Question

Which of the following is a possible scenario that could lead to a new species? A tree frog needs to jump higher to escape predators. The frog's offspring jump higher due to the frequency of jumping by the parent. Over time, many mutations occur in the gene pool of a population of butterflies. A giraffe stretches its neck to reach the leaves at the top of the tree. The offspring are born with necks that are longer than the parents due to the stretching. A bird and a frog reproduce with one another, creating a "brog."

Answer 1

Over time, many mutations occur in the gene pool of a population of butterflies. 

Answer 2

Answer:

The correct answer would be "Over time, many mutations occur in the gene pool of a population of butterflies".  

Speciation is a natural process by which new and distinct species is formed during the course of evolution.

Accumulation of mutations or genetic variations over several generations leads to the change in the genetic make-up of the population which leads to the formation of new species.

Similarly, several mutations in the gene pool of the butterfly population can lead to the formation of new species.
