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 Bo 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. Human Hearing System (focus on the evolution of the mammalian hearing system) Human Vision System (stereoscopic, retinal fovea, trichromatic color vision) The Modern Human Tactile sense (touch)Explanation / Answer
Human hearing systems :
There have been numerous transitional forms of the auditory ossicles. The early mammal has a jaw joint, squamosal ans dentary. This dentary continued to enlarge at the time of Triassic and there was a no usage of quadrate articular joint, which later became free floating along with the angular. In most mammals, these occurred twice. During the mid Jurassic era there was only dentary and squamosal bones at the jaw joints. The Teinolopodos developed a mammalian middle ear which evolved independently in monotremes. It was discovered recently that Yanoconodon, a primitive mammal, developed ossicles that separated from the jaw and this serve do ghe hearing function in the middle ear. This was evident in hearing, as after the separation of the jaw joint, variations affecting hearing would develop unconstrained during the process of evolution. The mammalian ear evolved by the Jurassic era, in which the angular got converted into tympanic annula and the articular and quadrate became malleus and incus and got connected with the stapes in series.
Evolution of eye:
In the Cambrian explosion developed the complex ear appearance. This was observed in Middle Cambrian Burgess Shale. The adaptations of the eyes were observed as requirement for the organisms. These eyes varied in visual activity, in discrimination of colours, range of wavelengths that they can detect , low light sensitivity and resolution. Development of lens eyes from lenseless eyes appeared over time. In lens less eyes the light coming from a distance would hit the back of the eye with the same aperture as that of the size of the eye. The vertebrate lenses consisted of epithelial cells and developed by division of layers into transparent and non transparent layers by shedding of skin and filled with intracellular fluid depending on the depth of the layer. With time, there was development of transparent and non transparent layers which split and separated as cornea and iris. The forward layer further separated to form aqueous humour. The non transparent layer allowed ring formation that helped in more blood circulation of blood and larger size of the eyes.
Evolution of tactile touch :
The start was with the licking gesture. Licking their young ones would result in both physiological and psychological development. This helps the young ones from staying away from parasites. Humans have developed touch behaviour which has passed on from generation to generation seen in primates as a way of grooming their young ones.
