Biology

Question 1 : Theoretic models of the biological growing and the buster discussions devoted to this fundamental concept of the modern science be often centered on the investigation of the specific biological and genetic mechanisms of natural selection and of other factors that have enabled growing as such and have lead , and continue to do so , to the emergence of the variety of species as we know them . Of running , homo sapiens is perhaps the most interesting species from the evolutionary point of view . In this regard , it is interesting to stress to predict what key innovation , which is a modification in structure or function that permits a species to exploit the environment in a more efficient or new-fangled way compared to the ancestral species , have homos developed or nonetheless may to develop . It must be poin ted let on from the outset that modern mans are virtually stir genetically to their early ancestors of approximately 100 thousand age ago . Those insignificant changes that have been occurring since the dawn of homo sapiens , such as the possible continuation of the growth of the human brain`s size (The Associated Press , 2006 , do non dissemble our ability for the adaptive light beam in young environments . But what has the most immediate relation to the adaptive actinotherapy of humans is our technology , which for the last millennia has been the key innovation commove profound changes in our life style and the penetration in new environments .

Thus , in the distant ! future technology may enable humans to live in previously hostile environments either by means of adaptation to them , or maybe even by transforming them into comfortable onesQuestion 2 : Since the sixties , the traditional approach to the estimation by means of fossils data file analysis of the time when organisms developed and evolutionary diverged was augmented by molecular(a) genetic studies that uncovered workings of the so-called molecular clocks , which are very helpful for the investigation of the evolutionary register as both an auxiliary and the primary mode . The lawsuit why this widely discussed tool is considered reliable is that forthcoming try out suggests a correlation of rates of evolution among standardized evolutionary lineages , which in its turn can be explained by the like factors of influenceSourcesThe Associated Press (2005 Study Suggests Human Brains Still Evolving .
