Science Paper Admits Evolution Mechanism of “Adaptive Radiation” Lacks Empirical Evidence

A recent article in Science titled “Adaptive Radiation: Contrasting Theory with Data” admits that the evidence documenting the precise workings of a key macroevolutionary mechanism — “adaptive radiation” — is missing. The article concedes that “how exactly radiation occurs, and how it differs among taxa and in different settings, as well as why some lineages radiate and others do not, are still unclear.” When studying evolutionary biology in college, I learned that new types of organisms have commonly appeared abruptly in the history of life. Since Darwinian evolution is supposed to proceed by “numerous, successive, slight modifications,” this data made little sense in the light of evolution. Our professors always reassured us that rapid evolution or abrupt appearance of major Read More ›
