## In brief

- The article reports evidence in fish for a nutrient struggle between mothers and their embryos.
- Evolutionary theory predicts that mothers must keep some essential nutrients for themselves to survive pregnancy, while developing babies benefit from taking as many nutrients as possible.
- The sources provided do not give further details on the study's methods, species or findings.

## Why it matters

It offers empirical support for the theory of maternal-fetal conflict over resources, which is relevant to how science readers understand the evolution of pregnancy and nutrient allocation.
