This is my first post. If I could ask Professor Dawkins a question today, it would be, “What is it about the molecular logic of living systems that results in no species ever evolving more than once?”

I’m not Dawkins, but I’m sure he would ask you where you got that idea? Whoever posited that notion does not know anything about evolution.
We can begin with the definition of evolution and then follow that up if that is not clear enough.
Evolution is change in the heritable characteristics of biological populations over successive generations. ... It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.https://en.wikipedia.org/wiki/Evolution
Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. ... Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.https://www.nature.com/scitable/knowledge/library/speciation-the-origin-of-new-species-26230527/
What are the 4 types of speciation?
There are four major variants of speciation: allopatric, peripatric, parapatric, and sympatric. Speciation is how a new kind of plant or animal species is created. Jan 21, 2011https://www.nationalgeographic.org/encyclopedia/speciation/
