Predatory mammals show diet-linked shifts in evolutionary conservation, with vertivores and invertivores differing significantly in conserved genes and GO categories relative to herbivores.
- Why it matters: Prior work linked diet to selection and gene evolution mainly using broad trophic labels, leaving uncertainty about whether carnivory signals reflect prey type, especially invertivory.
- What they did: The study split carnivores into vertivores versus invertivores, then compared evolutionary conservation across genes and GO categories using herbivores as the reference.
- The result: Lineages with predatory diets show increased conservation in lipid and amino acid metabolism versus herbivores, and combined carnivore results resemble invertivores more than vertivores, implying earlier carnivory signals may reflect invertivory.
