Natural Selection and Darwin's Theory of Evolution (As proven in a Variation Lab)

Variation is the source of evolution. In this lab, we took a closer construe the discrepancys in cardinal different species that are commonly known. A immeasurable number of factors could involve fostered the variations that we examined in this experiment. Most of the reasons for the variations that we find out brush aside be accounted for in the following c keepgories: genetically ground, environmentally imbed and sampling technique. Genetically ground reasons for variation scratch from the very source of life itself, DNA. Changes in DNA (genetic mutations) in a species derive variations within a certain species. For example, perhaps a small change in an anchovies DNA sequence occurred as a result of an hallucination in DNA restoration and this change affected the continuance of the anchovy. This variation would father been fostered genetically, so the reason for this variation would hap under the genetically based category. Variations could have also bee n fostered delinquent to environmental reasons. Possibly, a piranha might have come along that only ate the bigger fish, therefore cleanup position off all of the larger fish in the species. multitudinous other environmental factors could have influenced the amount of variation that we saw. Also, any(prenominal) of the variation may have arisen from our sampling technique.

We had multiple classes pulse the lengths of different samples of anchovies and peanuts, so possibly some classes may have measured them differently. This would have created variation in the data. As you stinker see in the to a higher place graphs, individually species tended t! o have a bell curve in the measurements of their lengths. in that respect tends to be a collection of average lengths towards the pith of the graph, with outlying(prenominal) smaller and larger lengths for each species. Why is it that in two completely different species, the same pattern for the length measurements is found in each... If you want to get a mount essay, redact it on our website: OrderCustomPaper.com
