Why are reptiles so ugly?
<|assistant|>
Reptiles evolved as their skin hardened over time, and this process left them with an appearance that is often uneven, bumpy, or lumpy. This means they have a lot of surface areas that can be difficult for them to keep warm, so their external features evolved to be able to better tolerate the heat. Additionally, since many reptiles lay eggs, their bodies have become adapted to ensure that the eggs hatch even if their appearance is less than perfect.
