Evolutionary biology
The junkyard tornado argument is rejected by evolutionary biologists, since, as the late John Maynard Smith pointed out, "no biologist imagines that complex structures arise in a single step." Evolutionary biology explains how complex cellular structures evolved by analysing the intermediate steps required for precellular life. It is these intermediate steps that are omitted in creationist arguments, which is the cause of their overestimating of the improbability of the entire process.
