Darwin didn't deal with the problem of the origin of life,

Darwin's goal was to explain how one species could evolve into another. That particular problem does require starting with a species to explain how it changes. He never addressed origins as that wasn't the problem he was trying to solve.

Never the less. Current biologist do include the beginnings of life in their studies.

Life today is pretty complex. It used to be simpler. Earlier than that it was simpler still. When it was much simpler then it took longer for a beneficial change to be expressed. For the first 3 1/2 billion years life never evolved past a single cell stage.

When you wind back to the absolute beginning then there is nothing to select, so there is no natural selection. The road to the 1st species would have been haphazard, but not completely random since the makeup of the earth is not uniform and random. Somewhere, perhaps near an undersea geothermal vent, there would have been energy and a chemical mix and some some chemicals would have come together to form a molecule that attracts the swirling chemicals to come together in the same pattern as the original molecule. Basically, life would begun with reproduction with selection happening much much slower for a long time.
