The other major group of reptile descendants, the birds, not only have continued the reptilian tradition, but have evolved eggs of an improved design in a wide variety of sizes, shapes, colors, and textures. Bird eggs are virtually self-contained life-support systems.
Why do birds lay eggs in drier environments than reptiles?
Birds can lay their eggs in even drier environments than reptiles, because when the fatty yolk is broken down to provide energy for the developing embryo, water is produced as a by-product. Reptile eggs primarily use protein as a source of energy and do not produce as much “metabolic water.”
