BBC Radio 4 - In Our Time, Hybrids

Melvyn Bragg and guests discuss how parents from different species can reproduce

Melvyn Bragg and guests discuss how some genetically different parents - from different species - can have offspring and what that says about the origin and evolution of species

Melvyn Bragg and guests discuss what happens when parents from different species have offspring, despite their genetic differences. In some cases, such as the zebra/donkey hybrid in the image above, the offspring are usually infertile but in others the genetic change can lead to new species with evolutionary advantages. Hybrids can occur naturally, yet most arise from human manipulation and Darwin's study of plant and animal domestication informed his ideas on natural selection.
