Even after adopting cattle, early east African herders kept hunting and gathering for 1,000 years

Eastern Africa's earliest livestock herders continued fishing, hunting and gathering for centuries after livestock were first brought to the region. The first pastoralists in eastern Africa didn't suddenly switch to a diet centered only on cows, sheep and goats. Instead, they kept eating a wide mix of foods—fish, wild animals and plants—alongside livestock for at least 1,000 years. The strategy may have helped them adapt to a harsh, changing climate.
