Domestication Of The Cat
The domestic cat originated from Near-Eastern and Egyptian populations of the African wildcat, ''Felis silvestris lybica''. The family Felidae, to which all living feline species belong, is theorized to have arisen about 12 to 13 million years ago and is divided into eight major phylogenetic lineages. The ''Felis'' lineage in particular is the lineage to which the domestic cat belongs. Several investigations have shown that all domestic varieties of cats come from a single species of the ''Felis'' lineage, ''Felis catus''. Variations of this lineage are found across the world, and until recently scientists have found it difficult to identify exactly which region gave rise to modern domestic cat breeds. Scientists believed that it was not just one incident that led to the domesticated cat but multiple independent incidents at different places that led to these breeds. More complications arose from the fact that wildcat populations as a whole are very widespread and very similar to o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domesticated Indoor Cat WI
Domestication is a multi-generational mutualistic relationship in which an animal species, such as humans or leafcutter ants, takes over control and care of another species, such as sheep or fungi, to obtain from them a steady supply of resources, such as meat, milk, or labor. The process is gradual and geographically diffuse, based on trial and error. Domestication affected genes for behavior in animals, making them less aggressive. In plants, domestication affected genes for morphology, such as increasing seed size and stopping the shattering of cereal seedheads. Such changes both make domesticated organisms easier to handle and reduce their ability to survive in the wild. 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
