The Kri-kri, a feral goat, preserves traits of the early domesticates. Presence of animal domesticates also may be affected by fragmentation and preservation of faunal remains. The longest established invertebrate domesticates are the honey bee and the silkworm. Animal domesticates include chicken, guinea fowl, dog, sheep/goat, and cattle. The trail of plant domesticates indicates an initial foray from the Levant by sea. Cattle were the first domesticates in North Africa around 10,000-8000 BP. Domesticates consisted of pigs, dogs, and chickens. The domesticates spread into farther Oceania, as well.
