How have studies of the lizard species Sceloporus helped scientists understand how natural selection has favored changes between oviparity and viviparity?

Oviparity is favored in high-altitude environments.

  

There appears to be a correlation between cold weather and the evolution of oviparity.

  

Viviparous lizard species appear to have evolved from oviparous species.

  

Because oviparity evolved independently in two different groups of lizards, it is thought to represent the ancestral condition.
