Which of the following statements is FALSE about the long-term evolution experiment (LTEE) that you learned about in the Case Study 2 content? a) The LTEE is different from most other studies of evolutionary change within lineages because the "frozen fossil record" allows recovery and further study of ancestors that lived many thousands of generations ago. Ob) The LTEE shows that the evolution of a new trait may occur in several steps, the first of which is the origin of mutations that arise because someday they will make it possible for new traits to manifest and be selected for in a given environment. c) The LTEE reinforces the notion that whether a given mutation is beneficial or deleterious depends on the environment in which the organism lives. O d) The LTEE shows that traits can evolve independently and even repeatedly, but that there are also signs of historical contingency in that they do not necessarily evolve in exactly the same way from a genetic standpoint. e) The LTEE…

Please answer the question below; specifically "what are the four observations that inexorably led to the conclusion that species evolve by natural selection?" Thank you so much.
Geographic isolation is an isolating mechanism in nature. Over long periods of time, it can lead to speciation. As the name suggests, geographic isolation is when populations of a species become separated geographically. This could also happen from the founder effect, where a small group breaks away from a larger population and establishes a group in an isolated area. Isolation could also occur when a geographic event, like an earthquake or a landslide separates a population. Once the populations are separated evolution can occur through multiple mechanisms. Natural selection could act on each population, where some individuals have favorable traits for survival. Genetic drift can occur, where genotypes become more common due to random chance. These mechanisms can lead to each subpopulation becoming so different, that they can no longer interbreed and are considered separate species.
