A number of factors determine how quickly any changes may occur in a species, but there is not always a desire to improve a species from its wild form. Domestication is a gradual process, so there is no precise moment in the history of a given species when it can be considered to have become fully domesticated.
The first domesticate was the domestic dog (Canis lupus familiaris) from a wolf ancestor (Canis lupus) at least 15,000 years ago. The Younger Dryas that occurred 12,900 years ago was a period of intense cold and aridity that put pressure on humans to intensify their foraging strategies.
De novo domestication refers to the process by which wild species are intentionally transformed into domesticated varieties. [1] The majority of domesticated species has been under domestication for millenia, with the first animal, the dog, having been under domestication for between 40,000-30,000 years, and the first plants since the start of the Neolithic Revolution, approximately 12,000 ...
A Czechoslovakian Wolfdog. The domestic dog (Canis familiaris) is a domesticated species of the gray wolf (Canis lupus), along with the dingo (Canis lupus dingo).Therefore, crosses between these species are biologically unremarkable and not a hybridization in the same sense as an interbreeding between different species of Canidae.
Conversely, not all domesticated animals are working animals. For example, while cats may catch mice, it is an instinctive behavior, not one that can be trained by human intervention. Other domesticated animals, such as sheep or rabbits, may have agricultural uses for meat, hides and wool, but are not suitable for work
Although closely related to domesticated dogs, wolves do not show the same tractability as dogs in living alongside humans, and generally, a greater amount of effort is required in order to obtain the same amount of reliability. Wolves also need much more space than dogs, about 25 to 40 square kilometres (10 to 15 sq mi) so they can exercise. [1]
Domestication syndrome refers to two sets of phenotypic traits that are common to either domesticated plants [1] [2] or domesticated animals. [3] Domesticated animals tend to be smaller and less aggressive than their wild counterparts; they may also have floppy ears, variations to coat color, a smaller brain, and a shorter muzzle.
