Document Summary
That process by which a population of animals becomes adapted to humans and to the captive environment by some combination of genetic changes occurring over generations and environmentally induced developmental events recurring during each generation. Huge difference between domestication and being tamed. For some animals, contact with humans can be stressful and prevent normal behavior . Changed environment from the original wild habitat. Came about via genetic changes amongst many generations. Reduction in fear and awareness of human predators. Humans able to hunt herbivores add meat into diet. Animals kept alive so meat wouldn"t spoiled. Kill rate increases and humans leave extra behind. Both parties are happy, esp because increased food. (some wolves tolerate humans health increases reproduction increases) Don"t kill me and i"ll bring you food . Increased association and connection between human and some species. Animals preadapted to human captivity successfully reproduced. How well it adapts with human interaction and contact.
