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 first animal to be domesticated by humans was the dog, as a commensal, at least 15,000 years ago. Other animals, including goats, sheep, and cows, were domesticated around 11,000 years ago. Among birds, the chicken was first domesticated in East Asia, seemingly for cockfighting, some 7,000 years ago. The horse came under domestication ...
The cattle dog has long worked alongside humans, with the start of herding activities roughly being around the time of the domestication of the sheep. [35] Today's herding dogs have evolved a unique set of traits and mannerisms that makes them ideal for the job. [36]
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 ...
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.
