Diversity
This article should probably put more emphasis on the idea that adaptive radiation is one of the leading causes of biological diversity. Through adaptive radiation, speciation occurs which creates a variety of new species with a variety of new traits. Even within a single population, adaptive radiation can cause that population to diversify genetically and morphologically. Diversity is one of the major observable results of adaptive radiation. — Preceding unsigned comment added by Behrens.42 (talk • contribs) 06:04, 1 October 2014 (UTC) --Behrens.42 (talk) 18:23, 13 October 2014 (UTC)
Adaptive radiation is never an intra-species phenomenon. If you want to describe genetic diversity within a population, you can talk about divergent selection, or multiple niche polymorphisms, etc. But you wouldn't use the term "adaptive radiation" until speciation happens Jesseseeem (talk) 23:06, 29 July 2020 (UTC)
Darwin's Finches
This page could also benefit from a strong example such as Darwin's finches. They probably best exemplify the process of adaptive radiation. As Darwin's finches were separated among the islands of the Galapagos, they evolved due to the differing environments they inhabited. One major change due to the divergence of the species involved their beak shape which changed according to the method used to obtain food — Preceding unsigned comment added by Behrens.42 (talk • contribs) 05:04, 1 October 2014 (UTC) --Behrens.42 (talk) 18:24, 13 October 2014 (UTC)
Empirical Methods Used to Study Adaptive Radiation
This page could benefit from a discussion of how adaptive radiation has been studied in the past. There are four main approaches which include fossils, phylogenetic comparative methods, microevolutionary studies of extant taxa, and adaptive radiation in the lab. Fossils allow us to study the changes in the clade of an extinct species. Phylogenetic comparative methods study the increasingly complete sets of phylogenies that have been developing over the past few decades. Microevolutionary studies of extant taxa looks into the specific traits and processes of a taxa to determine whether any of these factors could affect adaptive radiation. And finally adaptive radiation in the lab allows for experimental flexibility and makes it easier to control certain factors when studying adaptive radiation. — Preceding unsigned comment added by Behrens.42 (talk • contribs) 04:58, 1 October 2014 (UTC) --Behrens.42 (talk) 18:24, 13 October 2014 (UTC)
