Thanks for sharing.
The way I see things, the kinds and the DNA would be one and the same, it being an aspect of the kinds’ physical manifestation. Kinds, being an organizational principle that brings together those that exist ontologically below them - atoms and cells.
All existence has a triune nature reflecting that of Existence itself. It is all about relationships - something interacting/connected to something it is not, existing as itself and/or one with what is other. That’s how we, how animals, plants, one-cell creatures, the atomic and the subatomic are and function. Atoms interact in accordance to the four basic forces and the constants found in nature. Those are the “instincts” built into that level of existence. Paramecia bump around, interacting with their watery environment, ingesting what are nutrients, avoiding dangers. Plants grow their roots in the ground and reach out to the sun, as they utilize the material of which they are a part, to develop from seeds and grow to make more of their own. Animals actively seek out food and a mate, protecting themselves and many, their offspring. And, we are here discussing issues as a function of our capacity to perceive, think and even better to know, feel and act, in a holy unity with the world and Existence itself, which because we bring everything back to ourselves rather than give it all back, we cannot experience but in the most rarified moments.
Living organisms, while existing as one in themselves and in relation to their environment, operate along three dimensions. It is clearest in us since it is what we are and we need only know ourselves. On the physical side, the cellular components, granted to them by the gametes donated by their parents, which include the DNA, but also everything that necessarily goes with it, are brought together under the “kind” that would be their soul that is the unifying principle that defines their individual existence and the sort of relationships they can form. Within the environment, as small as it might be in the womb, but stretching out to cover the earth and beyond, the physical aspect of the soul incorporates external matter, beginning with that of the sperm and ovum, to form the organism. At the same time, there exists a psychological dimension which determines the sorts of perceptions, feelings, and behaviours that creature will exhibit. A basic component of mankind’s "instinctual’ life is a free will and the capacity to know - to love in other words. Within the unity that is any living thing there is what is basic to all this, a spiritual dimension - the soul that is the particular being of the creature, bringing together in a unity, within its environment, its reality - as it is known by God, the Source of all that is everywhere and in every time.
I suppose the DNA and its supporting structure, since it is useless by itself, dictates what the particular individual organism will be like as an expression of its “kind”, the particular soul of the “species”, which is Adam and Christ in our case. The DNA, thought of as being more than just stuff, but as information, can vary greatly among us, but we are all one humanity.
