Do­mes­ti­cated, twice!

Down to Earth - - SCIENCE -

RE­SEARCH SUG­GESTS that man's best friend may have emerged in­de­pen­dently from two sep­a­rate (pos­si­bly now ex­tinct) wolf pop­u­la­tions that lived on op­po­site sides of the Eurasian con­ti­nent. This means that dogs may have been do­mes­ti­cated not once, as widely be­lieved, but twice. The team re­con­structed the evo­lu­tion­ary his­tory of dogs. They also an­a­lysed the mi­to­chon­drial DNA from 59 an­cient dogs liv­ing be­tween 14,000 to 3,000 years ago and com­pared them with the ge­netic sig­na­tures of more than 2,500 pre­vi­ously stud­ied mod­ern dogs.
