Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome led by researchers at Washington University School of Medicine in St. Louis reveals some surprising clues.

The research appears Nov. 10 in the Proceedings of the National Academy of Sciences Early Edition.

Cats have a relatively recent history of domestication compared with dogs; canines arose from wolves over 30,000 years ago.

"Cats, unlike dogs, are really only semidomesticated," said senior author Wes Warren, PhD, associate professor of genetics at The Genome Institute at Washington University​. "They only recently split off from wild cats, and some even still breed with their wild relatives. So we were surprised to find DNA evidence of their domestication." [...] sciencedaily.com

Actualización 18-11-14: Identifican las mutaciones que marcaron la evolución del gato doméstico
Un estudio del genoma del gato doméstico, que posee alrededor de unos 20.000 genes, ha permitido observar las diferencias especie -en términos biológicos, evolutivos y de comportamiento- entre esta especie y otras como el gato montés, el tigre, el perro, la vaca y el humano. Los gatos, como los perros, se domesticaron hace unos 10.000 años, coincidiendo con el neolítico y la agricultura...
