Beetles: Older males 'make better dads'

1 post in this topic

Mature males make "better" fathers in burying beetles, a study suggests.

Researchers found older males work harder at parental care and mating compared with younger males.

Older males also maintained their parenting efforts when they were uncertain of their paternity, whereas younger males decreased their activity.

The research provides new evidence for the theory that older male animals, having less chance of reproducing again, invest more in parental care.
