Interesting things from UncommonDescent comments: What Do Organisms Mean? Stephen L. Talbott – Winter 2011 Excerpt: Harvard biologist Richard Lewontin once described how you can excise the developing limb bud from an amphibian embryo, shake the cells loose from each other, allow them to reaggregate into a random lump, and then replace the lump in the embryo. A normal leg develops. Somehow the form of the limb as a whole is the ruling factor, redefining the parts according to the larger pattern. Lewontin went on to remark: “Unlike a machine whose totality is created by the juxtaposition of bits and pieces with different functions and properties, the bits and pieces of a developing organism seem to come into existence as a consequence of their spatial position at critical moments in the embryo’s development. Such an object is less like a machine than it is like a language whose elements… take unique meaning from their context.[3]”,,, http://www.thenewatlantis.com/.....nisms-mean The face of a frog: Time-lapse video reveals never-before-seen bioelectric pattern – July 2011 Excerpt: For the first time, Tufts University biologists have reported that bioelectrical signals are necessary for normal head and facial formation in an organism and have captured that process in a time-lapse video that reveals never-before-seen patterns of visible bioelectrical signals outlining where eyes, nose, mouth, and other features will appear in an embryonic tadpole.,,, “When a frog embryo is just developing, before it gets a face, a pattern for that face lights up on the surface of the embryo,”,,, “We believe this is the first time such patterning has been reported for an entire structure, not just for a single organ. I would never have predicted anything like it. It’s a jaw dropper.”,,, http://www.physorg.com/news/20.....-seen.html Not in the Genes: Embryonic Electric Fields – Jonathan Wells – December 2011 Excerpt: although the molecular components of individual sodium-potassium channels may be encoded in DNA sequences, the three-dimensional arrangement of those channels — which determines the form of the endogenous electric field — constitutes an independent source of information in the developing embryo. http://www.evolutionnews.org/2.....54071.html [ Another problem for Darwinian theory. ] Ask an Embryologist: Genomic Mosaicism – Jonathan Wells – February 23, 2015 Excerpt: humans have a “few thousand” different cell types. Here is my simple question: Does the DNA sequence in one cell type differ from the sequence in another cell type in the same person?,,, The simple answer is: We now know that there is considerable variation in DNA sequences among tissues, and even among cells in the same tissue. It’s called genomic mosaicism. In the early days of developmental genetics, some people thought that parts of the embryo became different from each other because they acquired different pieces of the DNA from the fertilized egg. That theory was abandoned,,, ,,,(then) “genomic equivalence” — the idea that all the cells of an organism (with a few exceptions, such as cells of the immune system) contain the same DNA — became the accepted view. I taught genomic equivalence for many years. A few years ago, however, everything changed. With the development of more sophisticated techniques and the sampling of more tissues and cells, it became clear that genetic mosaicism is common. I now know as an embryologist,,,Tissues and cells, as they differentiate, modify their DNA to suit their needs. It’s the organism controlling the DNA, not the DNA controlling the organism. per ENV Body Plans Are Not Mapped-Out by the DNA – Jonathan Wells – video http://www.youtube.com/watch?v=meR8Hk5q_EM The Insurmountable Problem of “Form/Shape” for Darwinian Explanations – video (2016) https://www.facebook.com/philip.cunningham.73/videos/vb.100000088262100/1138468566166075/?type=2&theater http://www.uncommondescent.com/intelligent-design/dna-as-the-littlest-origami/
