Some biologists, such as Jack Cohen, believe this assumption too restrictive and unimaginative ; they see it as a form of circular reasoning ( see Alternative biochemistry, a speculative biochemistry of alien life forms ).

Some biologists dislike the term " preadaptation " because there is a common tendency to misunderstand it as implying teleology, an intentional plan.

Some chemical biologists use automated synthesis of many diverse compounds in order to experiment with effects of small molecules on biological processes.

Some biologists consider it to be a subspecies of P. sungorus.

Some biologists argue that it is not herbivorization alone that is threatening the flora, but a number of other ecological factors including zoochory and nutrient cycling.

Some biologists conduct laboratory experiments involving animals, plants or microorganisms but biological research also takes place outside the laboratory and may involve observation rather than experimentation.
