Vu Nguyen BIOL 1003/22 ANTIBIOTIC RESISTANCE LAB REPORT Introduction Natural selection is a non-random process in which individual with favorable traits for the environment will likely survive and reproduce than those without these traits. In contrast to Natural selection‚ Artificial selection is the process in which desired traits are intentionally chose to breed among individuals. Antibacterial resistance is the process in which strong and highly resistant bacterial is selected against weaker bacterial

Genetic Drift as an Evolutionary Force Becky Gonzalez Genetics 2450 Lab Section 1262 March 2‚ 2011 Genetic Drift as an Evolutionary Force Genetic drift‚ along with natural selection‚ mutation‚ and gene flow‚ is one of the basic evolutionary forces of evolution. Evolution is the method by which allele frequencies in a population change over time. This process can be random‚ where the changes occur through genetic drift (Hahn and Bentley 2003)

affliction‚ adversity‚ misery‚ etc. The word survives is of the Latin origin from the word Supervīvere super- (over‚ beyond) and –vīvere (to live). The phrase survival of the fittest was used in the seventeenth century to replace Darwin’s term natural selection‚ “to kill or be killed”. Although the term survival has various meanings‚ in reference to Suzanne Collins’ The Hunger Games‚ survival is used a verb to describe the act of surviving. Katniss enters the hunger games as a volunteer‚ and is expected

The Major Theories of Biology Evolution by natural selection: This theory came about as a result of Charles Darwin trying to find an explanation for “why there are so many different living beings on earth?” (Pruitt‚ N. L.‚ & Underwood‚ L. S. (2006). His theory contains two parts‚ the first part states that species change over generations. The second part states that what causes this change is natural selection. Inheritance: This is another theory by Gregor Mendel. He

Therefore‚ in response to environmental pressures‚ the frequency of heritable characteristics will change from one generation to the next‚ and evolution by natural selection will take place. …humans display greater genetic unity than most other species‚ which has led many to assume that human evolution ended with the origin of modern humans The modern theory of evolution—built on a vast array of supporting

Charles Darwin in his novel‚ on The Origin of Species‚ educates the world with one of the greatest scientific findings of the late eighteen hundreds being the theory of natural selection. Darwin’s‚ The Origin of Species has influenced society in many ways; creating a new theory in human society in regards to Social Darwinism‚ implementing controversial topics on religion and becoming the basis and starting point for the field of biology. This idea is Darwin’s attempt at an explanation on how the

In “Selection Does Primarily Operate on Genes”‚ Carmen Sapienza argues that selection primarily acts upon genes. Sapienza supports this notion by defining Natural Selection as a process that allow one to distinguish between “biological entities”‚ and this process confers a reproductive advantage upon one of the “biological entities”. For Sapienza‚ this biological entity is defined primarily as the gene. Sapienza argues that genes are directly the main targets of selection. For direct selection‚ Sapienza
