Investigadores suecos han encontrado nuevas pruebas de que el origen de la variedad de lobo ancestro de los perros domรฉsticos se localiza en el Southeast Asia. These results go against the theories that place the canine cradle in the Middle East.

El doctor Peter Savolainen, researcher in evolutionary genetics at the Royal Institute of Technology (KTH), concludes in a new study published this Wednesday that an Asian region south of the Yangtze River was the main place, and probably unique, where were wolves first domesticated by man.

Data on genetics, morphology and behavior clearly show that dogs are descended from wolves, but there has never been a scientific consensus on where in the world the domestication process began. ยซNuestro anรกlisis del cromosoma Y del ADN confirma que los lobos fueron domesticados por primera vez al sur del rรญo Yangtze, in southern China or Southeast Asia, lo que denominaos regiรณn ASYยป, says Savolainen.

STRONG EVIDENCE

Chromosome data and support the prior evidence of mitochondrial DNA. ยซEn conjunto, los dos estudios proporcionan una fuerte evidencia de que los perros se originaron en esta regiรณnยป, says Savolainen.

Los datos arqueolรณgicos y un estudio genรฉtico publicado recientemente en la revista Nature sugerรญan que los perros se originaron en Oriente Medio. But Savolainen rejects that view. ยซDebido a que ninguno de estos estudios incluye muestras de la regiรณn ASY, la evidencia de ASY ha sido pasada por altoยป, says.

Peter Savolainen and Mattias Oskarsson doctoral student worked with Chinese colleagues to discuss the male DNA of dogs around the world. Su estudio ha sido publicado en la revista cientรญfica Heredity.

Approximately half of the genetic reserve is shared universally around the world, mientras que sรณlo la regiรณn ASY tenรญa toda la gama de diversidad genรฉtica. ยซEsto demuestra que las reservas genรฉticas de todas las demรกs regiones del mundo probablemente se originan en la regiรณn ASYยป, says Savolainen.
