One theory, the parental care hypothesis, suggests that there is an advantage to producing extra heat during reproduction, because the heat speeds up the process and provides the energy for a more attentive style of parenting.
Tattersall believes that the tegu may represent such a transition state from cold- to warm-bloodedness. But Tom Kemp, emeritus research fellow at the University of Oxford, says that warm-bloodedness is such a complex phenomenon that it is too simplistic to think that any one feature or adaptive purpose is alone responsible for its evolution.

It basks on rocks and the edges of roads. If threatened, the lizard defends itself by opening its mouth and hissing loudly. A pet with a lower metabolism needs fewer calories to continue its daily function.
POTR will also affect their immune system. Studies have shown that maximum immune response occurs when reptiles are within their POTR. In other words, they are better at fighting infection.
Just as temperature affects their metabolism, it also affects their activity level, so if a reptile seems lethargic, it could often be because it lacks the appropriate heat source.
A good rule of thumb for most species is to maintain a hot spot in the enclosure near the upper end of the POTR — generally in the upper 80 to 90 degrees Fahrenheit for most species. We recommend avoiding hot rocks or other heat sources that the pet can touch, as they can lead to dermal burns.
Another misconception is that reptiles only need heat during the day. Often, the POTR for the evening is only five to 10 degrees cooler than their day temperature, which would put it at approximately 70 to 80 degrees.
Humidity and water regulation have different meanings for various species. Maintaining the correct humidity levels can be challenging. An aquarium can work well for some reptiles. Remember, an aquarium has a tall and narrow shape, not allowing much airflow. If your reptile requires misting or likes to climb vertically, an aquarium is not the best option.
You might also create a humidity hide box — you can make one out of plastic with moist moss, like sphagnum, and a small opening cut into the lid. Stagnant air can lead to fungi and bacterial growth, causing infection. Some species, such as chameleons, can benefit from a vaporizer or humidifier used directly or indirectly with the enclosure.
A hygrometer is a necessity for any reptile habitat. Another essential factor in keeping a captive reptile is the substrate you use. A substrate is a material used at the bottom and within the enclosure. Some examples of appropriate substrates are shredded newspaper, cypress wood chips, stones that are too large for your reptile to eat and shredded coconut shells.
Many of these substrates can also help achieve appropriate humidity levels. Ensure your pet is not eating the substrate, as this could lead to a blockage. For many, this has just scratched the surface of reptile husbandry and care, but starting with the fundamentals of reptile housing is essential to keeping them happy and healthy.
Many of the problems and illnesses we see with reptiles are due to poor or inadequate husbandry or diet.
