Animals raised by two parents grow better

ANIMALS raised by two parents grow better and have higher survival rates than offspring reared by a single male or female, a study has found.

Researchers from the universities of Glasgow and Edinburgh studied burying beetles and compared the survival and growth of the young when they were reared by one or both of their parents. It was found that larvae reared by parents who worked together were larger at the end of the parental care period than those reared by parents who worked alone. The larvae reared by two parents were also more likely to survive to adulthood.

The team discovered this was the case even though males “exploited” females when co-parenting.

The study found males and females gave equal care when raising young alone, but when raising young together, males gave less care, forcing females to compensate.

Many species have “biparental care”, when parents co-operate to raise offspring.
