Hi Thmsberry,
quote: First, the request was for a reference to someone authoritative who defines the Modern Synthesis as you do. None of the books you mention could do that since they are well over a half century old and so could have no foreknowledge of future theories to distinguish from the Modern Synthesis. Second, let's take a look at your references:
Here is a list of reasons why your references do not support your point that the Modern Synthesis does not include developments in genetics after 1944:
I think the whole issue is that you see the Modern Synthesis as the blending of disparate theories within biology, while the rest of us see it as the blending of entire sciences within biology. So when you say this:
quote: Understand, we don't see the unification as being with Mendellian genetics, but rather with the entire science of genetics. Hence, when horizontal mechanisms were added to genetics it took place amidst the backdrop of the Modern Synthesis. The Modern Synthesis is not a theory but a perspective, one that views Darwinian evolution and genetics as compatible rather than antithetical. The discovery of horizontal mechanisms only reinforced this view. This is where we have such a problem with your view. How can you supplant something that is still true? The Modern Synthesis was the recognition that Darwinian evolution and genetics are compatible, and we still believe this to be true. Though we've learned much since the 1940s about both evolution and genetics, how could something that remains as true today as it was then be supplanted? You can say that originally the Modern Synthesis didn't know about horizontal mechanisms, but it didn't specifically exclude them (why would it, after all), and it certainly didn't expect science would remain static, and so subsequent developments were naturally to be expected. But those developments only strengthened the belief that Darwinian evolution and genetics are compatible.

The different doctrines of evolution will certainly toward to unification and to a new synthesis.

But your side has not presented one shread of evidence from an authoritative source that states that current theory of Evolution is properly called the Modern Synthesis.
quote:
And the authoritative quote that shows that the Current Synthetic theory grew and grows and around the original synthesis. This shows inarguably that the theories are distinct.
The current Synthetic Theory has grown around that original synthesis. It is not just one single hypothesis (or theory) with its corroborating evidence, but a multidisciplinary body of knowledge bearing on biological evolution, an amalgam of well-established theories and working hypotheses, together with the observations and experiments that support accepted hypotheses (and falsely rejected ones), which jointly seek to explain the evolutionary process and its outcomes. These hypotheses, observations, and experiments often originate in disciplines such as genetics, embryology, zoology, botany, paleontology, and molecular biology. Currently, the "synthetic" epithet is often omitted and the compilation of relevant knowledge is simply known as the Theory of Evolution. This is still expanding, just like the "holding" business corporations that have grown around an original enterprise, but continue incorporating new profitable enterprises and discarding unprofitable ones.pg 7961. Ayala, Francisco J. and Walter M Fitch. "Genetics and the origin of species: An Introduction." Proceedings of the National Academy of Sciences. USA Vol 94 7691-7697. July 1997.
The combination of the Mendelian theory of heredity and the Darwinian theory of evolution has come to be called variously the Modern Synthesis, or the synthetic theory of evolution, or neo-Darwinism.Evolution, p. 10, Mark Ridley, Oxford University Press, 1997.
We now understand that natural selection is just one of a number of processes that can lead to evolution. This knowledge has resulted in the development of a more complete understanding of genetic changes that is usually described as the synthetic theory of evolution. This is essentially a combination of Charles Darwin's concept of natural selection, Gregor Mendel's basic understanding of genetic inheritance, along with evolutionary theories developed in the 20th century by population geneticists and molecular biologists.Synthetic Theory of Evolution, Dennis O'Neil, Palomar college.
The combination of Darwinian natural selection and Mendelian genetics is called the synthetic theory of evolution.
The final result was a triumph of intellectual organization, a coming together of evidence from many disciplines to produce what came to be known as the New Evolutionary Synthesis.Blueprints: Solving the Mystery of Evolution, p. 182, Maitland A. Edey, Donald Johanson, 1990.
quote:
Face it, the original synthesis from the 30s and 40s was called the Modern Synthesis. This is a fact. The Synthetic theory came a lot later (late 70's early 80s) This also a fact. The synthetic theory is most popularly called the Current Synthesis, the Synthetic theory, or simply the Theory of Evolution.

But this is simply not what I am doing. The fragments I am presenting are just to get Percy's attention. In post 13 and 31 I refer to you and ask that Percy analyze the exchanges in detail.
