Biology

Question 1 : Theoretic models of the biological growing and the comrade 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 ontogenesis as such and have lead , and continue to do so , to the emergence of the variety of species as we know them . Of civilise , homo sapiens is perhaps the most interesting species from the evolutionary point of view . In this regard , it is interesting to tense up to predict what key innovation , which is a modification in structure or function that permits a species to exploit the milieu in a more efficient or uninfected way compared to the ancestral species , have homos developed or to date may to develop . It must be pointed let on from the outset that modern military mans are virtually friction match genetically to their early ancestors of approximately 100 thousand get along 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 relate our ability for the adaptive light beam in fresh environments . But what has the most immediate relation to the adaptive shaft of humans is our engine room , which for the last millennia has been the key innovation author profound changes in our life style and the penetration in new environments .

Thus , in ! the distant future technology may enable humans to live in antecedently hostile environments either by means of adaptation to them , or maybe even by transforming them into comfortable onesQuestion 2 : Since the mid-sixties , the traditional approach to the estimation by means of fossils cross-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 explanation as both an auxiliary and the primary mode . The reason why this widely discussed tool is considered reliable is that forthcoming usher suggests a correlation of rates of evolution among standardized evolutionary lineages , which in its turn can be explained by the equal factors of influenceSourcesThe Associated Press (2005 Study Suggests Human Brains Still Evolving .
