Do birds and reptiles fertilize eggs internally or externally?

Both birds and reptiles fertilize eggs internally. Both types of animals have an opening called a cloaca. This opening is where eggs, sperm, and bodily waste travels in the body. Male birds and reptiles will deliver sperm to the female’s cloaca.

How did reptiles evolve into mammals?

One branch led to later reptiles which evolved hard-shelled eggs, which evolved into birds, and the other branch of soft-shelled egg reptiles eventually evolved into mammals. The evolutionary literature never states exactly which reptile evolved into mammals, or what kind of egg shell it had, or any such detail.

Do birds have external or internal fertilization?
