>>13858254Macro-evolution retards pretending there are two separate species despite no post zygotic barriers. It frequently leads to hilarious nonsense situations like your bird but they have to keep up the facade that speciation is easy and happens all the time as a big cope, so these situations are usually just ignored, or they come up with lunacy like epigenetics/convergent ebolution like these morons
>>13858267 >>13858271Didn't read the article due to pop sci but odds are there was just a different mating call in the "extinct species", leading to a pre-zygotic barrier and the nonsense idea that makes them a different species, that lineage went extinct, and coincidentally the same genes were in the greater population still and became isolated again by simple coincidence. Viola, the pretend "new species" returned.
