What should I ask Richard Prum?

I will be doing a Conversation with him, here is part of his Wikipedia page:

Richard O. Prum (born 1961) is William Robertson Coe Professor of Ornithology, and Head Curator of Vertebrate Zoology at the Peabody Museum of Natural History at Yale University.

Prum describes himself as “an evolutionary ornithologist with broad interests in diverse topics,” including phylogenetics, behavior, feathers, structural coloration, evolution and development, sexual selection, and historical biogeography.

Prum holds that birds are the living descendants of theropod dinosaurs, a once disputed finding that is now almost universally accepted in the ornithological and evolutionary biology scientific communities.

Prum grew up in rural Vermont and took his bachelor’s degree at Harvard in 1983, and received his Ph.D. in 1989 from the University of Michigan. After gradually losing his hearing throughout the early 1990s due to illness, Prum moved from primarily doing field work to conducting research on plumage pigmentation, feather evolution, and Darwin‘s sexual selection theory. He released a book in 2017 on the role of beauty in natural selection: The Evolution of Beauty: How Darwin’s Forgotten Theory of Mate Choice Shapes the Animal World – And Us.

So what should I ask him?
