# Evolution is smart enough to do subtraction, not addition

From “Mystery of Disappearing Bird Digit Solved?” (ScienceDaily, Sep. 4, 2011), we learn the answer to one of life’s little mysteries: How does the three-toed bird foot map onto the five-toed mammal foot:

Evolution adds and subtracts, and nowhere is this math more evident than in vertebrates, which are programmed to have five digits on each limb. But many species do not. Snakes, of course, have no digits, and birds have three.

Yale scientists now have a good handle on how these developmental changes are orchestrated in the embryo. But there is still one outstanding debate on birds: Which digits are they? A thumb with index and middle fingers, or the index, middle and ring fingers?

As it turns out, a Yale genomic analysis shows that on a three-toed foot, the first digit starts where the index finger on a hand would be.

Can evolution easily add functional digits to vertebrates? Subtraction, it seems, has always been easier. There’s a message in that about how evolution really works – for those who care.

There are people with perfectly formed extra fingers and toes. http://www.christianpost.com/news/polydactyly-cuban-man-with-24-digits-says-they-are-a-blessing-54764/ Arguing that this doesn't happen is wrong and silly.Petrushka

HMM, Math just so happened to 'emerge' from a material neo-Darwinian basis? I don't think so! Math always dictates how material reality behaves, never does material reality dictate how math should behave!!! notes to that effect:
‘In chapter 2, I talk at some length on the Schroedinger Equation which is called the fundamental equation of chemistry. It’s the equation that governs the behavior of the basic atomic particles subject to the basic forces of physics. This equation is a partial differential equation with a complex valued solution. By complex valued I don’t mean complicated, I mean involving solutions that are complex numbers, a+bi, which is extraordinary that the governing equation, basic equation, of physics, of chemistry, is a partial differential equation with complex valued solutions. There is absolutely no reason why the basic particles should obey such a equation that I can think of except that it results in elements and chemical compounds with extremely rich and useful chemical properties. In fact I don’t think anyone familiar with quantum mechanics would believe that we’re ever going to find a reason why it should obey such an equation, they just do! So we have this basic, really elegant mathematical equation, partial differential equation, which is my field of expertise, that governs the most basic particles of nature and there is absolutely no reason why, anyone knows of, why it does, it just does. British physicist Sir James Jeans said “From the intrinsic evidence of His creation, the great architect of the universe begins to appear as a pure mathematician”, so God is a mathematician to’. Granville Sewell - Professor of Mathematics - University of Texas El Paso Michael Denton – Mathematical Truths Are Transcendent And Beautiful – Square root of -1 is built into the fabric of reality – video http://www.metacafe.com/watch/4003918/ THE GOD OF THE MATHEMATICIANS - DAVID P. GOLDMAN - August 2010 Excerpt: we cannot construct an ontology that makes God dispensable. Secularists can dismiss this as a mere exercise within predefined rules of the game of mathematical logic, but that is sour grapes, for it was the secular side that hoped to substitute logic for God in the first place. Gödel's critique of the continuum hypothesis has the same implication as his incompleteness theorems: Mathematics never will create the sort of closed system that sorts reality into neat boxes. http://www.faqs.org/periodicals/201008/2080027241.html as should be blatantly obvious, mathematics cannot be grounded in a materialistic worldview; Mathematics is the language with which God has written the universe. Galileo Galilei The Unreasonable Effectiveness of Mathematics in the Natural Sciences - Eugene Wigner Excerpt: The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it and hope that it will remain valid in future research and that it will extend, for better or for worse, to our pleasure, even though perhaps also to our bafflement, to wide branches of learning. http://www.dartmouth.edu/~matc/MathDrama/reading/Wigner.html The Underlying Mathematical Foundation Of The Universe -Walter Bradley - video http://www.metacafe.com/watch/4491491 The Five Foundational Equations of the Universe and Brief Descriptions of Each: http://docs.google.com/Doc?docid=0AYmaSrBPNEmGZGM4ejY3d3pfNDdnc3E4bmhkZg&hl=en How can it be that mathematics, being after all a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things? — Albert Einstein “… if nature is really structured with a mathematical language and mathematics invented by man can manage to understand it, this demonstrates something extraordinary. The objective structure of the universe and the intellectual structure of the human being coincide.” – Pope Benedict XVI "The reason that mathematics is so effective in capturing, expressing, and modeling what we call empirical reality is that there is a ontological correspondence between the two - I would go so far as to say that they are the same thing."
