Fitness effects of grandparental investments in contemporary low-risk societies
Published online by Cambridge University Press: 09 April 2010
Abstract
Coall & Hertwig (C&H) suggest that, because grandparental investments do not impact on child mortality in low-risk societies, fitness effects are not plausible any more. We found that grandparental investments could very well alleviate contemporary constraints on fertility. Cultural factors may influence both the occurrence and impact of grandparental investments.
