A lizard is a reptile for several reasons. It is cold-blooded, unlike mammals which are warm-blooded. Also, it lays eggs, whereas mammals do not, and it also does not have hair, which mammals do.
A bird, reptile, fish, amphibian, or invertebrate. Some mammals come from eggs too.
In reptiles, fertilization usually takes place internally inside the female's body. Male reptiles deposit sperm inside the female through cloacal contact during copulation. The sperm then fertilizes the eggs within the female's reproductive tract.
Actually, not all animals that lay eggs are mammals, and not all mammals give live birth. Some snakes have livebirth(reptile), and the platapus(mammal), lays eggs. But, to answer your question, animal that lay eggs are called reptiles, amphibeans, fish, and birds.

No, a reptile has the ability to lay eggs. Mammals give birth to their young after a period of time, as the egg develops inside them, to first become an embryo, and then a foetus.
all animals have eggs, but it depends their fertilization development type (which is either internal or external). Humans are mammals, and all mammals give live birth unless it is a monotreme, which lays eggs.
