Example of Natural Selection

The History

Lizards are cold blooded rep tiles. They can not make their own body heat so they spend most of their time in the sun. There are more than 3,000 species of lizards making them the largest group of reptiles. They have dry, scaly skin and clawed feet.

How Lizards Became an Example of Natural Selection

Natural selection of these lizards by predation did not produce new traits or variations, it diminished them.

Necessities for Natural Selection

The first is reproduction, then competition, after that comes survival of the fittest environment, and lastly the genetic variation.

The Future of Lizards

The extinction of lizards is possibility in the near future. This is mostly because of climate change. The University of Lincoln has done some major studies on this topic.
