Bipedalism

As Mary and Louis Leaky had finally found fossil evidence of some of the earliest ancestors of Humans in this area, East Africa's Great Rift Valley is important because it is a place where the earliest of Hominins could be found. It help to expand scientists understanding of where early humans used to live, which changed our understanding of their "variability and geographical distribution". It now opens more theories in what environmental conditions the early humans might have lived in and how that played out in their survival and evolution. Almost all hominin fossils can be found here and contribute to the research of the "last three quarters of the century".

When looking at the development of bipedalism within humans and like-hominins,

While primitive ancestors used to use their hands for walking, bipedal organisms use their feet for walking instead, which allows for the hands to be better used for tool making and other motor skills. Another major benefit to bipedalism and possibly one of the most significant is the ability to walk and run great distances and speed. The Valgus knee provides the stability to do so and the Longitudinal foot arch serves as a "shock absorber". The increased length of the legs allows for greater stride and the S-shape of the spine allows for that additional support for both walking and running. Bipedal movement has many theories of how it arose and how it came to the benefit of evolving humans; however, there are some cons that have arisen due to our changed anatomy. Since we stand, we need support to hold our top weight up, causing our spines to take an S-shape rather than the C-shape of

Since their development, they have allowed scientists to reconstruct fossils and fragments in their findings into clearer pictures which has contributed to the amount of detail we know about the organisms. Those who wish to know the cranial structure of a fossil now have a greater view of the shape of the skull, seeing every crevase and every piece that has been worn away over time. Not only do they benefit from that, but the majority of anthropologists are now able to look at their work in further detail with a lot less damage to the fossil because it doesn't have to be as man-handled to find out the same information. 3D laser scanning allows for the least amount of damage to the object at hand, which is key to decreasing tainting or harm to that subject. Looking through the internet, I saw that 3D printing has a large presence in the field of anthropology; however, there are other developing areas of science that are using, or planning on using, this technology as well. Those in the medical field could use it to get a better image of the anatomy of their patient. While x-rays are only two dimensional, image how much more biological information could be told from a 3D image. They would have a lot better understanding of bones and muscles, allowing for faster and more accurate treatment. Another interesting topic that I stumbled upon is the use of 3D scanning in the food industry. It is speculated that if
