For a species to evolve, certain factors must be in place. Many wonder if natural selection is a way to see that a population is on the verge of early speciation. We know that evolution, ecology, natural selection and the environment are all linked to each other. But what makes a species what it is? What allows them to inherit certain traits? This article will focus on the study of Beren Robinson who chose to study the threespine fishes of coastal British Columbia lakes. Threespine Sticklebacks Brenan Robinson chose to study fish known as threespine sticklebacks of the Gasterosteus family. He discovered that they had undergone a period of rapid speciation and that those inhabiting the lakes of coastal British Columbia, specifically those inhabiting Cranby Lake, were among the youngest species on Earth. He believed that no more than two species of the same fish could be present in the same lake. Judging by what he must have already observed, he came to the conclusion that he needed to compare the different species that evolved independently of other pairs. Question and Hypothesis Robinson wondered whether or not the constraints imposed by distinct environments were responsible for the evolution of species. the pairs of species he found in the different lakes. He hypothesized that fish represented certain phenotypes that were products of natural selection, favoring divergence within populations. He questioned whether or not divergence could occur when species faced trade-offs, which involved different tasks for different species depending on the environment they were in (Smith and Smith, 2009). One of his observations was that the middle of the paper was stronger than the other or healthier than the other. If there are greater numbers of one species than another, then I would also question that and hypothesize that it might also have something to do with their eating habits. Conclusion Brenan Robinson's study is a good way to examine how morphological differences occurred with threespine spruce trees. These are the kinds of studies that open the door to further research. The questions don't end where Brenan Robinson's study ended. There is much more that scientists can glean from a single study. This study is a good study for people working in multiple scientific fields and will likely be studied again with different hypotheses and questions in the years to come.
