Polynesian Migration To Americas Evidenced On Chicken Bones

There are several theories that explain the spread of humans across the Pacific to Polynesia, among others expressed by Kayser. Between the years 3000 to 1000 BC, the expansion of Taiwan through the Philippines, Indonesia and East-West, of New Guinea to the islands of Melanesia, occurred around 1400 BC. It is estimated that the spread of human reach western Polynesia around 900 BC.
Genetic evidence found in the original Polynesian chickens reveal early movement and trade patterns in the Pacific. According to Dr. Vicki Thomson, scientists were able to trace the origin of the lineage that originated from the Philippines and provide clues to the source population of Polynesian chickens.
Actually, a lot of theories that reveal ancient human colonies in the Pacific, these obvious they make contact with the South American mainland. As seen in domestic animals, in this case is chicken, in the early exploration has left a record of genetic and can be traced to solve the mystery of Polynesian migration to the Americas. Project team of scientists under Professor Alan Cooper has been reviewing the chicken bones used in previous studies, linked to the migration of ancient Pacific and South American chicken.

In the analysis of Polynesian migrations initial contact has been found to be contaminated with some of the results of modern chicken DNA, and there is no evidence to explain the existence of the domestic chicken DNA contacts pre-Colombus.

Original Polynesian chicken lineage until now survive in some isolated Pacific island, despite the introduction of the European domestic chicken ever spread in the Pacific during the last few hundred years. Native Polynesian lineage is very worrying, especially for the poultry industry may be reduced genetic diversity and could be of commercial value in the future.
