Is hermaphrodism less common in animals because it is energetically more costly? George Jarvis and @djmmeeg.bsky.social have analysed 536 species of marine invertebrates and found that hermaphrodites require approximately 27% less energy than gonochores on average.

Was Darwin wrong? Hermaphrodites found to be more energy efficient than animals with two sexes

Excited to share our study testing competing theories on the energy dynamics of hermaphroditism! Grateful to @djmmeeg.bsky.social for guidance, to Thomas Brey for metabolic rate data, and to Deborah Charlesworth for feedback. Thanks also to the editors and reviewers at Proc B. @royalsociety.org
Darwin speculated that it was energetically costly to be an hermaphrodite. He thought that might explain why they were relatively rare in animals. Our paper out today tested this conjecture for the first time.

Another cool genome assembly: The first phased, annotated, chromosome-level assembly for a reef-building tubeworm, Galeolaria caespitosa! The species has 11 autosomal chromosomes and no sex chromosomes.
