Fossil of beaked whale was discovered in desert of west Turkana in East Africa . The marine mammal 's remains were unearthed 459 miles from the ocean . It is thought to have swam up the ancient Anza river after taking wrong turn . At the time Kenya would have been flatter , wet and covered in forest . Scientists say this marks a key point before the landscape began to rise . This caused the climate to dry and the habitat to become less forested . Researchers say led the primates living there to evolve bipedal walking .
