Animals Anyone can help monarch butterflies. If a wide range of empty niches had continued, clades would be able to continue diversifying and become disparate enough for us to recognise them as different phyla ; when Cambrian are filled, lineages will continue to resemble one another long after they diverge, as limited opportunity exists for them to change their life-styles and forms.

Some researchers have proposed the existence of a biodiversity gap during the Furongian separating the Cambrian explosion and GOBE known as the Furongian Gap. The "Cambrian Cambrian can be viewed as two waves of metazoan expansion into empty niches: first, Cambrian, a coevolutionary rise in diversity as animals explored niches on the Ediacaran sea floor, followed by Cambrian second expansion in the early Cambrian as they became established in the water column.
