![]() ![]() Their discovery set off years of debate in the scientific community, with some rejecting the idea that they were from a previously undiscovered species with close links to the homo genus and others floating the idea that they were from two different species altogether.īut the new research has laid those suggestions to rest, and outlined “numerous features” the skeletons share with fossils from the homo genus. “Australopithecus” means “southern ape,” a genus of hominins which lived some 2 million years ago. Two partial australopith skeletons – a male and a female - were found in 2008 at a collapsed cave in Malapa, in South Africa’s “Cradle of Humankind.” AFP PHOTO / ALEXANDER JOE (Photo credit should read ALEXANDER JOE/AFP/Getty Images) ALEXANDER JOE/AFP/AFP/Getty Images Baptized Australopithecus sediba, the partially fossilized specimens - an adult female and a juvenile male - were found in 2008 in a cavern 40 kilometers (24 miles) from Johannesburg. Two skeletons of a new hominid species dating back two million years and found in South Africa have shed light on a previously unknown stage in human evolution, scientists said today. We have relatively larger eyes and flatter faces.The remains of an hominid, may be one of the most significant palaeoanthropological discoveries in recent times, are unveiled on Apduring a press conference in Maropeng. Human, apes, and monkeys rely more on sight than smell. Because of this, they have longer snouts, which give them more pointed faces. Lemurs and lorises rely pretty heavily on smell. Primate sensesĪs for sight and smell, the ability of these sensory organs (eyes and nose) differs depending on the primate. Most primates don’t use canines as weapons but yawning is seen as a threat gesture. They are sharp and pointy and are excellent natural weapons. In primates, canines have evolved a second purpose. Other primates have differently shaped teeth, likely because they eat different types of food. Human molars and premolars are rounded with nooks and crannies good for grinding down food while our incisors are wide and thin, perfect for cutting into food. Without them, how could you chew a steak or bite into an apple? Primates are mammals, so we have the same four different kinds of teeth mammals do: molars, premolars, canines, and incisors. Human teethĬhewing is the main job of teeth. Many scientists agree that relatively larger brains indicate greater brainpower. ![]() ![]() Our brains are bigger than you would expect given our body sizes, which means that our brains are relatively larger. Does this big elephant brain mean they are smarter than humans? No, elephants are not more intelligent than us. For example, would you expect an elephant’s brain to be larger than ours? Yes, elephants are much larger animals so they should also have a larger brain. When we talk about brain size, it is important to consider brain size relative to body size. Scientists think this spherical shape fits the most amount of brain tissue into the smallest amount of space. Our skull is also more globular (round like a sphere) than in other primates. Humans have larger brains than other primates. So what about these body parts makes us human? The human brain All of these important parts of your body are in your skull. Your brain thinks, your mouth chews your food, your ears hear, and your eyes see. Your head is the most important part of your body. ![]()
