Why is our body temp. 98.6 or why do we get fevers? 98.6 is because that's the way we have evolved. Birds are 102. That works for them. If we didn't have a steady temperature, we would be cold blooded like snakes and lizards.
Fevers? A fever is usually a response to an infection. The body working to get rid of the infection and the poisons from the infection can mess with the body ability to regulate the temperature.
As temperatures rise, the body temperatures of heterotherms also rise. This is in contrast to homeotherms, who have a constant body temperature.
Body temperatures vary, even within humans. The body temperatures of mammals range from around 97° to over 103° Fahrenheit. Birds have average temperatures of around 105° Fahrenheit.

Some animals have bodies that can control their own body temperatures. Some animals have to find shade or water to control their body temperature.
