Biologists holding the opposing viewpoint consider the world today to be the most perfect template, no calculations needed; just take all the currently discovered microorganisms, animals, and plants and dump them in all at once, letting them develop over time is sufficient. They believe that research for the sake of research is putting the cart before the horse!
"You can't put roaches in there! I mean, those specific kinds of roaches! You son of bitches actually want to toss those damned roaches and mice into our precious experimental habitat! I will not agree to this!"
"Orf! You well know that roaches are important decomposers in the natural food chain, how can you be so prejudiced? To think you call yourself a biologist!"
