WebFeb 1, 2024 · The concept of ‘key innovations’ – the evolution of phenotypic traits that permit shifts into previously inaccessible ecological spheres – has been a powerful idea in evolutionary biology. The expectation that key innovations should result in increased species richness or adaptive radiation is conceptually problematic. WebAdaptive Radiation. In some cases, a population of one species disperses throughout an area, and each finds a distinct niche or isolated habitat. Over time, the varied demands of their new lifestyles lead to multiple …

In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
