Answers
GPT-4o mini
Mammals are a diverse group of animals characterized by several distinct features. Here are four key features of mammals:
1. **Hair or Fur**: Mammals have hair or fur at some stage of their life cycle, which provides insulation and helps regulate body temperature.
2. **Mammary Glands**: Female mammals possess mammary glands that produce milk to nourish their young, which is a defining characteristic of the group.
3. **Three Middle Ear Bones**: Mammals have three bones in the middle ear (the malleus, incus, and stapes) that are involved in hearing, allowing for better sound transmission.
4. **Warm-Blooded (Endothermic)**: Mammals are warm-blooded, meaning they can regulate their body temperature internally, maintaining a relatively constant temperature regardless of the environment.
These features contribute to the unique biological and ecological roles that mammals play in various ecosystems.
