DNA degrades over time, so it’s difficult to be confident in any given A, C, T, or G in an ancient genome. In a study published on October 30 in Science, a group of geneticists, evolutionary biologists, and archaeologists makes use of another source of data: ancient dog DNA. Domesticated dogs, wolves, and dingos all belong to the same species, even though dogs diverged evolutionarily from wolves sometime between 15,000 and 40,000 years ago.

But, for some reason, the opposite happened when it comes to the wolf genome: Dogs are universally more related to some wolves than they are to others, which indicates that dogs did in fact contribute genetic material to wolf populations. Ultimately, however, they concluded dogs can, in fact, recognize facial features. It uses in the process widely knowne Mechanisms and was developed, to at 90 tireden Accompaniments as well as cheap .
