Excellent new paper from Kyle David finding evidence for a latitudinal gradient of polyploidy in animals. This is similar to what has been observed in plants for many years! Really wonderful! Also good to see our recently published Animal Chromosome Count Database used for the analyses!

@MikeBarker Nice! "These results contribute to a model of evolution wherein the broader genomic toolkit of polyploids facilitates adaptation and ecological resilience, enabling polyploids to colonize new or rapidly changing environments."
@marcrr @MikeBarker I wish I believed the general #polyploidy-diversification story line, but there are, e.g., “hyperdiverse” angiosperm lineages (like Rubiaceae) without events in/near their stem lineages… there’s more to the story. Of course, some Rubiaceae from extreme environments are neopolyploids 🤣
