Ant brains reveal how evolution turned hunger into parenting
✦AI Summary
A study on clonal raider ants suggests that parental care behaviors evolved by repurposing ancient neural pathways originally used for hunger and feeding. This indicates that evolution often adapts existing biological systems rather than creating new ones from scratch.
For much of evolutionary history, many animals reproduced and then left their offspring to survive alone. A study published in Nature now offers a possible explanation for how caregiving emerged from those distant, nonparental beginnings.
