       | Back at FreeGenes we synthesized all of the genes from this
       | organism with codon optimization for Escherichia coli
       | (https://stanford.freegenes.org/collections/gene-
       | sets/product...), the workhorse of synthetic biology. If you
       | combine the right transcriptional and translational elements, you
       | should be able to build a fully modular genome from this gene
       | set! We also did a couple other organisms in pursuit of this
       | modular genome. As a nice bonus, you can also easily do in-vitro
       | cell-free experiments since the codon tables are nice (and I've
       | heard from Kate Adamala's group that JCVI-Syn3 has pretty bad
       | cell free, though that was a couple years ago)
       | 
       | It's important to note that JCVI-Syn3A has a LOT of problems when
       | it comes to its practical use. There just isn't enough energy
       | being put into making an understandable and practical
       | modular/minimal genome.

           | detailed the image the less likely it arose naturally.
           | 
           | The fact that even now, no one has any idea of how to create
           | the basic forms of life shows the astonishing amount of

           | alien species or a programmer of a simulation. There's too
           | much information to spontaneously generate, and we have never
           | seen life come from non life.
           | 
           | The theory has been essentially banished from academia for
           | political, not scientific, reasons, but Michael Behe and

               | reality the structure is being assembled slowly on the

               | BTW it's important to remember that modern evolutionary

               | (albeit related) scientific question and one for which we

             | 
             | 4) Evolution by random natural processes is not possible
             | without deliberate nudges.
             | 
             | Is the claim here that 1-3 is simply not possible without
             | an intelligent entity intervening in the natural laws? If
             | so, I'm personally fine with it. God (who is the most
             | popular potential Intelligent Designer) has always been a
             | God of the Gaps. In the future, I am pretty confident we'll
             | figure out the explanations using just the physical laws of
             | the universe.
             | 
             | But if the claim also includes 4, then I think it can be
             | discarded with a high confidence. We can already observe
             | how evolution works at the virus and bacteria level. We
             | have found the transitional fossils [0]. The science of
             | evolutionary development biology [1] is already giving us
             | great insights into how organisms translate the genetic
             | code to build our complex bodies. It also shows how the
             | same genes have been reused across species (e.g., the genes
             | for eyes in the house fly and humans are the same). We

               | work if is anything missing, so you can't evolve part
               | way. E.g. a mousetrap that lacks the spring doesn't work
               | at all. Therefore, evolution couldn't create the
               | irreducibly complex mechanisms found in biology. QED.
               | 
               | The big flaw that I see is that he looks at the problem
               | of creating irreducibly complex mechanisms by addition,
               | but they can easily be produced by _subtraction_. As an
               | analogy, an arch is irreducibly complex because if you
               | take out any stone, it collapses, so you can 't build it
               | one stone at a time. But you don't build an arch this
               | way. Instead, a support is built and the stones are put
               | on top of the support, one at a time. When you take the
               | support away, now you have an irreducibly complex
               | structure. Similarly with biology, something can evolve
               | step by step with redundancy, and then pieces are removed
               | by evolution, ending up with an irreducibly complex
               | mechanism that Behe views as impossible.
