  The first inhabitants of present-day Kenya were hunter-gatherer groups, akin to the modern Khoisan speakers. These people were later largely replaced by agropastoralist Cushitic (ancestral to Kenya's Cushitic speakers) from the Horn of Africa. During the early Holocene, the regional climate shifted from dry to wetter conditions, providing an opportunity for the development of cultural traditions such as agriculture and herding, in a more favourable environment.
  
  Around 500 BC, Nilotic -speaking pastoralists (ancestral to Kenya's Nilotic speakers) started migrating from present-day southern Sudan into Kenya. Nilotic groups in Kenya include the Kalenjin, Samburu, Luo, Turkana, and Maasai.
  
  By the first millennium AD, Bantu -speaking farmers had moved into the region, initially along the coast. The Bantus originated in West Africa along the Benue River in what is now eastern Nigeria and western Cameroon. The Bantu migration brought new developments in agriculture and ironworking to the region. Bantu groups in Kenya include the Kikuyu, Luhya, Kamba, Kisii, Meru, Kuria, Aembu, Ambeere, Wadawida -Watuweta, Wapokomo, and Mijikenda, among others.
  
  Notable prehistoric sites in the interior of Kenya include the (possibly archaeoastronomical) site Namoratunga on the west side of Lake Turkana and the walled settlement of Thimlich Ohinga in Migori County.
