There are several traits that can show us about human biology, such as teeth. Hominins all have teeth which provide us with extremely valuable information, such as what a species eats or whether or not they fought with other animals. It can tell us if the hominin was a meat eater or strictly ate non meat. You can instantly relate this alone to the topic of fossilized remains being important to look at the past and see human ancestors. Without fossilized remains, we could not study what kind of animals were alive in the past and what they did and how they relate to humans. It is immensely important as it gives us species that could be our potential ancestors and allows us to study the earlier form of bipedal species that could be extremely similar to us. Without fossils anthropologists would be a lot less informed and a lot more lost about this subject and hence we wouldn’t even know that teeth played an important role in illustrating human biology as well. The first ancestors we had seemed to have canine teeth, which as i mentioned before can be used to attack predators or hold onto branches. These canine teeth eventually turned into molars for chewing over time, which could be an example of how they are in human evolution as well. We have canines and molars for chewing and cutting as they teach you in anatomy. We can also look at the brain and head size of our hominins. The brain and skill capacity is just another distinction which separates several hominins. Certain traits came along with bigger heads and larger brains such as using tools. Could this mean that a larger brain allows us to have intelligence and a trait of using tools. The size of the skull is also linked to bipedalism. As hominins had larger brains they eventually became bipedal. They adapted more and could start using tools, the study of these things are all linked when it comes to the increase of the brain use. As you can see it is a rather important trait as well. You can also look at limb length and see whether or not hominins were climbing like creatures of did they stay in open fields. This is yet another trait that can be studied in order to figure out whether or not they are related to us in any way. Basically looking at all these traits illustrates a few things all in all. The study of all these characteristics can allow researchers to place hominins in certain time eras and illustrate how they evolved slowly but surely over time. It can also make them reconstruct the past with the same type of knowledge. If they can look at characteristics of hominins they can look back at the ancestors of certain people and determine whether or not they were actually from the same family. All in all, the fossilized remains and characteristics that are observed are vital to the study of evolving and adaptation as well as the study of our past.
