Modern İnsan Popülasyonlarında Arkaik İzler

Adaptasyon evrimsel tarih içerisinde önemli bir süreçtir. Adaptasyonun en elzem ölçütlerinden birisi genetik çeşitliliktir. Canlıların genetik çeşitliliklerini düzenleyen birçok biyolojik mekanizma bulunur. Bu mekanizmalar insanın biyokültürel evriminde büyük bir paya sahiptir. Günümüz verileriyle anatomik olarak modern insanın kökeni Afrika'ya, 200 bin yıl öncesine dayanmaktadır. Homo sapiens tarih sahnesine çıktığında, yaşayan tek insan türü olmadığı bilinmektedir. Dünya üzerinde geçirdiği 200 bin yıl içerisinde modern insanın, Homo neanderthalis ve Denisovan gibi arkaik homininler ile gen alışverişinde bulunduğu ve karıştığı tespit edilmiştir. Bu gen akışı, göç ettiği bölgelere uyum sağlaması açısından önemli katkılar sunmuştur

Adaptation is an important process in the evolutionary history. The crucial parameter of adaptation is the genetic diversity. There are a number of biological mechanisms which adjust the diversity of the species. These mechanisms have a critical role in the biocultural evolution of human. According to the recent studies, anatomically modern human (AMH) originated from Africa 200 KYA. It is known that when it appeared, Homo sapiens was not the only human species on Earth. Throughout its history, AMH admixed and changed a sum of genes with other archaic hominins such as Homo neanderthalis and Denisovans. This gene flow helped AMH adapt itself to the new enviroment in the migrated areas.
