Explain why the development of the amniote egg was so significant in the evolution of the reptiles. What will be an ideal response?
The amniote egg allowed the developing organism to bypass a larval stage that needed to live
in water. Therefore the land-dwelling organisms were able to inhabit many ecosystems on
land without being dependent on water for part of their reproductive cycle. The organism that
hatched was self-reliant and looked like a miniature adult; presumably the hatchlings were
able to take care of themselves immediately. This was a crucial adaptation at the end of the
Paleozoic; as Pangaea was being assembled, wetlands were disappearing and great stretches
of arid, desert-like regions were created.
