Expert reveals the patterns of diversity in insects

Looking around at the natural world, have you ever wondered why some groups of organisms contain huge numbers of species while others are seemingly barren? Take insects as an example, animals which evolved around 480 million years ago. There are perhaps 6 million species living in all manner of environments, and occupying an incredible diversity of niches. Have you ever wondered why some groups of organisms contain huge numbers of species while others are seemingly barren? Plants have had a species production rate more than twice that of animals, while complex organisms (multicellular eukaryotes) have produced new species at a rate almost 10 times that of simpler one (protists and prokaryotes). Sex seems to have been a major catalyst for increasing the rate at which new species formed, perhaps explaining its success as an evolutionary strategy.
