Scientists believed the first humans were from East Africa. This changed because they found 2.4-million-year-old stone tools in Algeria. Scientists now say the first humans were from Algeria. They found 250 tools and 296 animal bones. The bones show that early humans cut up meat.
Archaeologists have been digging on this project for 25 years. The site is 200 miles from Algeria's capital. The project leader said humans killed animals for meat 600,000 years earlier than we thought. The tools showed that early humans were more than scavengers. Scientists now want to find even older stone tools.
