Probably survival of the species in perhaps a harsh environment. In cooler climates, where the temperature might fluctuate over a wide range, it makes more sense for the female snake to incubate the developing embryos inside her body. That way, she can regulate her own temperature. In hotter climates, its easier to deposit eggs under the earth where a constant temperature will incubate the eggs for her.
