Evolutionary Correlation between Size and Temperature

Abstract


Throughout different climates and on different continents, there are multiple species of badgers with different qualities and characteristics. It has been found that the species of badgers living in colder climates are generally larger with a smaller surface area to volume ratio (French, 2014). This occurrence has not been researched previously because of the difficulties of acquiring sample that will accurately allow one to find the answer as to why some species are bigger. We attempted to solve this by running an experiment where five clay models of varying sizes were heated up and then allowed to cool while the rate of cooling was being measured. After collecting data, we came to the conclusion that the species of badgers living in colder climates have evolved to have larger bodies due to the fact that their larger bodies allow for a smaller surface area to volume ratio and therefore a greater ability to retain heat. Furthers the understanding of thermoregulation and how climate affects the evolution of the species.
