New Study Reveals High Energy Costs of Reproduction in Animals

Research shows mammals, especially humans, invest significantly more energy than previously thought in creating offspring.

Indirect metabolic costs account for up to 90% of total reproductive energy in mammals.
Humans rank among the top species in energy expenditure for reproduction, with 96% of costs being indirect.
White-tailed deer have the highest recorded indirect energy costs among the studied species.
The findings challenge traditional biological models and have implications for understanding animal growth and adaptation.
Climate change could further increase reproductive energy costs, impacting biodiversity and species survival.
