Extinction Punctuated Equilibrium Evolutionists for generations after Darwin imagined a slow and steady process of adaptation, in which daily culling and breeding success very gradually adapted a population from one form into another. Such a proces Continue Reading...
By using animals in research, and through animal research science learns how certain chemicals "interact with living systems"; this knowledge can be "translated into protection of humans, animals, and the environment from toxic levels of natural -- Continue Reading...
The well-being of an animal, preservation of species and biological diversity is always given first priority when it comes to deciding upon the appropriateness of research to be undertaken (Lin, 2013). It reaches a point in time when some animals h Continue Reading...
The subject of the book is clearly applicable to the field of paleoanthropology because the same techniques can be applied to studies of human populations and their response to changes in the environment. In the contemporary world, the discussions Continue Reading...
Animals in captivity, for example, have often been genetically, behaviorally or anatomically manipulated in order to enhance acclimation to the new environment. Similarly, animals have been neutered, declawed or defanged to be more compatible with t Continue Reading...
Animal Rights Introduction to the ESA According to Merriam-Webster's Dictionary of Law (1996) the Endangered Species Act (ESA) obligated the government to protect all animal and plant life threatened with extinction. Included in this category are e Continue Reading...

The extinction of birds will have a devastating effect on other species, largely through the destruction of plants upon which they feed. The loss of scavengers could harm human populations by reducing the chance of disease spread. The loss of scaven Continue Reading...
These abilities are inclusive of memory emotion, belief, desire, intentional actions and an awareness of the future. With these things being understood this theory asserts that mammals not only have physical bodies that are alive but they also funct Continue Reading...
Early Education Shows No Benefit (HSLDA 2007) This article argues for the viewpoint that Head-Start-type early education is not only non-productive, but can actually lead to detriments to children's development as they enter formal school. The art Continue Reading...
Animal research is a necessity today, and has afforded us the opportunity to create lifesaving drugs and vaccines, new surgical procedures and improved diagnosis of disease. Despite the bad press animal activists have given, institutions are given gu Continue Reading...
The fur industry is well-known to house minks and other animals raised for their coats in cruel conditions and to kill them by such devices as anal electrical probes designed to kill without damaging fur (HSUS 2007). The problem is that the underly Continue Reading...
However, there simply does not seem to be sufficient evidence for the disease hypothesis. First, there has been no evidence of disease found. Next, even extremely virulent diseases, like the plague or West Nile Virus, do not have the kill rates nece Continue Reading...
Without the mass extinction of the dinosaurs, is doubtful that human beings would ever have evolved in the first place. By comparison to the effects of the that meteorite, all of the human activity in the world that has ever occurred since the first Continue Reading...
Front-line Application The most obvious front-line application of this study is in the conceptualization of the relative needs of the respective species in connection with human efforts to prevent extinction, especially extinction that is directly Continue Reading...
Marine Life Extinction Caused by Over Fishing Our planet consists of 75% life-giving, life-sustaining water. From lakes to oceans, man relies on the waters of this planet to provide nourishment for survival - from drinking water to food to eat. Over Continue Reading...
animals -- whether they are carnivorous, omnivorous, or herbivorous -- depend upon the mechanisms of photosynthesis as a source of food. Carnivorous and omnivorous animals eat other animals as a source of food, but prey animals such as herbivores co Continue Reading...
Extinction Theory and Its Impact in Contemporary Society The apparently sudden mass extinction of Dinosaurs marks the boundary between the Cretaceous and Tertiary periods. This catastrophic event has also triggered a large amount of interest in both Continue Reading...

Contrary to what one would expect if the extinction were gradual, the existing history of fossil records indicates that dinosaur were doing quite well up and that there were no factors threatening their extinction but that suddenly there is a comple Continue Reading...
With the purpose of finding out what the minimum population to be introduced in a nature reserve was, wildlife biologists employed a computer simulated (stage 2) reproductive history of each bear in a population and altered the number of individuals Continue Reading...
In fact, when looking at the records of the environmental fights and debates that have been fought in the past, it is no surprise to see the aspect of animal suffering and extinction being given its due attention. It is also interesting to note that Continue Reading...
A survey of scientific responses to extinction at the present moment is fairly unambiguous, however. Paleontologist James Kirchner calculated in 2002 that extinction rates could more or less be statistically inferred from the fossil record, and use Continue Reading...
Biodiversity The natural environment is the source of all our resources for life. Environmental processes provide a wealth of services to the living world -- providing us with air to breathe, water to drink and food to eat, as well as materials to u Continue Reading...
Wild species, which includes that of animals, plants, and of other organisms, constitute the most part of the seafood of the world and of the timber. The Wild species provide a means of earning to the communities apart from providing them with food, Continue Reading...
