domestication

And the researchers' digital scans of the skulls that they studied will allow them to answer more questions about the evolutionary driving forces behind domestication.

Rendered impotent by domestication, she’ll do anything to influence human events.

Another excavation by the researchers in June 2023 -- of an 8,100-year-old canine jawbone at a nearby site called Hollembaek Hill, south of Delta Junction -- also shows signs of possible domestication.

But the new research shows that the shrinking genetic diversity associated with domestication happened much faster in horses.

"Up to now relatively little has been known, however, about how the root system developed over this period of domestication and afterwards."
