Lizards once ruled the earth as massive beasts, but over the course of time, evolution has changed them to be much smaller than they once were. While these creatures have been around for millions of years, they’ve had to change to become better suited for the environments that they currently inhabit.
The lizards that I am the most familiar with are now living in developed areas, such as rural neighborhoods and urban sprawls. While walking around my house or place of work, I often see the little green Anole lizards scurrying about. These little guys are small because they are naturally inclined to ...view middle of the document...
Because of that ability, they can get into many urban buildings to keep themselves warm when they need to be.
The urban environment is also useful for the lizards on the extremely hot days. Because of the nature of the urban environment, there is plenty of shade to help cool them down if they begin to overheat. Many buildings also offer air conditioning to help speed up the process. This again goes back to their ability to reach very small spaces that most creatures cannot reach.
The small lizards also have to worry about predators in the urban environment. Stray cats and dogs can find them. According to the page by Joanides (2011) lizards also have the ability to lose a significant portion of their tails under duress, a tool used to distract predators. After they have utilized that method while trying to escape predators, the lizards in the urban environment also have another advantage over their attackers: they can hide in the crevices found along buildings, in a small enough space that a cat or other predator cannot reach them. Because of this advantage, there are a high number of lizards found in my area.
As I mentioned earlier, the majority of lizards primarily eat insects. Because of their diet, the insect population where...
