Homo antecessor

Homo antecessor is an extinct human species dating from 1.2 million to 770,000 years ago. It is is one of the earliest known human varieties in Europe. 
The best-preserved fossil is a maxilla (upper jaw bone). It belonged to a 10-year-old individual found in Atapuerca, Spain. There were numerous examples of cuts on bones. The flesh had been cut from the bones. Maybe "H. antecessor" could have been cannibals.
"H. antecessor" may have been broad-chested and rather heavy, much like Neanderthals. Its limbs were proportionally long, which is a trait more frequent in tropical populations. The kneecaps are thin and have poorly developed tendon attachments. The feet indicate "H. antecessor" walked differently from modern humans.
"H. antecessor" usually made simple pebble and flake stone tools out of quartz and chert, but they also used other materials. This industry has some similarities with the more complex Acheulean. Acheulean is found in African and later European sites. Groups may have sent hunting parties to kill deer in their savannah and mixed woodland environment. As mentioned above, many of the "H. antecessor" specimens were cannibalised, perhaps as a cultural practice. There is no evidence they were using fire, and they only lived in Iberia during warm periods, presumably retreating to the South coast otherwise.
