Hypothesis Testing The sole purpose of hypothesis testing is to determine whether or not research that has been collected is proved or disproved; usually allowing up to a 5% error factor. By using this 5% margin of error a researcher can consider the question of research being conducted is proven. There are five steps to be followed in doing hypotheses testing. The steps are: developing the research question‚ specifying between null and alternative hypotheses‚ calculating the statistic‚ computing

Polyandry is a mating system where females mate exclusively with a group of males that only mate with the one female. This is different from polygyny‚ which can be thought of as the opposite of polyandry as one male mates exclusively with a group of females. Promiscuity can be defined as a mating system where both males and females mate with several individuals‚ and there is no long-term or pair bonding. Each mating system offers certain costs and benefits to each sex‚ and typically arise due to

instrumental for the RNA World Hypothesis ("Sidney Altman: The RNA World"). This hypothesis stated that early life started with RNA as they possess the ability to serve as a catalyst as well as contain genetic information. The RNA was able to spontaneously form under natural processes‚ which eventually replicated into all sorts of life. This paper will analyze the theoretical and experimental support for this hypothesis and comment on the plausibility of the RNA World Hypothesis. The RNA World theory is
