Všetky cicavce zdieľajú určité vlastnosti, ako je teplá krv a chrbtica. Napriek ich podobnostiam však tieto stvorenia majú aj veľa biologických rozdielov – a jedným z najpozoruhodnejších rozdielov je spôsob, akým rodia. Kate Slabosky podrobne popisuje metódy pôrodu placentovcov, vačkovcov a vtákozobcov.

All mammals share warm blood and backbones, but the ways they bring new life into the world are strikingly diverse. A newborn blue whale can already swim at 23 feet long, thanks to months sustained by its mother's placenta. Marsupials like kangaroos give birth to tiny, vulnerable babies who finish developing inside a pouch, while monotremes like the platypus defy expectations by laying eggs, yet still nurse their young. These varied strategies show how mammals adapt to thrive in many environments.
