History of biology

It is easy to see how Darwin could have imagined that legs or arms would have been closely related to wings or fins; Behe attempts to render this line of thought obsolete, this explanation is too simplistic for the complex structures existing in biology. Again this is where Behe argues in favour of an intelligent designer, though this evidence does very little to support the theory as it only proves that the biological microstructures that make up life as incredibly complex. Darwin understood…

SPECIATION AND ADAPTATION Speciation is the evolution of biological species this is according to the Sage’s English dictionary and thesaurus. It is the continuous change in the genes of an existing specie until a formation of the new specie arise altogether. It is a result of two specie groups ceasing to share allele such that the genetic differences grow to the point of speciation. Many scientists have come up with different theories in an attempt to define and explain speciation, though…

primitively social behavior of Euglossa cordata (Hymenoptera, Apidae, Euglossini): a view from the perspective of kin selection theory and models of reproductive skew. The evolution of social behavior is perhaps one of the most controversial topics of biology, since the emergence of such behavior implies the evolution of altruistic traits that reduce the chance of reproduction (fitness) of individuals, through Natural Selection ( Freeman & Herron, 2009). Currently, there are models that link…

For decades, scientists have conducted research on all living things; to help us determine what life is, what life does, and why things live. During life, several miraculous things take place, and among those things is change. Change that can start a chain reaction over decades, centuries, even millenia. We call these changes evolution. There are, however, several doubts in the minds of people; most commonly, those people who believe in the words of the Bible. If evolution is a real thing, then…

RELATIONSHIP BETWEEN SPECIES DIVERSITY AND SIZE Effect of Surface Area on the number of species in biodiversity. Yes, there is a relationship between species diversity and size, the smaller the habitat the less diversity of species there will be. Species diversity is the variety of organisms that make up a community It has two components: • SPECIES RICHNESS: is the total number of different species in the area • RELATIVE ABANDANCE: is the proportion each species represents in that certain…

In the literature, different equations are used to calculate the energy requirement for birds (Emmans, 1974, Peguri and Coon, 1988, NRC, 1994, Sakomura et al., 1993, 2006), the factorial model has been the basis for the elaboration from these models, estimating the requirements consider the differences in weights, body composition, potential for growth and production of the animals, as well as the environment. The factorial method is based on the principle that the requirement in energy or…

As a Biochemistry and Molecular Biology major, English courses have always been viewed as inferior and subpar to STEM courses. Throughout the course, much of what was studied and the concepts that were introduced surprisingly fell in line with those of a scientist. Although science does involve quantitative analysis and calculations, it must all be translated into a dissertation explaining qualitative details. As the Winter quarter comes to a close, I have taken the time to reflect upon the…

reasons behind an animal spread are numerous. Several biological factors that influence the movement include the preference towards a resource, the presence of home range or the escape from preying. There is an extensive amount of work in mathematical biology about the effects of distinct behaviours on animal dispersal. How spatial memory influences the redistribution or the impact of the resource depletion in the population search for food and even the living circumstances for example. The…

CHARLES DARWIN. Darwin’s theory of evolution is widely looked upon, his theory has been around for a very long time and many people have looked into the theory. Charles Darwin was an english naturalist who studies of a variation of plants and animals during a five year voyage around the the world in the 19th century. Charles Darwin did explain his theory and his findings in his book called the “the origin of species”. This book was published in the 1859. Darwin's ideas caused a lot of…

Doctor in the making There I was going through the pig's trachea and went straight to his heart. Having a pig’s heart in my hands was amazing, nothing that exciting has happened to me until I decided to dissect a pig. I put the heart down and went on with my adventure, went to the pig’s stomach and poked a little hole in it, and brown liquid started to oozing out. It was probably the most disgusting but exciting thing I have seen in that class. When I found out my school offered physiology and…
