Question
impanzees and humans are very similar in many ways including skeletal muscle structure but chimpanzees are able to generate at least twice the force as humans of the same mass. An additional difference is that human have much greater fine motor control. Current hypotheses describing these differences are that chimpanzees have fewer motor units for a given number of muscle fibers and human central nervous systems put a limit on the number of motor units that may be stimulated at one time. Explain these physiological differences between humans and chimpanzees using the hypotheses mentioned above 3. Describe the details of the five phases cardiac cycleExplanation / Answer
Humans and Chimps are the two species' musculature is extremely similar, but somehow, pound-for-pound, chimps are between two and three times stronger than humans. "Even if we worked out for 12 hours a day like they do, we wouldn't be nearly as strong. Some of their muscle arrangement is different, the attachment points of their muscles are arranged for power rather than speed. It may be that that's all there is to it, but those who study chimp anatomy are shocked that they can get that much more power out of subtle changes in muscle attachment points. Their muscle fibers may be denser, or there may be physiochemical advantages in the way they contract.
Some studies suggested that chimps lack a "theory of mind": They cannot infer the mental state of another individual, whether they are happy, sad, angry, interested in some goal, in love, jealous or otherwise. Though chimps are very proficient at reading body language, Terrace explained, they cannot contemplate another being's state of mind when there is no body language.
The chimpanzee genome was sequenced for the first time in 2005. It was found to differ from the human genome with which it was compared, nucleotide-for-nucleotide, by about 1.23 percent. This amounts to about 40 million differences in our DNA, half of which likely resulted from mutations in the human ancestral line and half in the chimp line since the two species diverged.
