And one more question. I am assuming when he talks about the moon on a tower there is no rotation involved.  But he doesn't specify that.  If there is a rotating earth with the moon on a tower, isn't that a different issue?

You mean, the moon is on a tower planted on the earth, which rotates (so the moon stays over a fixed location on the earth's surface)?  Or the moon is on a tower planted on something else, while the earth rotates nearby (so the moon's position above the earth's surface changes)?
I somehow missed your post before.

I mean if the moon is attached by a tower to the earth.

I think we covered this, but one more time.

Several different situations.  If the moon is on a tower, so it is exactly still in regards to the earth.  One bulge?

But if on a tower, and the earth is rotating?  24 hour a day rotation that is? One bulge or two?

If the moon is on a tower, no 24 hour spinning, but the two are rotating around their shared center of gravity monthly?  What then? (is that even possible?)

A new and more robust evolutionary synthesis is emerging that attempts to explain macroevolution as well as microevolutionary events. This new synthesis emphasizes three morphological areas of biology that had been marginalized by the Modern Synthesis of genetics and evolution: embryology, macroevolution, and homology. The foundations for this new synthesis have been provided by new findings from developmental genetics and from the reinterpretation of the fossil record. In this nascent synthesis, macroevolutionary questions are not seen as being soluble by population genetics, and the developmental actions of genes involved with growth and cell specification are seen as being critical for the formation of higher taxa. In addition to discovering the remarkable homologies of homeobox genes and their domains of expression, developmental genetics has recently proposed homologies of process that supplement the older homologies of structure. Homologous developmental pathways, such those involving thewntgenes, are seen in numerous embryonic processes, and they are seen occurring in discrete regions, the morphogenetic fields. These fields (which exemplify the modular nature of developing embryos) are proposed to mediate between genotype and phenotype. Just as the cell (and not its genome) functions as the unit of organic structure and function, so the morphogenetic field (and not the genes or the cells) is seen as a major unit of ontogeny whose changes bring about changes in evolution.


If "macroevolutionary questions are not seen as being soluble by population genetics" then those people (including the folks here) who have been claiming that macroevolutionary questions are soluble by population genetics, have been going down the wrong path.
And everyone started down the wrong path since the time of Darwin.
But it is not necessary to continue going down the wrong path.
Instead:
"the developmental actions of genes involved with growth and cell specification are seen as being critical for the formation of higher taxa."

So the focus now shifts to the plausibility of higher taxa being formed by changes to "growth and cell specification genes" (regulatory genes).
The first point is that the published material (which I have posted) shows that higher taxa being formed by changes to "growth and cell specification genes" (regulatory genes) is indeed plausible. Indeed credible.
This is something that folks here cannot even deny. So everyone goes quiet.
