What is the origin of a new species in evolution?

Answer 1

Speciation
Evolution is the gradual process in which already existing species undergoes in order to have a greater chance of survival. Because Natural Selection takes place, random mutations occur in offsprings, and so new characteristics and attributes are formed. These random mutations may occur because they may have a greater chance of survival or because it would benefit them in some way. For example, the giraffe's long neck came about when it found that it needed a way to obtain leaves from the tops of trees. And so, generation by generation, it's neck slowly lengthened until it was able to do so.

Answer 2

A new species can arise through a process called speciation, where a population becomes reproductively isolated from the parent population and evolves independently. This isolation can occur through geographic separation, genetic mutations, or other mechanisms that prevent mating between individuals of the two populations. Over time, these differences accumulate, leading to the formation of a new species.
