Over the past ten years, the DNA sequencing revolution has revealed that mating between two different species, i.e., hybridization, once considered rare, is actually widespread across the tree of life. This came as a surprise—hybridization was considered mostly detrimental since offspring are not always viable and can be infertile, like mules. However, many studies showed that hybridization could have beneficial consequences and help populations adapt to new environments.
