really got to get out from under this rock more.
