Kotieläinlaji

Kotieläinlaji refers to a species of animal that has been domesticated by humans and is kept for specific purposes such as food, labor, or companionship. This domestication process involves selective breeding over many generations, leading to genetic and behavioral changes that distinguish domestic animals from their wild ancestors. Key characteristics of domesticated species include a reduced fear of humans, increased tameness, and a greater dependence on human care.

The earliest known kotieläinlajit include dogs, which were domesticated from wolves thousands of years ago, likely for hunting assistance and companionship. Other early examples are sheep and goats, primarily raised for milk, meat, and wool. Cattle, pigs, and chickens followed, becoming crucial for agricultural societies providing sustenance and other resources. Horses and donkeys were domesticated for transportation and labor.

Modern domestic species are diverse and serve a wide range of functions. While many continue to be vital for food production, others are primarily kept as pets, contributing to human well-being and emotional support. The development of different breeds within a single species is a testament to human intervention and selective breeding for specific traits, such as coat color, size, or temperament. The relationship between humans and kotieläinlajit is a cornerstone of human civilization, impacting agriculture, economy, and culture.
