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,

It is this paper’s position that the human race came about as they are now through the process of evolution. The author believes that living organisms today evolved through the process of natural selection and this has been the key to the survival of living things on earth.
This then reaches the motor plate, which is a collection of muscle fibers. Acetylcholine, a neurotransmitter, causes the resting potential to change resulting in the sarcoplasmic reticulum to release calcium II ions. Then, these ions cause the movement of troponin and tropomyosin that causes movement in the filaments.
The cellphone technology is already 38 years old. It started in 1973 when Dr. Martin Cooper, Motorola’s researcher and executive, made a first call on the first cellphone that was made. The call was made to Dr. Joel S. Engel of Bell labs and was patented under his name on October 17, 1973 under the name “Radio Telephone System”.
Archaeological studies have revealed that humans have existed in various forms in the past. Skeletons of giant humans up to ten times the size of an average modern man have been found. One of the most interesting forms of humans whose traces have been found are Neanderthals.
Walking upright is one of the important characteristics or traits of humans which distinguishes it from other species. This paper will discuss and explore as to how humans learned to walk upright on two legs and what physiological changes have actually allowed humans to actually walk on their two legs.
This write-up briefly describes the origin, insertion, intended actions and preferred exercises of some major surface muscles located in our body such as Triceps Brachii; Biceps Brachii; Deltoid; Brachioradialis; Brachialis; Pectoralis major; Latissimus Dorsi; Trapezius; Rectus Abdominis; External Oblique; Gluteus Maximus; Rectus Femoris etc.
The nerves prompt body’s effectors (muscles that release a specific set of substance depending on the stimulus), to action.
The skeletal system supports movements and provides protection for its delicate internal organs. It cannot move without the help of
Adaptations are produced by natural selection and are well-fitted to their function. Many forms can be taken by adaptation, for example, an anatomical feature that allows the organism to access a new and valuable resource, a protein that
phenomenon in a wide array of fields, with proponents passionately defending it with scientific bases, despite the very lack of scientific visibility for such evolution alluded to in the definition above. To be sure, the argument extends to the very irrefutably evidence that no
