Question

Quizplus · Accepted Answer

Sexual selection and genetic drift both influence the genetic makeup of a population and can lead to the development of new traits and diversity in species. The other statements are false. A is false because different environments and ecological communities can lead to different adaptations and diversity of life. C is false because Earth is estimated to be around 4.5 billion years old and has undergone significant changes over that time. D is false because ancestral forms of life have evolved and diverged to become the wide range of species that exist today. E is false because while all life on Earth shares a common ancestor, there have been significant genetic divergences and differences between organisms over time.
