I remember a really great explanation in an old Biology textbook, but I no longer have it and I'm having trouble finding a good answer for you online. One big advantage is that because the offspring are carried inside the mother and not in eggs, they are mobile and the mother can protect them from predators.
Because internal developement decreases risk of environmental and predator harm; whereas external fertilisation increases these risks due to immediate exposure to such risks. Internal fertilisation also increases parental care due to less organisms being produced, thus increases the offsprings chance of survival
The advantage of internal development compared to the external development is that the local citizens get empowered. When there is internal development citizens in a particular country directly benefit.
External is outside the body and Internal is inside the body!
a adventage for internal development is parental care for the developing embryo
Internal development and external development? Please rephrase your question.
