Solution
The correct answer is "on land." The amniotic egg was a significant evolutionary development that allowed for embryonic development to occur on land. This is because the amniotic egg provides a protective environment in which the embryo can develop outside of water. The egg contains amniotic fluid which cushions the embryo and a shell which protects it from the external environment. This allowed species to reproduce away from water, which was a major step in the colonization of land.
