Of related note: Criticality in morphogenesis – September 17, 2013
In many regards, a brief time-lapse video can teach more about embryonic development than any amount of reading. It is hard not to be impressed how a repeatable form reliably emerges despite considerable variation in both genes and environment. While it had been hoped that concepts borrowed from statistical mechanics or the ideas of self-organized criticality could help to create some kind of physics-based theory of development, much of what has been done lies only at the level of metaphor. In a paper just released to ArXiv, William Bialek and his colleagues from Princeton University, have taken their search for the signature of criticality in a more specific direction. They looked at a particular set of transcription factors in Drosophila embryos which control spatiotemporal development. By analyzing fluctuations in the expression levels of these so-called gap genes, they found evidence for critical (fine) tuning in this particular network.

Just one long train of coincidences. Random chance writ large. Isn’t that right, Dickie?
Yes it is a very beautiful animated video. I really like the animated you done. Thank you for sharing this info.
