One adaptation was hard-shelled eggs that were impervious to water loss. This allowed the embryo to survive without the egg having to be laid in water.

It's possible that early reptiles did not, but modern reptiles certainly do.

Agriculture. More food allowed specialisation, cities and settled government.
Early Americans were isolated from the rest of the world due to geographical barriers like oceans and mountains, which limited contact with other societies. This isolation allowed them to develop in ways similar to other early humans through independent innovations and adaptations to their environment. They faced similar challenges such as securing food, building shelter, and establishing social structures, leading to comparable strategies and solutions.
The amniotic egg allowed early reptiles to move away from waterside habitats and colonize dry regions. It allowed reproduction on land by preventing the embryo from drying out, so eggs could be laid away from the water.
Humans evolved quickly compared to other species due to a combination of factors such as bipedalism, increased brain size, tool use, and social cooperation. These adaptations allowed early humans to efficiently adapt to changing environments, develop complex societies, and outcompete other species.
Most scientists believe that reptiles evolved from amphibians, specifically from ancient creatures known as early reptiliomorphs. These early tetrapods adapted to a more terrestrial lifestyle, eventually giving rise to reptiles.
