Hi and I could only agree but perhaps, I misunderstand what DNA is? I don't know that much about plant biology, etc., but it seems that it's much more deeper then DNA, alone; if we look at ourselves we see that all humans have a common DNA type that differs from a cat or dog, or any mammal. Within each 'species' of creature are a certain DNA type and though they differ from us they are unique creatures. Now, we must consider individualism in each one of the species and this is where the DNA plays a more detailed part in this factor, just like a snowflake is created randomly and each one is different, although they are all snowflakes.
Actually, humans (and other creatures) share much of their DNA with other species. As you would expect when considering evolutionary relationships. If you think about it, we share many characteristics with other creatures, so why not have the same DNA for those shared characteristics.
1. We are animals. For any feature common to all animals (as distinct from plants or fungi or unicellular life) we have DNA which is like that of other animals. So we have DNA that makes animal cells not plant cells.
2. We are bilateral animals. If we lie in a prone position on the ground, you can see that our basic body plan is the same as that of the simplest bilateral worm: mouth at one end, anus at the other, a backside and a stomachside (dorsal and ventral). There are a series of genes called HOX genes that controls the orientation and development of this body plan and they exist in pretty well every animal from snails to ants to giraffes to us.
3. We are chordates and vertebrates. That means our main nerve lies along our dorsal side, not our ventral side. We also have the genes for a tail that protrudes beyond our anal opening (though, like some other animals we lose the tail partway through our embryological development), we have a bony cranium encasing our brain and bony vertebrae protecting our spinal cord. We share all those genes with everything that has a bony skeleton.
4. We are mammals. We share with other mammals the genes which control body temperature, grow hair, produce milk and set our legs under us (rather than sprawling out to the side) when we put ourselves in a hands and knees on the floor position. We further share with them our three-boned inner ear, our single-boned jaw and our differentiated teeth. And with all placental mammals we share the genes that allow for intra-uterine development of our young.
5. We are primates. We share with other primates the genes for forward, binocular vision, a reduction in the number and variety of functioning olfactory genes, nails replacing claws at the ends of our digits, grasping fingers and in some cases, opposable thumbs. Also with most primates originating outside of the Americas, we share the genes for narrow noses with downward pointing nostrils.
6. We do have some unique features. Our erect bi-pedal stance, our feet made for walking not grasping, our chin, our flattened face, our large brains. For such unique features we have unique genes---but not genes without a pre-human history. None of these features appear de novo, but as modifications of features in earlier primates. And so the genes which produce them are not precisely new genes, but renovated genes whose counterparts we can find in our closest animal relatives.
7. Each one of us is unique, but again, not so much because we have different genes, but because genes come in many different variations which combine in many different interactions.
I used to have a small garden and I experimented with grafting; and then there are other plants like vines that can be cloned by clippings but the thing that I learned is that there's a difference on how the plant will reproduce fruits from either seed or cloning/grafting methods. A seed will produce an individual plant with it's own DNA, and perhaps I am missing much on these details, and then a clipping that is planted into soil with the rooting-hormone will sprout it's own roots and be a clone of the mother plant or tree, and yet they are physically individual's.
This causes me to recall the seed of Abraham, and all lineage in the seed; each seed would produce an individual character in each of God's children so that each is an independent person.
My experience was that the cloned plant produced the identical fruit as the mother and the seeded plant or tree produced fruits that slightly differed, although they might be all apple trees in the experiment. I saw this chronicled on a TV documentary on apples and other fruits in certain regions. They said that each apple seed produces a tree that produces a slightly different apple if the seed is not genetically modified. They have GM'd their seeds so to produce more consistent apples in the orchards with simpler seeding methods.
The reason a cloned plant produces fruit identical to that of its parent is that it gets all of its DNA from only one parent, and without the possibility of it being modified in any significant way.
Seeds get DNA from two parents, the plant that produces the seed (housing the egg) and the plant that produces the pollen (housing the sperm) to fertilize it. The production of both egg and sperm is a complex dance of chromosomes designed to produce a different genetic makeup than that of the parent, and then the fusion of egg and sperm generates an individual that is genetically unique. It is, indeed a complex system. It certainly ensures biodiversity. It seems that in this case the genetic engineers are trying to put brakes on that system.
Oh ya, I can't forget to mention that I believe in intelligent design and a creator of all things that are not man made.
That is why I accept evolution. It is a wonderfully beautiful system designed to naturally/divinely produce biodiversity. And I am grateful to the divine wisdom that designed it.
