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 construction 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 collar brush aside be accounted for in the following c keepgories: genetically ground, environmentally assemble and sampling technique. Genetically establish reasons for variation fall 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 shift in DNA restoration and this change affected the lengthiness of the anchovy. This variation would baffle been fostered genetically, so the reason for this variation would capitulation under the genetically based category. Variations could have also been fostered repayable to environmental reasons. Possibly, a piranha might have come along that only ate the bigger fish, therefore killing off all of the larger fish in the species. uncounted other environmental factors could have influenced the amount of variation that we saw. Also, slightly of the variation may have arisen from our sampling technique. We had multiple classes tax 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 prat see in the to a higher place graphs, from each one species tended to have a bell curve in the measurements of their lengths. in that location 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...
