their lives in extensive burrow systems (Nowak, 1991; O¨ zkurt et al., 2005) and are obligate hibernators during seasons with low ambient temperatures and poor foraging conditions (Armitage 1981). The genus Spermophilus of ground squirrel with 41 species (Helgen et al, 2009) is Holarctic in distribution, occurring throughout temperate and arctic Eurasia from Austria to eastern Siberia, China and Mongolia and ranging across western North…

Mount Everest has some of the greatest surviving animals on the planet. Now lets get busy and discover some of…

There are too many species in the world to even try to count, and overtime all of them have had to adapt and evolve to survive in their habitats. Some species have changed in color over time to be able to blend better with their environment for survival. While other species have grown fins, some have grown legs, some have even changed to be both water and land, and others wings. One of the many animals that has evolved and grown wings is the bat, although bat wings are different because they…

further our species medical technology. By researching this topic, we’ve stumbled on a creation called “chimeras” which are animals that carry human DNA, resulting in the growth of usable human organs. The article, “The Mammoth Cometh,” by Nathaniel Rich, discusses the use of these chimeric experiments to bring extinct animals back from the…

In Aristotle’s view, everything in this world can be categorized. Living beings include plants and animal. The plant has nutritive soul and the animal process both nutritive soul and perceptive soul.

planet and that it is the reason why Earth is not going to be able to sustain us for much longer. Many people believe, however, that the population of the human race isn’t the reason for Earth’s decline in resources. It is, in fact, us. We, as a species, are solely responsible for Earth’s sudden decline in sustainability. It is not how many of us there are, it is how we live and how we produce, consume and waste our many resources. One of the biggest issues in todays world has a lot to do with…

Paramecia, unicellular cilliated protozoa, usually are ovoid and elongated. They widespread in brackish environments and freshwater. Length of the species are various ranging from 50 micrometers to 330 micrometers. They feed on yeasts, algae, and small protozoa which are captured by them through phagocytosis, devouring a particle by “wrapping pseudopodia around it and packaging it within a food vacuole” (Campbell and Reece 2011). They also serve as the models for the study of basic biological…

In 1859 Charles Darwin published his book “The Origin of Species”. This book explained his theories of how animals and humans were formed. The beginning of the earth has been a mystery frustrating the minds of scientist for many years. Darwin’s Theory of Evolution is a change in the genetic material of a population of organisms from one generation to the next. Though changes produced in one generation are normally small, differences with each generation overtime can become substantial changes in…
