0034 To review.

The situation level of the following diagram addresses “adaptation”.  The content level concerns “phenotype.  This two-level interscope touches base with the authors’ biological expertise.

The above interscope veils a more intuitive content level, where the normal context is what is happening_3a, the actuality is some sort of activity_2a and the potential is that ‘something’ is happening_1a.

Finally, depending on the content level, there are two situation-level actualities_2b available.

The first concerns signals.  The second entails signs.

0035 Is there another way to diagram evolution?

One answer is that adaptation₂ and phenotype₂ are actualities in two nested forms.  Together, they constitute an intersection, defined as an actuality₂ composed of two actualities.

For roads, an intersection is where two roads meet.   It is a single actuality constituted by two actualities.  On top of that, it is full of contradictions, hence the necessity of traffic regulations.

The intersection of adaptation₂ and phenotype₂ is no different.   Each arises from a distinct potential.  That potential situates a content-level actuality.

0036 Here is the natural history side of Neodarwinism.

The normal context of natural selection_3b brings the actuality of adaptation_2b into relation with a niche_1b.  The niche_1b is the potential_1b of an actuality independent of the adapting species_2a. 

Notably, Newson and Richerson are not aware that the actuality independent of the adapting Homo genus_2a is … um… found in Razie Mah’s masterwork, The Human Niche.  To some degree, this ignorance explains the hidden ingredient,discussed earlier.

Here is the genetics side of Neodarwinism.

The normal context of body development_3b brings the actuality of the phenotype_2b into relation with its genotype_1b.  The genotype_1b is the potential_1b of each individual specimen’s DNA_2a.

0037 Now the actualities of adaptation₂ and phenotype₂ constitute a single actuality, which may be labeled “individual”, “species” or “genus”.  Here, the term, “species”, is used.

0038 This relational structure is developed in Razie Mah’s e-books, Speculations on Thomism and Evolution and Comments on Dennis Venema and Scot McKnight’s Book (2017) Adam and the Genome, along with other works in the series, A Course on Evolution and Thomism.
