A newly discovered extinct human species may be the most primitive unearthed yet, with a brain about the size of an orange. But despite its small brain size, the early human performed ritual burials of its dead, researchers say.
This newfound species from South Africa, named
Homo naledi, possessed an unusual mix of features, such as feet adapted for a life on the ground but hands suited for a life in the trees, that may force scientists to rewrite their models about
the dawn of humanity.
Although modern humans are the only human lineage alive today, other human species once walked the Earth. These extinct lineages were members of the genus
Homo just as modern humans are. The earliest human specimens found yet are about
2.8 million years old. [

Though the researchers aren't sure how far back this human relative dates, it is the newest addition to the genus
Homo. "It's a very exciting finding," said paleoanthropologist Ian Tattersall at the American Museum of Natural History, who did not participate in this research.
However, Tattersall suggested these new hominins might not belong to genus
Homo. "I'm a great advocate for the notion that the genus
Homo has been made overinclusive," he said. "I don't like to stuff new things in old pigeonholes. I don't think we have the vocabulary needed to describe the diversity we're seeing in early hominins."
