Why are reptiles so ugly?
<|assistant|>
Unlike animals that have adapted to live in a particular environment, reptiles have remained much the same over hundreds of millions of years – which likely explains why they can still be quite “ugly” by human standards. In addition, unlike other animals, the vast majority of reptile species do not produce their own body heat, so it makes sense that they have a less diverse range of external features and coloration to adapt to their environment than many other animals.
