WebMar 8, 2024 · For example, levels of introgression between Darwin's finch species with different sized beaks are thought to be highly adaptive during severe droughts. In this case, beak size is so highly selected during drought seasons that hybrids are favoured and gene flow levels between species greatly increase [13,14].
