From the discussion in the paper "Evolutionary Theory," it is clear that these two species evolved from one single species over time and space. Their ancestor was the same, they evolved differently due to environmental conditions that were different on the two islands…

Numerous species have not been named and as such lumping of organisms together as belonging to the genus and species classes may be incorrect as the case in the repopulation program in the Islands of St. Kitts and the neighboring Island of Nevis. These two species of rodents appear to be identical in morphological features and that is the reason why they were taken to be of the same species. However, their morphological similarities have nothing to do their genetic makeups since the DNA (Deoxy-Ribonucleic acid) are quite distinct from each other. The differences in DNA can be explained through concepts of evolutionary theories of natural selection of stabilizing selection and diversifying selection
This is a type of natural selection that experiences genetic diversity decrease in a population that that is stabilizing. It has been argued that this is the most common way through which natural selection takes place. As such, the stabilization process employs negative selection which results in organisms with intermediate phenotypes being selected. In the case of the two islands, it is quite clear that the rodents from the St. Kitts Island underwent a stabilizing selection because their traits seem to be normal or not very much different from those of the rodents from the other island of Nevis. Probably, the two islands were connected and after a natural disaster like an earthquake, they became separated. It follows that those rodents that had intermediate phenotypes were selected over those that had extreme phenotypes hence the development of the new distinct species.
Diversifying selection is used to refer to the exact opposite of stabilizing selection whereby the extreme phenotypes in organisms are naturally selected over the intermediate phenotypes. This can be explained by the studies done by Charles Darwin in the Galapagos Island with regards to the finch populations.

The article aims to understand if evolutionary psychology has potential to become a metatheory for psychology. In an effort to know this, the authors have compared the views and perspectives of evolutionary psychology and evolutionary developmental biology to see if evolutionary psychology is complete and broad enough to include all the perspectives of some of the major issues in psychology.
However, this theory is contradictory to the evolutionary theory of Darwin. One of the most controversial question is that how can the process that takes place in the practical sense in all living organisms, increases vulnerability to death, decreases reproductive capacity and other undesirable changes that are not favorable for the well being of individuals.
On one side the table there are 6 chairs, and on the other side 5. On the side with 6 chairs, the guests seated are, in the order running from my end of the table to that with the empty chair: Gregor Mendel, Thomas Malthus, my Mom Leigh, Wilhelm Weinberg, and Aristotle.
Evolutionary psychology seeks to determine the traits of human psychology that evolve adaptations. That is the functional products of sexual selection or natural selection of human beings. Some evolutionary psychologists have applied a similar thinking to psychology and argued that body and mind have similar modular structure with different modular adaptations that serve different functions.
The Darwinism theory has, however, given a special direction to the evolutionary theory of ethics in connecting good conduct with survival. What en evolutionary theory might legitimately say about survival between different types of conduct which survives in a 'struggle for existence' between different types of conduct is the better - a view to which it would have the support of the popular press which seems to hold that the type of civilization of the conquerors in a war is always better than of the vanquished.
The theory of psychology is faced by a number of challenges. The greatest challenge is the need to take in huge amounts of data. Because of the mind’s complexity, theorists who study it must develop a complex strategy for dealing with findings (Marr and Poggio, 1977; Marr, 1982).
Leading academic Blevins’ work in “Evolutionary Phonology” (2007) focuses on recurrence of sound patterns in world languages in an attempt to formulate an explanation for the similarities in sound patterns.
Blevins’ theory of evolutionary phonology
ars, but prominent biologists and geologists could not accept, evolution has an enormous potential of special creation, where species have separate origins and do not change or change only within narrow limits. Two factors stymied evolutionary thinking, first the doctrine of
Evolutionary Psychology is a branch in psychology that examines and identifies several traits that are involved in evolution, such as sexual selection. This branch of psychology also proposes that the present human behavior is a product of adaptation because of survival. This paper deals with all these as it tries to answer several questions.
