Colonisation routes, habitat shifts, disruption of populations by volcanism, dispersal by massive landslides, and other relevant aspects for adaptive and non-adaptive radiation, are largely discussed and confronted with previously published data referring to other groups of beetles or to other biological organisms (spiders, bush crickets, plants, etc.).

The findings, says Farrell, «show how moving into a new environment, where there's no competition, can free you for an explosive, adaptive radiation.»

That is among the conclusions in a new study testing the importance of «first arrival» in controlling adaptive radiation of species, a hypothesis famously proposed for «Darwin's Finches,» birds from the Galapagos Islands that were first brought to scientific attention by Darwin.

Paradoxically, because Lake Tanganyika is already considered the poster child for studies of evolutionary adaptive radiation — only not because of its eels.

Darwin also found evidence for his theory in examples of convergent evolution, co-evolution and adaptive radiation.

This allowed the group led by Ole Seehausen (head of the Fish Ecology and Evolution department at Eawag and Professor of Aquatic Ecology at Bern University) to provide strong evidence for his theory that hybridization between divergent species, in conjunction with ecological opportunity, can facilitate rapid adaptive radiation.

At the time this was probably rather useless genomic variation, but has now become incredibly beneficial millions of years later when the opportunity for major adaptive radiations arose, changing the way we think about evolutionary processes.»

Nature 2014, 513, 375 - 381 — Nature News & Views Cichlid fishes are famous for large, diverse and replicated adaptive radiations in the Great Lakes of East Africa.

This phenomenon, commonly called adaptive radiation, means that the original (homogeneous) species eventually divides into subspecies that can be very different in physical appearance - so - called phenotypic differences - because they have been selected for and adapted to different habitats or specific niches.

There could be three evolutionary processes could explain this adaptive radiation of hominins: 1) the occupation of novel niches for species living in a highly productive but spatially constrained region when there are deep fresh water lakes in the EARS [46] and 2) the lakes themselves creating spatial structure producing population isolation and vicariance and 3) repeated periods of increased resource availability stimulated adaptation and radiation followed by periods of environmental stress when the lakes rapidly dried up imposing strong selection pressures [28].
