Decent Essays
There are notable differences between domesticated and wild animals. They are more obvious when compared between different breeds of the same species. For most domesticated species, the variations within an organism are usually descended from a single wild species. Variation arises from natural selection, and refers to variation both within and between species. Darwin did not believe that all domesticated species arises from a common wild ancestor, however, modern genetics disproves this.
Research shows that all domesticated dogs arise from their wild ancestor, the wolves. Similar trends are found in other domesticated animals like cats, horses, cows, and birds. Specifically, I will be analyzing the trends in domestication of fowl and poultry. Fowl includes two orders of birds: landfowl (chicken, quail, pheasant) and waterfowl (duck, goose, swan). Fowl typically refers to wild birds. Poultry indicates birds that are domesticated and raised for meat or eggs. By analyzing the behavior, evolution species variation, and domestication of birds, we can determine the traits selected for different species. Through domestication, many breeds of birds have evolved with alterations that could be seen as adaptations to the environment.
Behavior of Wild Fowl It is widely known that the domestication of an organism involves numerous changes: genetically, physically, socially, mentally. An interesting occurrence to note is reduction in brain size from wild to domestic animals. As
