Paul McBride’s natural selection: A perfect nested functional hierarchy?

All organisms are big NFHs. In fact just the standard top-down layering of apparatuses, organs, tissues and cells is a nested functional hierarchy. In whatever way you layout a common descent Darwinian phylogenetic tree you have a unique simple common ancestor at the top and many complex NFH species at the bottom. So the problem of proving Darwinian macroevolution is to show how those complex NFHs arise by the RM+NS bottom-up process. I too think that NFHs cannot be produced that way, due to the concept explained by E.. niwrad

Descent with modification does not predict a nested hierarchy of shared traits. Ya see with evolution traits can be lost or gained and traits can be blended, forming a Venn diagram, not a nested hierarchy. Also just about anything can be placed into a nested hierarchy- it all depends on the criteria used. And the fact is the theory of evolution is OK without a nested hierachy as we do not see a nested hierarchy with prokaryotes. Joe

Explain to me this bafflegab:

…There is a reason why, despite of the power of software and hardware tools available today, evolutionists haven’t succeed so far to provide the least computer simulation of a real and functioning NFH generated by C&N.

Uh, we know EXPERIMENTALLY that RM+NS makes Unique Nested Hierarchies (UNH), not Nested Functional Hierachies (NFH). We know EXPERIMENTALLY by comparing the results of phylogenetic analyses against OBSERVED examples that RM+NS produces a UNH, and that phylogenetic methods reliably reconstruct their history.

Yeah, whoever said anything about nested "functional" hierarchy? Source please. All biologists talk about is a nested hierarchy of shared traits, many of which aren't functional in any major way (neutral mutations, flipping around of chromosome chunks, chromosomal fission and fusion, etc.).

Perhaps Eugenio could explain what a nested 'functional' hierarchy would look like in biology, I am not familiar with the phrase. What I referred to was a nested hierarchy caused by descent in diverging lineages derived from morphological or genetic characters, and I have never claimed anything about it being perfect (in fact I have discussed some of the ways that species trees and gene trees differ, showing the latter to be an imperfect representation of descent). paulmc
