In May, another research team found upper and lower jaws that included teeth, which are believed to have belonged to a new species of hominin, the subset of hominids that includes modern humans and our direct ancestors. The fossils are thought to date back 3 million to 4 million years ago, meaning ancestors to modern humans may have been more diverse than initially understood.
A younger skull — just 430,000 years old — was recently found at an archeological site in northern Spain. The site is located deep underground in a cave and holds the skeletal remains of at least 28 early humans. Scientists discovered lethal wounds on the fossilized skull, proving that deadly interpersonal violence is an “ancient human behavior,” the scientists said in a study, published in the journal PLOS One.
