**Youngone Giving Animal: Mammals**

Mammals are a diverse group of animals that belong to the class Mammalia. They are known for their unique characteristics, including giving birth to live young ones and providing them with milk for nourishment. The word "mammal" comes from the Latin word "mamma," which means breast, highlighting their distinctive feature of mammary glands.

**Characteristics of Mammals:**

Mammals possess various characteristics that distinguish them from other animal groups. Some of these characteristics include:

1. **Warm-Blooded:** Mammals are warm-blooded, meaning their body temperature is regulated internally. This allows them to maintain a constant body temperature, regardless of the external environment.

2. **Hair or Fur:** Mammals have hair or fur covering their bodies, which helps in insulation and protection.

3. **Mammary Glands:** All female mammals possess mammary glands that produce milk to nourish their young ones.

4. **Internal Fertilization:** Mammals have internal fertilization, where the sperm fertilizes the egg inside the female's body.

5. **Viviparity:** Unlike other animals such as reptiles or amphibians that lay eggs, mammals give birth to live young ones. This is known as viviparity.

**Examples of Youngone Giving Mammals:**

1. **Humans:** Humans are a prime example of mammals that give birth to live young ones. The process of human reproduction involves internal fertilization and the development of the fetus inside the mother's womb.

2. **Dogs:** Dogs are another example of youngone giving mammals. Female dogs go through a gestation period and give birth to live puppies.

3. **Cats:** Cats also belong to the mammal category. They give birth to live kittens after a gestation period.

4. **Elephants:** Elephants are notable examples of youngone giving mammals. Female elephants have a long gestation period of around 22 months and give birth to live calves.

**In Conclusion:**

Mammals are a diverse group of animals that give birth to live young ones. They possess unique characteristics like being warm-blooded, having hair or fur, and possessing mammary glands. Examples of youngone giving mammals include humans, dogs, cats, and elephants.
