What did evolution do to our muscles - Essay Example However, humans do not come close to comparing to chimps’ strength and the percentage points that humans and chimps differ are extreme due significant anatomical and physiological differences. The way in which muscles are attached to bones is different in chimps compared to human, which enables chimps to have enhanced mechanical advantage in both arms and strength. The paper explores why chimps enjoy powerful strength relative to humans. Evolution changes manifest on the genetic levels passed from one generation to another. The changes manifest at the genetic level overtime as the organisms’ genes mutate and/or recombine within diverse ways during reproduction and are passed to future generations. Scientific evidence demonstrates that the physical and behavioral traits shared by humans emanated from apelike ancestors and evolved overtime. Bipedalism remains one of the most prominent human traits highlighting how humans have evolved. Other traits include development of a large and complex brain, capacity for language, and capability to make and utilize tools. Muscle contractions form the basis of movement within a majority of the species (Muehlenbein 137). Chimps are stronger that humans centers on the fact that they do not have closely as many fine control over their muscles. Humans enjoy the capability to d precise things such as operating complex machinery, which necessitates choice of minute sizes of muscle fibers. Hence, humans sacrifice strength over precise control of their muscles. The nervous system exercises significant control over the muscles relative to the chimp muscles. Studies have revealed that chimps have relatively reduced grey matter within their spinal cord compared to humans. Spinal grey matter features a significant amount of nerve cells that link to muscle fibers and control muscle movement. This details the process that allows finer control of the muscles. As a result,
