Animals have genetic mishaps just like people, and one such case has been discovered in the Mombo area of Botswana‘s Okavango Delta. Maned lionesses have been regularly spotted there since 2002. These maned lionesses look exactly like males therefore making them safer, since other animals are more scared to steal food or attack the pride. This phenomena most likely occurs because the fetus is exposed to higher than normal androgen levels ( male hormones such as testosterone ) during gestation period. The president of the big-cat conservation group Panthera, Luke Hunter believes that there's a possibility of the lion population in that area being genetically predisposed to this phenomena.
