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.
