[90] Dogs have evolved specialized skills for reading human social and communicative behaviour.

The lineages of modern dogs and wolves may have split thousands of years earlier than previously thought. According to new research, the divergence happened around 27,000 to 40,000 years ago, far ...
These gene variations were unlikely to have been the result of natural evolution, and indicate selection on both morphology and behavior during dog domestication. These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response [ 26 ] [ 81 ] (i.e. selection for ...
Caninae (whose members are known as canines (/ k eɪ n aɪ n z /) [6]: 182 is the only living subfamily within Canidae, alongside the extinct Borophaginae and Hesperocyoninae. [7] [1] They first appeared in North America, during the Oligocene around 35 million years ago, subsequently spreading to Asia and elsewhere in the Old World at the end of the Miocene, [6]: 122 some 7 million to 8 ...

Some were buried with artifacts, e.g., stone blades, birch bark and antler ...
