Briefly state why the development of the amniote egg was so significant in the evolution of the
reptiles. What will be an ideal response?
Amphibians were limited in colonizing land because they had to return to water to lay their gelatinous
eggs. Reptiles developed amniote eggs in which the developing embryo is surrounded by a liquidfilled
sac and provided with food and a waste sac. This egg allowed reptiles to colonize all parts of the
land.
