Extract of sample "The Evolutionary Development of Adaptive Radiations"

How does the environment cause the evolutionary development of adaptive radiations? The entire dynamics of the evolutionary process is based on environmental factors. Evolutionary concepts such as Darwinism and Lamarckism have recognized the role of environmental factors in the evolutionary development of a particular species. Perhaps the best example of this is the famous Darwin’s finches that belonged to the same ancestry but owing to the different seed types present in the different islands, they radially adapted for survival, thus giving rise to several species mildly different from the original ancestral ones.
Often owing to several environmental factors mostly disharmonic ones, speciation occurs, where a certain population of a species adapts to their new environment, develops a whole new niche and ultimately becomes a different species. The Galapagos Islands and the Hawaiian Islands are among places where adaptive radiations and convergence are noticed because these islands are relatively new than most Mainland and have radically different ecology and environmental niches. Wilson in his book the Diversity of Life, says that the 10,000 species of insects that now inhabit the Hawaiian islands have originated from a mere 400 species owing to adaptive radiation (Wilson, pp95). In his book we find one of the best examples of adaptive radiation in the Hawaii’s. The Islands itself has different biodiversity and environment and genus Caconemobius have adapted themselves to different ecological niches in the same island. Some have left land existence and have become partial marine and live in boulders, another population of the same genus is blind and live in dark caves and yet another population of the same genus lives on lava flows (Wilson, pp96). This shows that the different population of the genus adapted to the new environment and developed a whole new niche for themselves and gave rise to a new species.
Cocos juvenile finches have the tendency to imitate feeding habits of warblers and sandpiper birds hence this is an embryonic state of radiation. If circumstances allow radiation Cocos finches will also meet adaptive evolution in the coming times.
Another more livid example of adaptive evolution is the Lake Victoria cichlids. A study of these cichlids reveals the changes in each species and reveals the steps in adaptive evolution owing of changes in their environment (Wilson, pp109).
An important part of biodiversity is the interactions between the abiotic and biotic elements in form of niches. Each species has its own niche. Often species from different adaptive radiation converge and occupy the same ecological niche. This is where interspecific competition surfaces. The Tasmanian wolf of Australia and true wolf both occupy similar niches. Wilson in his book states that there is a limit to which two fully radiated species can coexist (pp 128). However over maturity of adaptive radiation species leads to imperfect convergent radiation like that seen in the Hawaiian woodpeckers (pp 100).
Adaptive radiation never ends; as long as environmental changes are met and species can successfully adapt, radiation from original species will occur.

...? Evolutionary Psychology Tyfanny Payne Pennsylvania Schuylkill This paper was prepared for the Evolutionary Psychology, taught by Dr. Scherer. Abstract 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. Evolutionary Psychology 1. Look at women's long-term mating preferences. According to evolutionary psychology theory, which preferences make sense...

...of behavior in the entire population. For example, if majority of the population is generally gullible and trusting, a behavioral morph; cheater or sociopath, may be advantageous in a way. Nevertheless, from the perspective of evolutionary psychology, like several other psychological adaptations, personality traits may be considered facultative: sensitive to the typical variations within the social environ, particularly during very early development. For instance, children who are born later in a family are most likely to be rebellious than the ones born earlier, more open to new experiences and less conscientious, this may be specifically advantageous to them because of their specific...

Swedish scientist have in the recent past pointed out that there is a huge possibility of humans developing Alzheimer disease due to exposure to phone radiation. They also put in two other diseases, Parkinson's and multiple sclerosis. Recently scientist's from the Radiation and Nuclear Safety found out that the prolonged use of human head to the cell phone radiations damages the blood circulation safety in the brain. This leads to the destruction of the barriers which protect the blood toxins from going into the brain and...

Adaptive leader

...An Adaptive Leader A leader in the military must be able to adapt to any situation. When they cannot they may be a detriment to the people they serve. According to Whiffen a leader who is adaptable is one who is able to adapt to the situation they are in no matter what the situation (1). They are able to modify what they need to do. In the military this is very important because a leader can be put in many different situations that will require him to adapt very quickly to the environment. Wong (qtd. in Whiffen 2) states that an adaptive leader must live with a certain level of unpredictability. They are able to be flexible and open to...

...”(Blevins 25). Additionally, in considering the biological element, Blevins proposes that a central foundation is the direct genetic inheritance and shared genetic traits on the basis that there is a parallel evolution and physical constraints in the form of function along with non-natural factors. In reinforcing this point, Blevins opines that “the first and most usual explanation is that similar characters reflect direct genetic inheritance” (Blevins, 47). However, Blevins’ evolutionary phonology goes beyond acceptance of pre-existing scientific concepts and the neogrammarian approach by highlighting the point that the development and learning of a language is rooted in adapting to...

Evolutionary Theory

...Evolutionary Theory Species have been traditionally defined biologically as organisms that can freely interbreed giving rise to a viable offspring. However, as more studies are being carried out, more information about species is being discovered which has led to development of new concepts about species and their evolution can be conceptualized under the new available evidence. The discovery of new species of organisms is usually placed within the taxon genus. Currently, 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 a neighboring Island...

...-existing opportunity may not be responsible for the adaptive radiation (Wilson, 1992). Theoretical explanations are available to highlight the fact about the rare existence of replicated adaptive radiations, they are found to occur only in inadequately distributed taxa prevalent in some specific areas of the world. Possibility of a diversity of numerous species may generally exclude resemblance in evolutionary diversification. The fact remains unclear that radiations generally disclose processes necessitating phylogenetic rebuilding of ancestral episodes. The amalgamation of environmental provisions encompassing genetic, biological,...

The evolutionary development of maize

...The Evolutionary Development of Maize Many researchers including Zeder claim that maize might have originated from a large wild plant referred to as teosinte which was classified under the genus Euchleana1. In relation to his claim, it is apparent that maize was probably domesticated from the plant teosinte. The diversity of maize is linked to infection of genes that resulted from Tripsacum, a related genus to Euchleana. Despite this claim, research carried on maize and teosinte showed that there was a significant variation between the two plants. According to Zeder, the variation might have been as a result of little chromosomal variation between the two plants2. In support of this assertion, the...
