- (Breana Brock P: 3) 1:Population
- 2: Genetic Variation
- 2: Overproduction of Offspring
- Lizards are very populated in the Syrian Desert. Their predators are different types of birds. The different color skin of the lizards show the population variation. The color of their environment determines their survival by natural selection.
- 4: Competition & Natural Selection
- Genetic variation gives all the lizards notably different characteristics. The main one is their skin color, some are dark red, some are light blue and others are green. Genetic variation is the genes creating different individuals in the same population.
- 5: Adaptation
- From the start of the hot summer season, many new baby lizards are born in various amounts of colors. However it's alarming how many new lizards are born aka, overpopulation. Shelter, safety and especially food will become scarce.
- Evolution Has Occured
- The dark red and light blue lizards are easier for its predator, the hawk, to hunt. The lizards with the green skin can hide easier and the green lizards can almost camouflage in the desert. It's natural selection where the best suited for the desert environment will survive and reproduce comfortably.
- Green skin lizards were more likely to survive and create more offspring than any other. After various years of natural selection, this left most of the population of the new generation to be green lizards. The offspring now carry the heritable trait of green skin ,making it easier to adapt and survive in their environment.
- Evolution can happen quickly or slowly in an environment depending on the size of change and genetics in population. The genetic differences can include a short/long tail, light/dark skin, short/long back legs etc. In this environment specifically, the dominant genetic trait is green skin. The environment of the desert gives a sort of layout to whom can adapt , survive and create offspring.
