After more than two decades of studying wild spotted hyenas in Kenya, scientists from the University of Michigan have uncovered a secret about this matriarchal species.
Female hyenas often provide their offspring with a “strong start” by passing on hormones that stimulate aggressive behavior, helping them succeed in the struggle for survival. This can be considered a gift that the mother hyena gives to her young.
Scientists have demonstrated that during pregnancy, mother hyenas possess higher than normal levels of androgens, the hormones typically associated with “males.” The cubs inherit these hormones and become stronger as a result.
Spotted hyenas operate under a matriarchal system, where females are typically “masculine,” larger, and hold more power than males. However, they still retain their distinct female characteristics.
If a mother hyena holds a high status within the clan, her female cubs will benefit from her hormones, becoming proficient hunters and achieving a status that rivals their mother’s.
Male hyenas whose mothers are “top dogs” are also significantly stronger and more aggressive.
