What data provide support for the plate tectonic theory? detailed research of the ocean floor shape of the continental coastlines matching up together lava flows that match up on different coasts of different continents rock layers that match up on different continents

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection

In the practice of science, this type of reasoning is used to develop explanations.

Based on the number of offspring they produce at one time organisms are classified into two categories many offspring at once and a few at a time sort the carry sticks based on the category they describe
