This was what Darwin faced when he set out to describe nature with the Theory of Evolution. Besides working with observations based on distorted images he needed a scenario or outline that would make sense of his observations. This is where he turned to Christian beliefs. In Christianity there is the idea that some survive and some become “extinct”. There is also the idea that changing one’s nature is the key to survival. This fit well with his observations and with a few adaptations became the Theory of Evolution.
This is completely speculative, and indeed, unlikely given Darwin's own words about Christianity. Most of Darwin's theories come directly from observation, however, since the study of heredity was primitive in those days, he did not have the words in which describe his observations as eloquently as we can now. He did form some lofty theories and hypotheses based on his observations, but to say that he used Christianity to expound upon them has no factual basis.
He makes no allusions to Christianity, whatsoever, and the supposed one's you give seems to be completely invented in your mind. Think about how easy it is to draw parallels, real or imagined, for just about anything, as Larni has already shared?
There are superficial parallels, but I could easily draw the same kind of parallels with Christianity to emergency medical technicians, that resuscitation is actually a metaphor for the resurrection of Jesus Christ. I mean, I could on all day inventing parallels from the most vague and superficial things.
“I know where I am and who I am. I'm on the brink of disillusionment, on the eve of bitter sweet. I'm perpetually one step away from either collapse or rebirth. I am exactly where I need to be. Either way I go towards rebirth, for a total collapse often brings a rebirth." -Andrew Jaramillo
