“Species” do exist, as we well know, but they are not static entities.
I exist, You exist. This computer exists. I suppose that species exit as do computers - a general term or category of things that actually do exist.
I think that there are in fact “kinds” of things, “souls” that makes them what they are in themselves, that do exist regardless of our categories. These are generally not congruent with our idea of species as we have defined them scientifically.
Let’s take ourselves as an example. A person exists. So does one humanity, as more than a collection of individuals, but rather as something real - the body of Christ, fallen in Adam, of which we are all individual manfestations, separated even within ourselves as a result of original sin, and made whole through Love.
So, as we have defined them, species represents an illusion. The reality behind them, however, that which we know and to which we give names such as bird and reptile, I believe does exist. It is not so much static, but rather ontologically fixed at the foundation of what the particluar thing is, be it an atom, a bacterium, a plant, animal, or human being. Organisms, we can say manifest themselves, or alternatively, are brought into physical existence individually, as expressions of the truth that is the particular soul or beingness of the creature, providing it with the attributes that make it what it is.
I was unable to communicate what I intended by the first question. It is quite precise and speciation does not come close to being any sort of answer because it is part of the question itself. It’s a bit unfair in that it is seemingly way above anyone’s pay grade. I tried to make it understandable by referring to a specific trait, that of sexual reproduction.
What “evolutionary” changes do you imagine as having happened in living organisms that brought about sexual reproduction?
By the way, I would suggest you not waste your time asking me to refer to Google in your responses. Should you wish to mention a source which backs up any of your claims, please provide the quote you would want me to consider and the link. I’m more interested in what you think anyway and I have an appreciation of the science and opinions that are out there. The aim here as in all of our daily lives, has to do with growing in faith. This topic provides insight into some of the pit-falls and obstacles in our search for the truth.
