Although there seems to be a minor role for sexual selection as well.

An interesting goose paired to a Tundra Bean. The all pale peachy-pink bill, white halter and small dark spots on the upper belly perhaps point to it being a Tundra Bean X Russian Whitefront hybrid rather than an aberrant Tundra Bean. With Ash McElwee and Graham Fellows

Every year Bionieuws hosts a Darwin Café. This year, they invited philosopher Gerard Jagers op Akkerhuis. What a missed opportunity! His “theory” is philosophical handwaving with no empirical support, while there is so much real evolutionary research out there.

I am currently looking into owl hybrids, which involves diving into some grey literature. Look at this wonderful family: Eurasian Eagle-owl, Great Horned Owl and their offspring. 😀

No, they don't. The researchers combined (ethno)species lists from local communities with body mass data from AVONET.
