The standard classification system used by biologists today groups and classifies organisms on the basis of similar physical traits. this system was first developed by carl linnaeus. at the time of his work, there were other methods for grouping organisms that were based on similar habitats, similar diets, or similar behaviors. why is linnaeus's system the most useful one to biologists today?

Azoologist is studying four very closely related feline species. she wishes to compare their gestation periods. an observational study is conducted where the zoologist observes the gestation period of 50 randomly selected felines in each species. a one-way anova test is run to test the hypothesis that the average gestation period is the same for each of the four species. a level of significance of 0.05 is used, and a p-value of 0.01 is calculated. based on this result, the conclusion that can be drawn is that:
