New York Times u članku Fossils in Kenya Challenge Linear Evolution objavljeno 9. kolovoza 2007. piše: "Scientists who dated and analyzed the specimens — a 1.44 million-year-old Homo habilis and a 1.55 million-year-old Homo erectus — said their findings challenged the conventional view that these species evolved one after the other. Instead, they apparently lived side by side in eastern Africa for almost half a million years."
