They call it macro-evolution, but trans-specieal highlights that more than one supporting belief is needed to arrive at the conclusion that it is possible.
Well, macro-evolution or trans-speciation, most people have no idea what they are talking about when it comes to these concepts. They have been sold a line that there is a huge distinction between evolution within a species (which leads to species changing form over time) and evolution of new species. This is often misrepresented as "one species changing into another" which is not a good description of what really takes place at all. They have been told that evolution within a species is no big deal but macro-evolution is not possible.
Well that is blatantly false. Macro-evolution--the emergence of new species--is not at all impossible; it is an observed fact. There are all kinds of verbal tricks used to get around this and it is certainly the aspect of evolution about which there is the most confusion and obfuscation.
Almost everyone who thinks macro-evolution, or trans-speciation if you prefer, is an impossibility really has to unlearn a lot of things they think they know before they can get a grip on what macro-evolution really is (it is NOT a leap from one species to another, especially in a single generation) and learn how it actually happens.
I wonder how much you have to unlearn before you can begin to learn?
Oranges are oranges and apples are apples. If it is trees budding from trees, then at some point it is leaping from one rung to another rung.
No, there is no leaping, not from rung to rung, nor from branch to branch either. There is growth, there is change, there is dividing into sub-populations (sub-branches), there is a proliferation of new twigs and leaves from each branch, there is modification, adaptation, diversification, but no leaping any sort of gap.
And here is where you throw the baby out with the bathwater. How pray tell does Evolution happen if desire or will power are not present?
As God arranged it to, through the physical forces and properties God put into play. In terms of mutations, they are changes in the structure of the DNA molecule. Atoms are rearranged to produce a different pattern of base nucleotides. When did you or any organism or any collective of organisms produce such rearrangements because you wished to or willed to. What effect does your will have on the sub-atomic particles of molecules in your cells?
As I said, I can see a place for God's will to impact such events, but not mine.
Besides, evolution has been going on long before anyone knew there was a DNA molecule, even before they knew there were molecules or atoms. So what role could human or animal or vegetative will play when these species were/are totally unaware of the possibility of evolution or the basis of genetic changes?
Some parts of a very large molecule get rearranged, and in some cases this triggers a different chemical reaction. Chemical reactions are taking place in all your cells at all times in a bewildering number and variety. Are you aware of them? Can you choose what chemical reactions occur via your will, your desire? Not directly, that's for sure.
(One can have certain impacts on one's body chemistry through life-style choices about what to eat, how much exercise one gets, and so forth--but this is more indirect.)
Such changes are taking place in every cell in your body, every time a cell divides. But the only ones of importance for evolution are those that occur in germ cells.
Do you consciously will the production of sperm? Does your desire or will-power impact the quality and character of your sperm cells? Is it your will or desire that specifies which changes, if any, from your parents' genomes will appear in the newly-generated sperm cells? And is it you or God who chooses which of several million sperm will fertilize an egg in your partner's body?
For the newly-conceived organism, the process of development and maturation takes over from this point on. But all this is merely the preliminary stage-setting for evolution of the species.
Who wills or desires the dance of population genetics? Of selection pressures? Of dividing populations? Certainly not individual organisms.
So the only entity whose will or desire I can see being expressed through evolution is that of the Creator and Sustainor of life. This is something God takes care of. Not us, not any species, for we have no capacity, as yet, to direct our own evolution. We do direct some of the evolution of other species via selective breeding and now genetic engineering, but this cannot be the way evolution has happened in most of history.
And if those things are loaded with information that influences the genetic determination of the organism?
It doesn't matter how much information there is in one's emotions or thoughts if they cannot cause molecular changes or chemical reactions or impact the distribution of chromosomes in meiotic cell division or determine which sperm fertilizes which egg, or set the ecological conditions under which an organism will live and the challenges it will face.
As I see it, the only Being of which it may be true that thought, desire and will can influence all these things is God.
Potentiation means that the children avoid the same pitfalls with the same genetic material, or that they change the genetic material altogether. It is not necessary for the person with ALS to die, as Evolutionists put it. The ongoing communication with the person before they die, not only ensures that the problem DNA is dealt with, but that all contributing factors are thoroughly considered also.
Yet they do die. And if some of their children have inherited the gene, they also succumb to the illness and die. The one way to remove the legacy from the family is for those with the gene not to reproduce unless they are sure the embryo has not inherited the gene.
How do you think the problem DNA is dealt with? The gene doesn't simply disappear from the cells of a person who inherited it.
Except that a law follows cause and effect, not probable cause and unknown effect.
We live in a quantum world; all causes are probable. And as for natural selection, we know what the effects are.
I mean, what about the fact that unless you fix your efforts at adaptation on a single point, across multiple generations, you will never truly adapt the best examples of a given species possibilities?
True. This is why you seldom see much evolutionary change in large, stable populations with a significant geographical range. It takes much time for an evolutionary change to spread through this kind of population and before an adaptation has much impact, the selection pressures have changed to favour a different adaptation. This was observed on a small scale when Peter and Rosemary Grant studied the finches of the Galapagos through a severe drought followed a few years later by abundant rain. Under drought conditions, there was a push toward larger body size and larger, stronger beaks. Under rainy conditions, this was relaxed and smaller birds with smaller beaks became more numerous again. Over geological time, this would get averaged out.
This is also why the most dramatic examples of evolutionary change occur on the periphery of habitat zones, in small relatively isolated pockets of the population. An adaptation can spread more quickly through the small population, and there are often special conditions that favour a change that endure long enough for the adaptation to take hold.
So you are right--there does need to be sustained "focus" that moves a species in a particular direction over generations to realize an adaptation.
You don't think speciealized adapation is going to "outlive" random mutation by a severe degree? I really don't see how you can argue that, it is on your terms, after all.
Oh absolutely. That is why I keep telling you that evolution is not an accident. It is not a matter of chance. In the long term, it is selection that outlives random mutation and really sets the ground rules of evolution.
It is notable that virtually all evolution-denying literature downplays the crucial role of selection while focusing on the randomness of mutational events. That is why people get confused into thinking that evolution is all a matter of chance and accident.
But evolution actually has rules and patterns that are understandable if one takes the time to learn them.
