For a scientist with a supernatural worldview, speciation might be expected, because they might believe the Creator only took a ​limited number of each species on the Ark and built into their DNA the genetic information needed to enlarge that population group over time. To them, they just see this as evidence for design and purpose.

For a scientist with a strictly naturalistic worldview, they often view any kind of change as microevolution in progress. To them, this proves evolution is observable.

What we believe about those type of changes is not the same as what we know about those changes. We each interpret speciation from our individual philosophical perspective.

What Do We Know About Speciation?

Speciation is how a new kind of plant or animal species is created. Speciation might sometimes occur when a group within a species separates from other members of its species and develops its own unique characteristics.

Scientists usually define a species as populations that can interbreed and produce fertile offspring. One species becoming two distinct species is called speciation. However, sometimes two slightly different species can still interbreed, but are considered different enough for them to be considered a different species. For example, the 13 or 14 different species of finch on the Galapagos Islands.

Several years ago, I spoke with a family of dog breeders who bred and sold a very unique breed of Scottish terrier. After a number of generations, a litter of puppies had some deformities. To correct this problem, they had to purchase a Scottish terrier from another part of the world, which did not have the same mutational loss of genetic information in their DNA.

From a scientific perspective, we know speciation takes place. There are worldview interpretations as to why it takes place, and to what extent. But we need to set those aside and just focus on what we know.
