History of biology

According to Easthope, the concept of hybridity could be generally understood from three aspects—“biology, ethnicity and culture” (Easthope 341). Its etymology, “hybrida” that derives from biology, means a “genetic component”—two species could produce the offspring inherited some characters from, but not being any one of, both species. Its ethnical meaning refers to “an individual ‘having access to two or more ethnic identities’,” which, in Easthope’s sense, has its own limitations, for it…

Indeed, Thayer's (1896, 1909) and Cott's (1940) works are still hugely influential and contain a range of untested ideas. However, in spite of its long history and widespread occurrence, research on natural camouflage has not progressed as rapidly as many other areas of adaptive coloration, especially in the last 60–70 years. There are several reasons for this, including that human perceptions have often…

everyone’s favourite web-slinging superhero. All three have something in common, and it's more common than you might think. Every one of these things have been manipulated by humans at the lowest level we can, while still calling the science we used biology and not chemistry. We are of course referring to genetics, or more accurately, Genetic Modification and Engineering. To the uninformed and naive, any kind of control of genes may seem like the actions of the villain in a superhero story. In…

ANIMAL TESTING In today’s society, many people have debated over the idea of vivisection otherwise known as animal testing. This controversial topic questions whether people should make animals submit for the greater good of humanity or to not be utilized as animal test subjects. It’s has been in debate since the seventieth century. The majority of states in the past several years have passed laws regarding animal testing; saying it should be more humanized. Many people would think animal…

natural selection process, which arises through preference by one sex for specific characteristics in the member or members of the other sex. The purpose of this paper is to complete and present the requirements of the assignment on the Evolution Biology. The paper covers the issues that pertain to sexual selection such as the theoretical background as well as the evidence for models of mate choice. Furthermore, the writer covers the aspects of game theory and animal conflict as well as sexual…

Your Inner Fish by Neil Shubin Chapter Questions Chapter 1 – Finding Your Inner Fish 1. Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils. Be sure to include the types of rocks and their location during their paleontology work in 2004. The author and his colleagues chose to focus on 375 Million Years as it was a period when the transformation took place from fish to fish with limb. The fish without characteristics of…

Recent technological advances in biology have prompted me to want to study the subject as an undergraduate. I have been drawn to how the world works and what everything is made up of since secondary school, but in recent months my focus has shifted specifically towards the study of genetics. A wide and varied subject, ranging from eugenics and the ethical considerations of genetically engineering organisms, and to the more recent scientific breakthroughs in said area of study, the study of…

Animal Experimentation Cosmetics and medication providers both test on animals; with this being said most animals skin is nothing like humans, there are genetic differences between animals and humans. With a lot of cosmetics and soaps there will be a label that will either say “This product has been tested on animals” or “This product has not been animal tested”. More and more products are beginning to be tested on animals. There are pictures of products on the internet and other places that…

In order to survive under several environmental influences, animals must possess biological mechanisms which enable them to regulate and maintain their internal environment. Temperature is one of abiotic factors that are inexorably linked to every animal’s physiological functions since it is considered a strong source of selective pressure on animals (Miller, 2010). Animals are categorized into thermoregulators and thermoconformers based on their mechanisms to maintain their internal environment…
