Natural Selection Experiment

INTRODUCTION Natural selection theory is based upon the supposal that allorganisms stimulate more(prenominal) offspring that can brook in an environment on account of limited resources. The offspring that can hold up long enough to reproduce can pass on the particular forms of variation to their offspring. While the less favourable or adaptive traits are often lost form the divisor pool. In other words, we can say that the environment quit behind contribute effects on phenotypic characteristics of an organism. In this investigation students pass on act as the predators, armed with all tensile knives, forks and removes will try to capture 3 divers(prenominal) feast species; kidney beans, black beans, and set forth peas. HYPOTHESIS My assumption for the quality of objective which would credibly to survive is split peas as they are lower-ranking and more in number, therefore be it harder for the predator (mouthpieces) to obtain. Whereas, the typesetters c ase of predate that are less likely to survive is kidney beans, as they are big in surface and easier to grab. My hypothesis is that the type of predator which would likely to win the alimentation competition is the spoon(s), go the knife(s) would be the least to win.

MATERIALS AND METHOD: Students actively participate as one of three predator (either knife, spoon or fork) species as they attempt to capture as legion(predicate) objectives/individuals (kidney beans, black beans and split peas) as possible of four prey species. In drift to survive each predator must obtain more food, those who receive less food than 50% of population will die. When time is started, each pr edator will try to pull in as many beans as! possible. At the end of 2 minutes, time is called and the feeding stops. all(prenominal) predator counts the no of prey (beans) he/she has picked up. The half(a) predator that picked up the most beans survived, the half who did not die. For the second greneration, the surviving predators (which forthwith is only half) repeats the same(p) process. The process continues until the third...If you want to get a beneficial essay, cabaret it on our website: OrderEssay.net
