Question

biologists is studying two species of lizards in a mountainous region. The two species are separated by habitat with one species occupying the protected valleys where the other is exposed to high elevation mountain range where conditions are unpredictable. She finds that one species is oviparous and the other ovoviviparous. Which species would you predict would be oviparous and which ovoviviparous and why

Answer 1

Answer:

Valley lizard = Oviparous

Mountain lizard = Viviparous

Explanation:

In Darwin's theory survival of the fittest, he believed species adapt or change within their environment. So I believe lizards living in a valley would be more safe to lay their eggs but lizards living in the mountains would be viviparous because of the non-predicted and unsafe environment which could harm the better chances of development of the offspring.

Answer 2

Answer:

The specie in protected valleys will have ovoviviparous population.

The specie in unprotected environment will have only viviparous population.

Explanation:

viviparous has larger proportion to survive because it have larger hatching success because of favourable environment.
