History of biology

When the name “Case Western Reserve University” is mentioned, a myriad of subjects come to mind: research, science, engineering, breakthroughs, and technology, to name a few. In our great university, there seems to be a wider appreciation among students for the sciences than for the humanities -- this does not come as a surprise considering that CWRU is primarily a research university, and faculty and students have been conducting magnificent and ground-breaking scientific research for decades.…

Darwin 's theory of evolution is a widely held concept that all life is related through the descent of a common ancestor with modification. It presumes the development of life from non-life and how complex creatures evolve over time from more simplistic ancestors by a process called natural selection. According to Darwin’s observations and inferences, natural selection arises from heritable variations (i.e size, shape, behavior, color) among population members, high fertility rate, differences…

Importance of Microbes Introduction It was long ago when Man realized that, along with animals and plants, he was also accompanied by some other organisms as well, and though which remained hidden from his eyes. Those organisms were unveiled by Anton Van Leeuwenhoek, who first saw the tiny organisms which accompanied Man through the lenses of microscope. Later it was found out that microorganisms inhabited each and every surface of earth, on man himself, or even inside him, resided under the…

Scientific experiments and observations have led to many discoveries, which in turn have allowed scientists to develop a better understanding on the way diseases originate in humans. Molecular biology in particular has allowed scientists to discover the way in which domains, found in proteins impact a genome. Domains are autonomous folding units that carry out specific functions and mechanisms in a certain protein. These functions consist of being responsible for interactions in the cell, which…

sin Mohamed Mohamed1 Biology 9B Mr. Ryan May 21 2016 Evolution A common misconception about the theory of evolution nowadays is that it promotes human society to act in selfish ways because of “survival of the fittest”. 
 People who believe in this statement will start asking why is this a misconception. The reason…

selection, based on the idea of female choice drives the evolution of particular traits, is accepted my most theorists. Currently, sexual selection is one of the fastest-growing and most exciting areas of evolutionary biology and animal behavior. It is important to understand the peculiar history of sexual selection theory because virtually all of 20th century psychology, anthropology, paleontology, and the social sciences and humanities, developed without recognizing that sexual selection could…

With natural selection its major driving mechanism, evolution is the change over time in the makeup of genetics of a population. Supported by evidence from many scientific methods, Charles Darwin, in On the Origin of Species, asserts that inheritable variations occur in individuals in a population. In the process known as natural selection, due to competition for limited resources, individuals with more favorable characteristics or phenotypes are more likely to survive and better reproduce,…

Animal Testing Necessary? Over the years animal testing has been used to advance medical research and expand human knowledge in medicine. Animals are used for genetic, biology, drug and cosmetic testing experimentations, some people feel that animal testing is necessary in finding better medicine and beneficial for humans. A lot of people don’t understand that many of these animals may suffer during the harsh experimentations. People question whether or not it is ethical to use animals for…

Education In the CSI episode “Burked,” one of the featured analysts was a forensic entomologist. Forensic entomologists apply their knowledge of insects to a variety of investigative purposes, such as estimating the time since a person has died (Investigating Forensics). Forensic entomologists can also apply their knowledge to establish a connection between the victim and a suspect, or to determine the geographic location of the victim’s death. Other responsibilities of forensic entomologists…

Throughout the history of biology and psychology there has been a firm belief of the effects of nature versus nurture. This belief explains that humans have innate traits when they are born but new ones can be developed throughout time. In the book Empire Falls there are many characters that display this change of character but more importantly the books shows how it affects their own and others lives, one such character is Tick Roby. Tick was first introduced to us as a burdened teen, but…
