Q. Why can the allantois be considered an adaptation to terrestrial life?

The allantois is an adaptation to dry land because in embryos of oviparous terrestrial beings like birds and reptiles, the metabolic residuals cannot be immediately excreted to the aquatic surrounds (as amphibian and fishes larvae do). It was essential then for the appearance of a structure capable of storing the embryonic excretes until hatching.
