Final answer:
Yes, the information of a new species can come from an existing species and can occur in two phases: allopatric speciation and sympatric speciation.
Step-by-step explanation:
Yes, the information of a new species can come from an existing species and can occur in two phases. This can happen through the process of speciation, where a new species evolves from an existing one. Speciation can occur in two main ways: allopatric speciation and sympatric speciation.
In allopatric speciation, geographic barriers separate populations of the same species, leading to the accumulation of genetic differences over time. Eventually, the two populations become reproductively isolated and form distinct species. Sympatric speciation, on the other hand, occurs when new species arise within the same geographic area, often due to ecological or behavioral factors that cause reproductive isolation.
For example, if a population of birds with a specific genetic trait were separated by a mountain range, over time, the populations on either side of the range may accumulate different genetic variations that lead to the formation of distinct species. Additionally, within a population, individuals with certain traits may occupy different ecological niches and develop reproductive barriers, resulting in the emergence of new species.
