Herders sometimes favor hybridization because genes from wild progenitors are thought to enhance the hardiness of domestic stock.

Baker notes that the lineage that led to blueberries, for instance, is the result of an ancient hybridization between dogwoods and the ancestors of coffee plants, daisies, and mints.

This phenomenon, known as subspecies hybridization, can be an important path for species to adapt to a changing environment.

The work contributes to a growing notion among evolutionary biologists that hybridization can sometimes increase, not decrease, the diversity of species within an ecosystem.

Arabica formed as a natural hybridization between Coffea canephora and Coffea eugenioides, whereupon it received two sets of chromosomes from each parent.
