What has been found between dogs and humans is something less frequently demonstrated: psychological convergence. Dogs have independently evolved to be cognitively more similar to humans than we are to our closest genetic relatives. [90] Dogs have evolved specialized skills for reading human social and communicative behaviour.
Many animals on this second table are at least somewhat altered from wild-type animals due to their extensive interactions with humans, albeit not to the point that they are regarded as distinct forms (therefore, no separate wild ancestors are noted) or would be unable to survive if reintroduced to the wild.

[6] The term remained loosely defined until the 21st century, when the American archaeologist Melinda A. Zeder defined it as a long-term relationship in which humans take over control and care of another organism to gain a predictable supply of a ...
Beginning of animal evolution. [54] [55] 720–630 Ma Possible global glaciation [56] [57] which increased the atmospheric oxygen and decreased carbon dioxide, and was either caused by land plant evolution [58] or resulted in it. [59] Opinion is divided on whether it increased or decreased biodiversity or the rate of evolution. [60] [61] [62 ...
Those animals established a commensal relationship with humans in which the animals benefited but the humans received no harm but little benefit. Those animals that were most capable of taking advantage of the resources associated with human camps would have been the tamer, less aggressive individuals with shorter fight or flight distances.
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 ...
Today's herding dogs have evolved a unique set of traits and mannerisms that makes them ideal for the job. [36] Herding dogs may generally fall into several categories, these are protectors, drivers, headers, and heelers. [37] Herding dogs rely on many predator skills such as posture and eye contact rather than brute force. [38]
