History

Originating from cynodonts in the Late Triassic, mammals achieved modern diversity during the Cenozoic era, filling ecological niches left by dinosaurs.

Examples

Extant species are divided into 27 orders, including Rodentia, Chiroptera, and Primates.

Overview

Mammals are the only living members of the Synapsida clade. They are defined by the presence of mammary glands, a neocortex, and specialized ear structures.

Importance

Beyond ecological roles, mammals are essential to human civilization. Domestication facilitated sedentary societies, while their study provides insights into biology and evolution.

How It Works

Mammalian physiology supports high intelligence and complex social structures. Most are viviparous, utilizing a placenta for gestation, with the exception of monotremes.

Frequently Asked Questions

What are mammals?+
Mammals are animals like humans, dogs, and whales that are warm-blooded and take care of their babies by nursing them.
Why do mammals have a neocortex?+
The neocortex is a part of the brain that helps mammals think and learn, showing their complex neurological development.
How do mammals keep their babies warm?+
Mammals are warm-blooded, meaning they can keep their body temperature steady, which helps keep their babies warm and healthy.
What does it mean that mammals nurse their young?+
Nursing means mothers give milk from their breasts to feed and care for their babies, a special way mammals protect them.
Are all mammals the same size?+
No, mammals vary a lot in size—from tiny mice to huge whales—showing their diverse physiological adaptations.
