When an oviparous animal lays eggs their choice is to
stay with the nest at all times and go without eating, leave the nest to eat leaving the eggs unprotected, have a mate that shares the responsibilities of
protecting and nurturing the eggs, doing nothing and leaving...etc. Even with all these possible protections the results can be lost eggs or an injured or dead adult. The less care that is taken, the more eggs must be laid in an attempt to
have a few survive to adulthood.
Think of the advantage of carrying offspring on the move...by protecting itself the parent protects it's offspring...a much easier task.
More complex animals, that have fewer offspring that require more nurturing and training after birth are at an advantage by being viviparous as more development can take place before birth.
well over time the land animals change a little and they need to be underwater to live unlike their land animal ancestors
