Red-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatching. Explain your answer in 1–2 sentences.

Hatching is an essential embryo behavior that mediates the transition between two distinct stages of life, in the egg and post-hatching environments, when developing animals are exposed to different risks and opportunities. Variation in either of these environments can affect when is the best time to hatch. Environmentally cued hatching allows embryos to respond adaptively to their local environment by altering the timing of their hatching. Therefore, the vibrations can make the frog eggs hatch before time. So if it hatches more then two days early the frog will not be able to live and will die.
