Thank you so much.
Refer to class lecture notes, study guides, the Evolution, Making Sense of Life text, (especially chapters 16, 17 and 18), Dan Leiberman's The Story of Human Body, the Your Inner Fish text and video series (video available online at HHMD, as well as legitimate internet sources like Wikipedia (watch out for Creationist sites). 1. Trace the evolutionary history and adaptive significance of each of the following human adaptive complexes or deep adaptations. adaptative complexes that we modern humans have inherited from out deep evolutionary past. In other words, develop an illustrated/illuminated handwritten account that traces the evolutionary history of each complex across deep time. The Human Hand (with long, strong opposable thumb, short fingers, nails backing tactile pads with dermato precision and power grip, etc.) The Human Locomotor Adaption (bipedial locomotion, relatively long legs adapted to long distance walking and running) Human Skin (sparse surface hairs, pigmentation, vascularization, subcutaneous fat, etc) The Human Spark" (modern humans with archaeological evidence of full cultural capacity, symbolic consciousness, language, music, a mythic imagination, etc.)Explanation / Answer
Evolutionary history for Human hands
According to literature the high levels of hand disparity among modern hominoids are deriveon the baisi of different evolutionary processes: autapomorphic evolution in hylobatids it reveals about extreme digital and thumb elongation, however, digital elongation discuss the convergent adaptation between chimpanzees and orangutans and comparatively little change in gorillas and hominins. later it was discovered that the human high thumb-to-digits ratio required little change since the LCA, and was acquired all together with other highly dexterous anthropoids.
Evolution about Human locomotors adaptation
Terrestrial locomotion which discribe that organism moves by means of its two rear limbs or legs was discovered in hominids more than 4 million years ago. Such form of locomotion was among the population refered as Bipedals were a diverse group including the lineage of obligatory walkers that finally lead to humans. Important anatomical changes observe in this group were: enhanced lumbar lordosis, ilium become shorter, and emphasize on the parasagittal movements. Long-distance running was associated with well-developed plantar arches that was evolved much later. The strengthening of muscles supporting the erect trunk, and seprate the pectoral girdle and head. In addition to anatomical changes, humans have many physiological adaptations to long-distance running. It is likely that the ability to run long-distance has been important for the survival of species.
Human skin
Skin is the most important bridge between human bodies and the environment. It carry the impact of dealing with many environmental stresses like excesive heat and sivere cold, the environmental chemical and insect bites etc. The correlation between coloration and climate was getting firmly beleive with the discovery. It was postulated that organisms those live under tropical sunlight have dark skin, or they have dark exposed areas and because of which they have high melanin formation in the skin. Humans simply became huge melanin factories as it directly come into exposure of sun light under the influence of natural selection when they lost most of their body hair which is a very important step in the evolution of humans. The ancestors of Western Europeans and Eastern Asians that led to loss of pigmentations as people dispersed into those areas. We can suerly beleive because both of these groups today have lightly pigmented skin, although they are not from the same set of genetic changes.
Human spark
The Human Spark is from archaeologists finding which is evidence through the fossilized bones and tools of our ancestors which is followed by primatologists that discover our nearest living relatives to explore what we have in common and what sets us apart. In the caves and rock shelters of the Dordogne region of France archeologists once thought to be the first record of people whoes minds resemble like our own. The people who painted the caves, our ancestors, were attractively different, possessed of what we are calling the Human Spark. We are separated from our nearest relatives, the chimpanzees, by only one or two percent of our genes by some 6 million years with different evolutionary ways. The eyes of a chimp remind us strangely. But we are also aware that behind those eyes is a mind that was totally different from our own. Later Alan gets a highly detailed scan of his brain and resemble a man in his early 70s, is in remarkably good shape. It is the starting point for a evolution within his brain as well as the brains of others.
