Animal Science help - reproductive female system?

Question

Please pick the anatomic features of the female reproductive system in any species of animal and discuss how it has been adapted to fit environmental pressures.

A hand to get this started or some links would be nice... I can add to it to fit what I need...

Answer 1

Female lions are polyestrous, breeding throughout the year and peaking in the rainy season. Female lions tend to have cubs every 2 years. However, if a female's cubs are killed (usually by an intruding male lion), then the female comes into estrus early and has more cubs. Females are able to breed at 4 years of age and males at 5 years.
