That would be a form of speciation of the individual.
I said there is no such thing as "species" at all and you say I believe an individual can change his species.
Obviously you are deconstructing my sentences in your terms rather than mine. 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.
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". There remains the logical inconsistency that if the species Evolved according to "fitness" then each generation must be fitter than the last.
I can parse your sentences accordingly.
More likely small changes accumulated over time from one generation to the next. But this runs counter to what you said above where you claim species reproduce new species individually.
You can't step into the same river twice. This is reality not some philosophical precept. For every practical purpose every individual is a different species than its parents or siblings. I have a virtually "identical" twin who's two years older. The fixation on what individuals have in common is what led to Darwin. Individuals are an amalgam of their parents and hence are much more different than the rest of their "species' and more like their siblings. No doubt when bottlenecks appear most individuals have a far higher probability of being more closely related to other survivors. When the tamest wolves were selected to breed dogs each selected individual was more likely to be closely or distantly related to those selected than those which were not.
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. It just means you can communicate more easily with those who share your beliefs. The earth can be defined as "flat" but we don't do it because it makes the math too complicated. Darwin has complicated the means by which species change and overlooked the mechanisms.
But only the genetic portion of that is heritable. Experience is an acquired characteristic that is not heritable. Like calloused hands.
In
homo omnisciencis this is very true. But all other life forms including the extinct
homo sapiens this is not true. We experience reality in terms of our beliefs but the others experience it in terms of what they know. 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.
