Briefings

A study by Smit et al. at the Max Planck Institute and University of Turku found female mandrill monkeys are more likely to miscarry when nursing an infant, suggesting a physiological trade-off between current and future offspring. The research was published in PLOS Biology in November 2026.

Key points

• Female mandrill monkeys experience higher pregnancy loss rates when simultaneously nursing an infant.
• This phenomenon likely represents a physiological trade-off between caring for current and future offspring.

Context

Research from Germany and Finland published in PLOS Biology explores reproductive trade-offs in primates, specifically mandrills, to understand evolutionary mechanisms.

Limitations

Evidence is limited to a single study; specific dates, exact numbers, and geographic locations are not provided in the source.
