After this week’s studying, there are many categories for us to identify the unknown hominid. Here I want to mention is the morphology. By the morphology, we can identify the hominid species by comparing the size of their brain. With the findings of paleoanthropologists, the brain sizes, or can be described as encephalization, is an increasing of size and complexity of a brain. Based on the size and complexity, it means a species will more evolved if it has a comparatively larger and more complex brain. Like different animals have different size and complex. And the lines inside the brain also increase the complexity of the brain. Moreover, the size and shape of the teeth is also a useful evidence within morphology. By the evidence of paleoanthropologist, they can classify different species by checking dental patterns. Since different animals have different dental patterns, paleoanthropologist can easily classify the specific species. Also, the dating method is a good way for identifying. Paleoanthropologist can use dating method to figure out the range of the age of a bone, and then determining the hominid by its bone’s age and other evidence. Besides the dating method, comparing the size of bone can also be helpful to classify a unknown kind of hominid. By comparing the bone with some exist bone of hominids, it will be much easier to classify which species is more similar. And more, classify the hominid species by walking technique is also useful. Since once the species is bipedal, it seems like show more evidence to prove it is a hominid. By all of these classify method in morphology, it will give more and more specific ways to determine the hominid.
Homo naledi is one of the new found hominid species. It was found in south Africa two years ago.The evidence is its brain size and their bone size. The way Paleoanthropologist use to identify is similar to the lecture material. They compared its bone to existence bone of hominid, and use the ruler to measure its bone’s size. For this case, I think the morphology is interesting. The ways for determining unknown hominid comparasion with different kinds is really useful.
