Kind: research · Impact: low

## In brief

- A study in Proceedings of the Royal Society B reports that decorative mating traits tend to evolve faster than physical combat weapons.
- The findings combine a mathematical model with data from 531 species across 10 animal groups.
- The source is a short PsyPost summary; the excerpt does not give further details of methods or effect sizes.

## Why it matters

The result offers a comparative test of how sexual selection shapes different kinds of traits across many animal lineages, which can inform how researchers interpret trait evolution.
