Does the feeding difference in wasps indicate evolution?

The Details of the Question

Claim: “Scientists have documented three species of wasps turning into three new species, an unusual close-up view of rapid evolution in action. In a study published in the Proceedings of the National Academy of Sciences, the team found that evolutionary changes in one species of fruit fly triggered a cascade of evolutionary changes in three species of wasps that are predators of the fruit fly. For thousands of years, the native North American fruit fly Rhagoletis pomonella fed on the fruit of hawthorn trees. Then, in the 1850s, researchers discovered that the fly had jumped to the apple tree, which is a related plant. Rhagoletis had split into two species. Those that lived among hawthorn trees, for example, emerged at different times than those that lived off the fruit of the apple. Rhagoletis is preyed on by three species of wasps. The flies’ larvae live inside the fruit. The wasps lay their eggs inside the larvae. The flies hatch. Later, the wasps hatch, too, devouring their host fly from the inside out. What Dr. Egan and his team discovered was that the speciation that originally occurred in the fruit fly also triggered a speciation in each of the predator wasps. In the PNAS study, they document how hawthorn-living wasps have different life cycles than apple-living wasps. The genetic makeup changed, too. In addition, differences in behavior indicated that physiological changes had occurred as well.
Thus, three species of wasps became six. In nature, at least, they never would meet and breed.”

The Answer

Dear Brother / Sister,

What is meant in this question is the claim that some speciation was observed among wasps arising from feeding differences.

First of all, the feeding difference of bees is not a new phenomenon. In other words, it is not something observed by preparing a new food medium in the laboratory.

It was previously thought that the feeding of wasps was based only on the fruit fly that fed on hawthorn trees. It was understood in the 1850s that bees also preferred fruit flies that fed on apple trees. In other words, it is understood that the wasps observed among the wasps and expressed as six species existed in the past too.

Even if all this is not taken into consideration, intra-species differentiations are always possible because not all members of a species are the same as if they were photocopied.

Every individual has a number of different characteristics and structure differences. Therefore, the sum of the characters of the members of a species is called a gene pool.

As a result of the mating of individuals in this gene pool, it is possible for new structures and characteristics to emerge as a result of the combination of differences each individual takes from their parents. However, these variations do not display a change that is enough to go beyond that basic type.

For instance, a child's eye color consists of a combination of the eye color characteristics that his mother and father have. The eye color of his mother and father is a combination of the characteristics of all of his ancestors beginning from Hz. Adam.

It is necessary to view the issue like that.

It is not scientific to make a generalization that there are transitions between large groups and basic units acting upon intra-species variations.

Each large group of living beings was created separately because the genetic structure does not show a big change to bring about different groups as it is claimed.

For instance, there are variety differences among the types of corns such as flint corn, sweet corn and starch corn. New varieties or types are expected when they are crossed over or crossbred. It is no evidence for evolution in the sense of the claimed evolution. That is, it is not scientific to claim that large, basic, different genetic types such as beans from corn, wheat from beans and potatoes from wheat occurred with these changes.

Likewise, the differences that occur due to some feeding differences among the wasps keep them within the borders of wasps. For instance, 6 species that are known today in the basic bee type of wasps may just as well be 16 species for a number of reasons. However, all of them are within the basic type of wasp.

In other words, it is not possible for another basic type like a bird to occur through the evolution of wasps.
