Just because they are two different concepts does not mean they are unrelated. I am frankly alarmed at the suggestion one can have abiogenesis without evolution. How can this be? Granted, abiogenesis may be one particular focus of certain scientists, but I cannot understand how they could possibly divorce one from the other en toto. I can certainly understand why one would want to turn a blind eye to abiogenesis while arguing for a universal history of simple to complex biological forms.
seriously...alarmed??
I understand your intuition about these two disciplines---they should be related, you feel.
There are many obstacles to that happening. To mention a few, I think, is sufficient.
Where does, in historical perspective, abiogenis begin? Before the Big Bang? After? etc.
That takes us immediately back to the Big Bang, and events before which we must forever remain ignorant. We'd be getting close to the supernatural, and science abhors the unempirical.
Outside the MSM, the Theory of Evolution, and its proponents, has never been about the beginning of life. I think that is the result of the first issue I raised. Also scientists tend not to venture beyond the limitations of the scientific method.
Some scientists, on the other hand, do research in abiogenesis. Most are in the Chemetistry areas of research. Today, bringing the Chemical research into the fold of those searching for the beginning of life is unwarranted simply because the data are not sufficiently supportive.
