Question

Extraembryonic membranes, such as the amnion and allantois, provide a protective environment for the egg and allow for gas exchange without the need for water. This adaptation has allowed chickens to lay their eggs in drier environments rather than needing to lay them in water to maintain proper conditions for development. The yolk, cleavage, gastrulation, and development of the brain from ectoderm are important processes in embryo development but are not directly related to the adaptation to laying eggs in arid environments.
