The fossils, discovered in the dark places of the Rising Star cave in South Africa, belong to a new species that appeared at the beginning of the family that includes modern humans.The fossils could be more than 2.5 million years old.Or they could be relatively recent. Homo sapiens (智人) appeared in Africa roughly 200,000 years ago, so the bones are at least that old. The new species is a strange mixture of parts.It had hands and feet much like those of other members of the biological group called Homo, which includes our own species — Homo sapiens.Its brain, though, was only about as big as an orange. The Rising Star ancient humans could control objects with their hands, but their highly curved (弯曲的) fingers also made them good climbers.Their Homo like feet and long legs show they could walk long distances, but their shoulders are also suited for climbing.The researchers call them Homo naledi, after the word for “star” in the African language Sotho. The first slight knowledge of the more than 1,550 bits of fossil, representing at least 15 individuals, came from cavers helping a researcher to look for ancient remains.One place leading to the fossil room is just over seven inches wide — less than the width of a sheet of notebook paper.It took a team including six female scientists, chosen for their small size and research experience, to get the fossils. The scientists believe that the bodies were deliberately placed in the cave.It suggests that ancient long ago human relatives became involved in ritual (仪式的) disposals of their dead. 1．What do we know about the Rising Star ancient humans A．They were very good at climbing.

Probably the most important thing kids learn is how to have peer relationships. As a parent, you can't do this, because you and your child aren't equals. For example, when you're sitting on your fa ... ...
