Description
Notes: 9/21 Speciation Hybrids - Hybrids are adapted to intermediate niches, normally there is none in nature Reinforcement – when hybrid is adapted to in between parent’s niches, and that intermediate niche doesn’t exist Ex.) If a large ground finch has a certain mutation that makes it attracted to medium ground finches it will mate with only medium finches. Their hybrid offspring will also have that attraction mutation. If the hybrid isn’t viable/has no niche, the gene for the attraction mutation will die off as well as the hybrid. Ecological Concept of Species - There is natural selection against hybrids/ most hybrids aren’t viable or a strong “species” (aka no one wants to mate with them, they don’t fit anywhere in the environment) Ex.
