* [[Adaptive radiation]]s such as the [[Cambrian Explosion]].
* Changes in [[Biodiversity#Evolution and history|biodiversity]] through time.
* [[Evolutionary developmental biology|Evo-devo]] (the connection between evolution and [[developmental biology]])

* [[Extinction event|Mass extinctions]].
* Estimating [[diversification rates]], including rates of [[speciation]] and [[extinction]].
