Bio 101- Introduction to Biological Sciences I. Brief History of Biology. List down the contribution(s) of the following philisophers/scientists to the science of Biology Pre-historic people: The earliest humans must have had and passed on knowledge about plants and animals to increase their chances of survival. This may have included knowledge of human and animal anatomy and aspects of animal behavior (such as migration patterns). However‚ the first major turning point in biological knowledge

Change is constant in life. Yet‚ all my life I’ve met people who constantly resist change with all they have. So here I’m going to write from my personal believe and experience what I should be saying and already said in some cases‚ to these people about the inevitable- change. Why do we do not like changes? When bigger changes are happening around us‚ we often kick and scream‚ or rant and rave‚ or cry and whine. Is it because we feel that we are not in control of our lives and our realities?

How did each of the following sources view the origin of species? Aristotle and Scala Naturae: Aristotle viewed species as fixed. Through his observations of nature‚ Aristotle recognized

Group selection describes natural selection operating between groups of organisms‚ rather than between individuals. This would produce adaptations that benefit the group‚ rather than the individual. Darwin’s theory of evolution was based upon individual selection‚ and he rejected the idea of group selection. Artificial selection is the selective breeding carried out by humans to alter a population. It is a procedure often used in agriculture: artificial selection has been used to alter the number

own species. When Darwin published On the Origin of Species in 1859‚ he was aware that applying the concept of natural selection to humans would create controversy in a religious Europe‚ and therefore only briefly mentioned that‚ “[i]n the distant future I see open fields for far more important researches […] light will be thrown on the origin of man and his history” (Darwin‚ 1859). He waited another 12 years to revisit the issue of human evolution in The Descent of Man (Darwin‚ 1871)‚ in which he

Creationism should be taught in schools alongside of evolution. There are many different views on creationism and its scientific truth but also there many different views of evolution. A poll was released that stated that two thirds of all Americans say that creationism should be taught alongside evolution. President Bush once said that‚ “both evolution and the theory of intelligent design should be taught in schools so people can understand what the debate is about.” Many people say that creationism

Once explained I will put forward my argument against these with the support of arguments from the likes of Hume‚ Darwin and Dawkins. When considering the arguments in support of the theory for design a line can be drawn between those before and those after Darwin’s theory of evolution (Chappell‚ 2011‚ p. 73). This discovery heavily impacted on those arguments from

The film Gattaca is an American film that premiered in 1997‚ about a future society where babies are conceived through genetic manipulation to ensure that they possess “favorable” traits. The film is about Vincent Freeman‚ who was born outside of genetic manipulation and faces genetic discrimination because of it. Gattaca takes place in the not so distant future where eugenics‚ the practice of “improving” genetic quality is common. In this society‚ there is a database that classifies those as “valid”

The sticky slime helps to hold clusters of soil particles together in formations called aggregates. Charles Darwin spent 39 years studying earthworms more than 100 years ago. Worms are cold-blooded animals. Earthworms have the ability to replace or replicate lost segments. This ability varies greatly depending on the species of worm you have‚ the amount

However‚ natural selection cannot account for characteristics that seem disadvantageous‚ for example‚ the peacock’s tail and the stag’s large antlers‚ both of which would inhibit escape from predators. Darwin solved these problems in 1871 when he proposed the theory of sexual selection e.g. large antlers increase the chances of survival and reproductive success‚ as they are better at fighting for the harem.
