During the customs process, importers often simply list their goods as shells, and the few inspectors at most ports of entry are expert enough to identify protected species. Disruptive selection occurs when individuals with either extreme of an inherited trait have an advantage over individuals . Founder events occur when a single or small group of individuals establishes an isolated population. Treadmills burn slightly more calories than stationary bikes, though the difference is negligible. The subsequent population of blackbirds on the island displays lower genetic diversity than the original population. Which mechanism of evolution is likely responsible for this phenomenon? Finally, as with treadmills, if you enjoy exercising in nature, indoor stationary biking may not be as appealing as cycling outside.
