Postcolonial Indices: Brachia Index Monterey Peninsula College Keywords: Hummer, skeletal Indices, locomotion, arboreal, fabrication, Biped, Quadruped, Percolator Abstract I measured multiple Hummer and radiuses from multiple mammals Including H. S. Sapiens In order to correlate a hypothesis on how they move using their Individual brachia indexes. Generally speaking fabrication is associated with the major alterations in the arm, thorax and hand. The more powerful the arm movements, more robust and "stronger" the stabilizing musculature must be.
Materials and Methods The materials I used included a lightweight field esoteric board, and a pair of spreading calipers. I measured the length of the radius from the Proximal Epiphysis to the Distal Epiphysis and recorded the length in millimeters. I then did the same for the hummers. I then found the fabrication Index by using the equation (R) Radius length / (H) Hummers length X 100 or R/H(OHIO). I did this for the Sea Otter (Anhydride ultra), Human (H. S.
It Is one of the many Indexes we use to see how the animal moves. For example we can assume that all of the mammals on the list above besides the human and otter, are in some form swinging from trees because of the higher index. We can take the assumptions to another level. If the arms are longer then the legs then we can assume the animal will be a knuckle walking and fist walking. If the legs are longer than the arm then we can assume bipedal. If the legs are longer then the arms then we can assume leaping and arboreal.

Discussion I found that there are several types of fabricators. The gibbons and the signings primarily use arm swinging as a way of getting around and are said to be the best kinds of fabricators. Although the fabricator Indexes Imply that humans and chimpanzees are not the best on the charts they are certainly capable, but they do to practice this as their primary source of locomotion. We as humans are the only ones dedicated to only using bipedal does not mean that the other primates are to upright almost human like. Non-human primates use bipedal locomotion when carrying food.
One hypothesis for human bipedal is that it evolved as a result of successful survival from carrying food to share with group members. The Chimpanzees forearm is relatively long in comparison to the humans. The major differences between chimpanzees and humans limbs are contrasts in relative proportion. Some anthropologists believe that fabrication could be a premeditation o bipedal. It was astonishing to me that humans brachia index is so similar to an otters but the otter was in no way designed to swing from a tree.
It is also baffling to understand that a ring-tailed lemur, highest on the brachia scale, is closer on this index to an otter then too human. But we have the ability to climb and swing if we so desire. So it poses the question as to why the brachia index of the otter says it could swing from trees but the otter has yet to evolve this desire to do so. So what we can conclude from the brachia index is that the environment plays a significant role in evolving the ways in which animals move. Reference Elaine N. Evident, W. C.
