I said there is no such thing as "species" at all
Not in any recent post in our conversation you didn't. You are adding new claims previously not in evidence.
and you say I believe an individual can change his species.
You said it, you just don't seem have the knowledge, experience and understanding of the material to realize you said it. I explained it. You did your usual and ignored it.
Obviously you are deconstructing my sentences in your terms rather than mine.
Obviously, you are trying to blame the lack of any supporting argument, evidence and understanding of the material onto me. It is not my fault or that of anyone else but yourself for the closed-minded and all seeing nature of your responses that have basis in fact that anyone, including you, has ever been able or, as the evidence indicates from your posts, willing to respond.
This works OK to maintain your existing beliefs but it is the root cause of our inability to communicate.
It would be impossible and logically inconsistent to believe every individual is the same species as its parents, no matter how you define "species" and then say that species change. Yes! I heard you say that Darwin believed a "species" is defined as all of its incarnations but these can not each manifest simultaneously and no evidence shows that the morphing over time resulted from survival of the fittest.
It is incorrect, logically inconsistent and outside of observation and experiment to claim that offspring and siblings are not the same species. You offer no evidence to the contrary and no reason to think this is more than an idea you came up with an fell in love with for not knowing any better.
Yes, you might object that each manifestation still exists within its genome but, again, most of the definitional and evidential problems remain. These older versions of the species were still each conscious individuals whether they reproduced or not. They are still distinct from the existing "species' and the path to the existing species was still a random walk that has not been shown to be based on some abstraction like "fitness".
That is all the evidence shows is that natural selection drives changes in populations. The changes aren't sudden across the population. Another thing you dreamed up and turned into a revealed truth without benefit of evidence or experiment. You've been routinely provided with references to experiments that demonstrate natural selection acting on fitness within a population. You just ignore and repeat your slogans.
There remains the logical inconsistency that if the species Evolved according to "fitness" then each generation must be fitter than the last.
There is no logical reason to assume that and the evidence doesn't demonstrate that. It could be in some species with heavy selection, but once the selection relaxes, populations can stabilize over generations.
I can parse your sentences accordingly.
That seems like you are just saying you can ignore what I have taught you and substitute what amounts to your science fan fiction in place of that knowledge. You aren't parsing my words. You are ignoring them.
You can't step into the same river twice.
You like to deliver these slogans that must mean something to you, but nothing to me in the context of this conversation.
This is reality not some philosophical precept.
In my opinion, that is all you have and you created this personal philosophy for secret reasons and without benefit of a background in science, or knowledge of the subjects you make wild claims about.
For every practical purpose every individual is a different species than its parents or siblings.
Not at all. The evidence doesn't say and there is no valid reason to think it, consider it or use for anything.
I have a virtually "identical" twin who's two years older.
Good for you. You are the same species. Just different individuals. The similarities arise from similarity of genotype.
The fixation on what individuals have in common is what led to Darwin.
You call it fixation. Science calls it recognition of the evidence. Give it a whirl. Maybe you will learn something.
Individuals are an amalgam of their parents
Individual get their genes from their parents.
and hence are much more different than the rest of their "species' and more like their siblings.
They are the same species as their parents. Trivial morphological similarity or even differences don't make them different species. You are confused and don't have the knowledge bases to examine your ideas to recognize the glaring flaws in your mandates.
No doubt when bottlenecks appear most individuals have a far higher probability of being more closely related to other survivors.
Possibly. It would depend on the how they are dispersed through the environment, the nature of bottleneck event and the geographical manifestation. It does not have to be an event that leaves one population alone while eliminating others.
When the tamest wolves were selected to breed dogs
According to the evidence this selection took place on canines that were already becoming adapted to human contact.
each selected individual was more likely to be closely or distantly related to those selected than those which were not.
I have no idea what you mean. Those that were selected were likely already on their way down a path encouraged by the environment. Do you even know anything about domestication. It isn't just teaching Rover to roll over. There are a number of events that have taken place with some similarity of pattern across the various species of animals that have been domesticated.
If you must see this in your terms then fine but just because you use Darwin's terminology does not make either of you correct.
I'm relating the knowledge acquired by science and not thinking about something, fixating on untested ideas that don't have evidence and declaring those ideas into a belief system. That seems to describe the path your ideas are on.
It just means you can communicate more easily with those who share your beliefs.
I can communicate with those that accept science on the basis of understanding and evidence. They aren't telling me things and ignoring what I'm saying or doing it without providing sound arguments with evidence and reason.
The earth can be defined as "flat" but we don't do it because it makes the math too complicated.
We don't do it, because the evidence doesn't warrant it.
Darwin has complicated the means by which species change and overlooked the mechanisms.
Darwin was the first person to come up with a mechanism. How do you not seem to know any of this and still come off sounding like you are the only expert on the thread?
Something you made up that has a secret meaning known only to you. It has no apparent value, use or necessity in a conversation about biology or science in general.
It cannot be demonstrated to be true or meaningful.
But all other life forms including the extinct homo sapiens
Not extinct. It is the extant species of humans. How do you not know or understand this. Why have created this unusual idea that has no basis in fact?
It is not logically possible to be true or false, since
Homo sapiens exist. Two of them are posting back and forth in this conversation.
We experience reality in terms of our beliefs
I would agree if we isolated to what you have presented. It has no basis in fact. Is often contrary to known information and you can only repeat the claims without any seeming ability to defend the claims.
but the others experience it in terms of what they know.
Meaningless given the fact that nothing you are attributing to any group or species you've mentioned can be demonstrated. Some of the species aren't known to exist outside of your claims.
Their brains come to reflect reality. Their brains are the models of reality itself and the process results from the wiring of the brain with which they perceive reality and gain experience. This is the nature of consciousness which is individual and which Darwin couldn't see.
Apart from most of this not making much sense, Darwin didn't need to focus on consciousness or consider it at all to successfully come up with a theory of evolution and a mechanism to drive it. Which he did and for some reason you have developed a belief that denies this and conjures up its own facts from apparently out of your own ignorance of the subject.
I can't see how we could have a meaningful discussion given all I have seen. You have what appears to be a belief in things you have made up and with meanings you may attribute but keep to yourself. The things have no evidence and none is ever offered. You present them as universal facts that only you seem to know. You have a belief system. That's fine, but it isn't science or fact and there is no reason for me to consider anything you have stated.
You offer no reason for me to press on and continue engaging you. I don't subscribe to your belief system. Based on your posts, it isn't fact-based or determined through scientific rigor. There is no common ground between what you offer and the knowledge of biology I've acquired through study and research. You believe things for your own personal reasons and needs and I accept what I have learned based on logic, reason and evidence.
It was interesting to a point, but I think I've learned all that there is to learn here. Have a good day.
