Answers to Evolution Questions - Research melodic theme ExamplePopulation growth rate in majority of populations is very high consequenceing in more(prenominal) offspring every year than that can be supported by the local resources. This leads to a trial for resources and in turn not all offspring survive. Differential reproduction - Those individuals with traits that atomic number 18 best accommodate to adapt to the local conditions are more likely to survive and reproduce. That is, more offspring will be contributed to the next generation by these individuals (James, 2010). The process of inborn survival of the fittest is one in which individuals with variations that are more favourable (to survive local conditions) than others are supported by the struggle for resources and as a result affect the populations trait frequency (Breed & Moore, 2012). The random and gradual process of natural endurance results in few traits being more common and some less common while some c an be completely absent in the future generations. A change in a traits genetic code is called mutation and this gives rise to variation. Mutations happen by chance and are in no way related to adapting to local conditions. Fitness is another concept that is at the essence of natural selection. Fitness is the ability of an organism to reproduce. If an organism can reproduce more than others in its species, therefore the genes of this species will be more common among the future generations. A recent example of natural selection is field table mustard. ... An experiment conducted showed that plants from seeds of 2004 had earlier flowering times than those of 1997. Therefore, in order to survive field mustard plants had to develop the trait to flower early and they did develop this (Judson, 2008). 2. The best example of human ontogenesis oer the past 10,000 years is the evolution of the human promontory. Research shows that human brain has evolved rapidly in the ultimately 10,00 0 years. The reason cited for this is that natural selection might have favoured different dispositions and abilities due to increased complexity of kind order and mechanics. As humans graduated from hunter-gatherer communities to farming communities, there were need for different skills and abilities such as mathematical ability and other intellectual abilities. Brain discipline corresponded to this through evolution (McAuliffe, 2009). Also it is argued that the development in the functioning of the hand has had an impact on brain evolution. As the functioning hand is fashion more complex from manufacturing of tools to use of more sophisticated device the brain has developed more move abilities accordingly. That is, our hands today are more capable of fine-grained motor skills and in response brain has developed abilities to motor these skills (Ruse, 2012). Even though there isnt much research done on this but there definitely will be effects of use of computer keyboards on the evolution of the brain. 3. A scientific theory is one which is a result of extensive research followed by experiments and observations conducted repeatedly that can be tested in the natural world. As a result of this, a scientific theory must be able to explain the observations through the development of mechanisms such as natural
