The list of typical human-specific phenotypes should never be considered as a welter. In contrast‚ it is really important to identify their appearance time and how they interacted with each other as an adaptive strategy in human evolution. Bipedalism is the first human-specific phenotype in the evolution of hominin species. According to the analysis of some footprint fossils left by Australopithecus‚ this species had already learned to walked without their forelegs. This event occurred about 3.6

stimuli. - Retinitis Pigmentosa is the degeneration of rods and cones. These are the cells which capture and process light helping us to see: the cones with clear central vision and color vision. RP mutates the function of the rod and cone cells and they slowly stop working. This first leads to night-blindness and as the disease progresses and more rod cells degenerate‚ loss of peripheral vision or tunnel vision occur. Other forms of retinal degeneration first affect cone cells and central vision

"Parkinson’s disease is a chronic degeneration of the Central Nervous System that produces movement disorders and changes the cognition and mood." (Vene‚ 1529). Progressiveness of this disease becomes noticeable around the mid50’s to late 60’s and it’s most prominent in males. The degeneration is due to the deficiency of a neurotransmitter‚ a chemical that controls nerve cells‚ called dopamine. Dopamine’s main

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

This reduces the pressure of natural selection in human society‚ which‚ in turn‚ worsens the physical and mental constitution of offspring‚ leading to degeneration. According to Rafter‚ “Galton invented the term eugenics to denote efforts to breed better human beings and prevent reproduction by the unfit” (Rafter‚ 2011 p.237).

sex determining genes are involved which include male-sterility and female-sterility factors. There should not be any recombination between different loci which is the pivotal reason for the genetic degeneration of Y chromosomes. There are several theories attached to Y chromosome degeneration that are reviewed recently . Introduction: why are plant sex chromosomes of particular interest? Sex inheritance and sex chromosomes in plants are similar to those in animals. In many sexually reproducing
