Natural selection favors red-eyed tree frogs that hatch their eggs within the optimal timeframe, as those that hatch more than two days early are less likely to survive due to underdevelopment. As a result, embryos that can detect and respond to environmental vibrations, ensuring they hatch at the appropriate time, have a higher chance of survival and thus pass on their genes, reinforcing this timing trait in the population.
Red-eyed tree frog eggs can hatch up to two days earlier than average if they experience vibrations in their environment. If they hatch more than two days earlier, the embryos are not developed enough to survive outside of the egg. In 1–2 sentences, explain how natural selection keeps frog eggs from hatching earlier than two days before expected hatching.(2 points)
