Download file to see previous pages As there is more selection of a particular trait that is inherited by the species, there is more regression. In the case of no heritability, there is no regression as new variations are produced. In reality, what usually happens is something that is a middle path. This can be seen in the experiment that is seen in Evotutor. Here, when the parameter of selction is placed at five, that of regression is 3.25. however, when the parameter of selection is reduced to 3.0, that of regression reduces to 1.95. This enables a better understanding of the ways in which selection works.
Variation is another aspect that is changed through the ages and leads to evolution. When there is greater variation in a society, there is greater change in the following generations of the species. When there is very less variation, the reverse happens. However, another important aspect of this is the way in which the variations are distributed. If a large part of the variations happens in the case of a particular trait, then evolution and selection would proceed in that direction, leading to the development of subspecies and then different species altogether. This can be seen in the histogram that Evotutor provides. When the level of variance in a society is placed at 125, the division between different colors reads different numbers where the variations within the population are divided into different permutations and combinations. This is seen in the constant change that the graphic shows while analyzing the data. However, when the level of variance is increased to 720, the variations within the populations are much more diffuse. No single variation has a hegemony and this can be seen in the constantly changing leader in the ...Download file to see next pagesRead More
