	Description:		Archeologists know early humans used stone to make tools long before the time of Homo sapiens. But a new discovery out this week in Nature suggests early humans in eastern Africa were also using animal bones – one million years earlier than researchers previously thought. The finding suggests that these early humans were intentionally shaping animal materials – like elephant and hippopotamus bones – to make tools and that it could indicate advancements in early human cognition.
