anagenesis
_____ is when a single species evolves into a different species.
Anagenesis is a type of evolution that occurs within a single lineage or species over time, where the species gradually transform into a new one. In other words, anagenesis is a form of evolution that involves changes in a species’ genetic composition, morphology, and behavior, which can lead to the emergence of a new species.
An example of anagenesis can be seen in the evolution of horses from their earliest form – Eohippus. Over time, the horses gradually evolved with significant changes in their morphology, such as increased body size, longer legs, and modified teeth. These changes have allowed horses to adapt to different environmental conditions and selective pressures, leading to the emergence of several distinct horse species.
Anagenesis can occur through various mechanisms, including natural selection, genetic drift, mutation, and hybridization. These mechanisms can act together or individually, leading to the gradual transformation of a species. Anagenesis is essential in the study of evolution as it helps scientists understand the mechanisms that drive the evolutionary process and how species emerge and diversify.
