I find this line of reasoning to be inconsistent and unfair. You have yourself argued against what I have said as wrong yet admit you are a layman. Yet at the same time want to claim me a layman who doesn’t understand the literature I am citing. So it seems fine for you. Yet when I do it it's wrong. I also think it’s a misrepresentation of things. Primarily I have made simple and basic claims which are repeated in the EES papers that don’t really need a higher level of understanding. The thing is a claim is made and it is a simple claim and one that cannot be misconstrued. I think using the tact of a lack of understanding to discredit what I am saying is being misused and doesn't address the content of what is being said.
For example, you challenged the claim that the EES said that the SET claimed that natural selection was the sole source of evolutionary change and that I misunderstood things. I then showed you that this is exactly what the papers said and you agreed. I then went about showing how the EES was correct on this by provided support for outside the EES from mainstream papers which you also acknowledged.
As mentioned I have basically made a simple claim about what the EES claims about the differences between the EES and the SET. It is not a matter of a special and deeper understanding of these basic issues. Primarily the EES is saying that the SET claims that the sole cause of evolutionary change is Natural Selection and that the source of variations is random.
As opposed to the EES where the cause of evolution is expanded to include the EES forces of niche construction, inheritance beyond genes, developmental bias, and plasticity. That these EES forces are nonrandom and can produce adaptive and heritable variations before and without natural selection. That this expands the causes of evolution and adds more explanatory power. How is this so hard to understand? You have acknowledged this and also acknowledged this is what the papers have said. I can show you the posts.
Some may want to dispute this by claiming that there is more to evolution than that. But that is not the point. That may be their view of things but it doesn’t change the fact that this is what the EES is basically saying.
But attacking the person is not addressing what the source says. Why would the source be placing so much emphasis and focus on this? Why would they for example say something like this? This comes from the EES itself and talks about the basic differences between the EES and the SET
How the EES differs from the Modern Synthesis
Like the EES, the Modern Synthesis also represents a particular way to understand evolution. It primarily focuses on genes:
- new variation arises through random genetic mutation
- inheritance occurs through DNA
- natural selection of genes is the sole cause of adaptation

Now that quote clearly states what I have been saying and that’s all I have been saying. This is a summary of what the difference is and it is printed in black and white. There are no hidden meanings and no amount of further understanding is going to change these basic differences. So explain to me how this is wrong and doesn’t mean exactly what it says.
This is a good example of how using a lack of understanding based on a straw man. It is an extreme and false claim to say that the argument that the SET lacks explanatory power should mean that it should be totally and immediately rejected. We both know that science doesn't work that way and that even with Lamarckism and how the MS came about was gradual and evolved.
So it follows that using this false claim as evidence I don't understand things is also false. You are also assuming that I don't think the SET has any explanatory power. You are taking things to extremes. I have not said the SET completely lacks explanatory power. I have actually said the EES has more explanatory power than the SET which is a different thing altogether.
But here's the main point. You claim that I am misunderstanding the EES paper when it says that the SET lacks explanatory power and the EES offers a better explanation for what we are seeing in how living things evolve. If that is the case then please explain what the EES papers mean by the following.
This recognition of a variety of distinct routes to phenotype–environment fit furnishes the EES with explanatory resources that traditional perspectives lack.
Does the extended evolutionary synthesis entail extended explanatory power?
“We now possess a more pluralistic theory, recognizing more factors and interactions than included in the classical model and with expanded explanatory capacity” Müller and Pigliucci (2010: 276)
“By encouraging greater reflection on the plurality of the underlying causes of evolution, the EES should deepen understanding of the mechanisms of evolution” Laland et al. (2015: 10)
“The EES […] represents a pluralistic, process-based framework of dynamical interactions between a multitude of evolutionarily effective factors and generates its own set of evolutionary predictions that make it clearly distinct from the MS account” Müller (2017: 8)
“The ongoing shift from a population-dynamic account to a causal-mechanistic theory of phenotypic evolution brings with it a significantly expanded explanatory capacity of evolutionary theory. It has become possible to address phenomena of evolution that were untreatable by the MS” Pigliucci and Müller (2010b: 12)
“[…] if the current efforts succeed, we will expand the scope and explanatory tools available to evolutionary biologists” Pigliucci (2008: 322)
“The EES also raises new questions, informs established lines of inquiry and helps to provide more complete explanations for evolutionary phenomena” Laland et al. (2015: 9)
“Instead of privileging selected mechanisms such as random variation, genetic control and natural selection, the multitude of factors that dynamically interact in the evolutionary process will be better expounded by a pluralistic theory framework” Müller (2017: 9)
We have presented a general contrastive framework suitable for evaluating the goodness of scientific explanations. It is able to distinguish why and when explanations of the EES are better than prevailing SET explanations. Our framework also suggests that there might be an overlooked diversity of explanatory standards within EES, and that making different areas of research coherent requires an assessment of the standards that operate within each contributing field.
Does the extended evolutionary synthesis entail extended explanatory power?
let’s see what I have said about the EES. Basically, I have said that the EES claims that the SET takes a too narrow view of evolution by making natural selection the sole cause and driver of evolution and that variation is random. That is basically reflected exactly in the quote from the paper above.
I have also said that the EES claims that their view of evolution is more expansive and includes other sources of variations that are nonrandom and because of that are also adaptive and heritable before natural selection comes along. That these additional variations can bias natural selection and therefore can cause and drive evolution in a similar way to natural selection.
Yo make things simple and to show how the EES core assumptions differ from the SET here is a chart explaining the differences. Assumptions are a good representation of how the EES and the SET see things and are the basis for most theories in science. These assumptions support what I have been saying and don't need any further understanding as far as how they define the basic predictions of each view. Click on the image to enlarge
