ANT BRAINS REVEAL HOW EVOLUTION TURNED HUNGER INTO PARENTING

Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older.

All Top News -- ScienceDaily reports that ant parenting may have evolved from the same brain systems that once controlled hunger.

The report adds: Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older.

Similar signals are involved in mammalian caregiving, suggesting that evolution may have followed the same basic blueprint across very different animals.
