The evolutionary innovation that allowed animals to move out of the water onto land successfully is the development of amniotic eggs.
<h3>What are amniotic eggs?</h3>
Amniotic eggs are eggs that contain amniotic fluids. The amniotic fluid in eggs primarily serves as a shock absorber and protects the embryo from desiccation - drying up as a result of heat.
One major challenge facing the movement of animals from water to land is desiccation. Being totally out of water predisposes animals to being dried up as a result of heat from the sun.
Particularly, solar heat acts as a threat to the young ones of animals on land. The eggs of animals in the water mean that the embryos are safe from desiccation.
Thus, the evolutionary development of the amniotic egg that is capable of withstanding the various limiting factors offered by the terrestrial environment.
The egg also remove the dependency on water for reproduction by animals.
