To what extent do Moreau's experiments suggest the dangers of toying with nature?

Despite his socialism, which relied on a hope in social progress through the use of reason, Wells was tapping into a common concern about the amoral march of "progress," namely the risk that it can corrupt and overwhelm the natural sensibilities of men with its promises of shiny, efficient perfection. Many people in his time worried that man was overstepping his authority and entering the domain of divinity. Moreau's vivisections express the dangers of science and technology. Doctor Moreau's speech to Prendick in defense of his activities is especially relevant: as a man of reason he claims, among other things, that pain and pleasure are irrelevant. As well he created strains of DNA that were potentially harmful to the species he created and others around it.
