Evolution: replacing genes and traits through hybridization.
The role of hybridization in evolution has been debated for over a century. Recent molecular genetic studies indicate that hybridization is surprisingly frequent in natural populations, and that it may allow populations to regain traits that have been lost and possibly to replace damaged alleles with functional copies from related species.
