"DNA 'evolving' into another DNA cannot be observed because of the genetic drift"? I'm not sure what that is even supposed to mean. By "DNA" I am presuming you mean "DNA sequence". In this case, we have observed it: new DNA has been added to the sequence of bacteria and insects, in the forms of antibiotic and pesticide resistance. We've also observed new systems emerge in the form of nylonase.<quoted text>
You really don't see it? DNA is a part of the universe. The claim was that DNA "evolving" into another DNA cannot be observed because of the genetic drift. There was an argument that the change can be seen but it cannot be truly observed. Why not, because it just can not!
The claim didn't actually make any sense to me, but alas, there it was, presented to me. And I had to counter it, twice.
I'm also not sure you know what genetic drift actually is. Genetic drift is, according to Google Dictionary, "the change in the frequency of a gene variant (allele) in a population due to random sampling". In case you don't understand, let me explain it to you in the following scenario.
Imagine there is a population of creatures. These creatures can either be fast or slow, and can be either red or green. There are predators which can eat the slower creatures. The color of the creatures does not impact their survival, as there is nothing to blend in with. Since color is not selected for or against, it will simply be inherited from whoever survives. The fast creatures are mostly green, while the slow creatures are mostly red. As the fast creatures dominate the population, greenness also dominates. Being green was not favored for by natural selection, though, but was random. This is an example of genetic drift: the genes for being green became more common due to chance, and not due to helping organisms survive.
This still has nothing to do with the original question, which is if matter is ultimately consisted of tiny particles. The simple answer is "yes", although this is a question of particle physics and not evolutionary biology. Why it is here is not apparent.
