I’m not sure how you are using the word “evolve”. We are not a species of animal, but a new creation. A poster above wrote about St Thomas’ idea about the nature of living souls. They are what define what something is. To my way of thinking, even atoms have a sort of material “soul” that makes them what they are, even though they are made of “light”.
Animals do not sin; they act on instincts. Their perceptions, feelings and reactions are built-in. They have sex to procreate, not knowing why, and they can get confused.
Persons on the other hand have a free will which governs how we behave in a moral context. But just as we have lungs and bones and livers and skin, breast feed our young and so on, we share some of their instinctual nature. We get angry, sad, sexy; we feel pleasure and pain. We can see and feel, taste and smell; we hear. But we do so, grounded in eternity and with the capacity to know beauty and goodness. Our free will makes it possible to love, to give of ourselves for the good of the other. A dog will remain loyal because that is its nature. To remain loyal in the face of known adversity, to follow any good when we know it runs counter to our own will, that is love. Animals have no choice; we do and it determines who we are.
If you look at life as a whole, it most definitely reflects God’s nature by virtue of its giving itself to itself. As it does so, it lives, grows, and propagates in all its diversity. We don’t like being part of that, although intellectually we can accept that we will end up as food for worms. Nature is amazing!!
I don’t think I’ve connected with what your issues are, but that’s how I see it.
