Answer: Kenya
Notes: In July 2025, scientists extracted 18–20 million-year-old proteins from the tooth enamel of extinct mammals found near Lake Turkana. Lake Turkana is located in northern Kenya and partly extends into Ethiopia. It lies in the Eastern Rift Valley and is mainly fed by the Omo River, which supplies 90% of its water. It is the fourth-largest lake in Africa and the world’s largest permanent desert lake. Lake Turkana is a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site.
