Growth is a developmental process, not a random selection process.   The map for the\u00a0developmental sequence, one first roles of the genetic code, charts a developmental path.<\/p>\n<p>The question would be, how can genetic evolution alter the developmental path as a way of altering the organism that develops?    Somehow the genome serves to prompt a set of branching paths of developmental processes throughout a developing organism, and to then coordinate the limits they come to in maturity.<\/p>\n<p>Such a record of coordinated branching developmental paths would then be seen as what guides development. If so, might it not also suggest that the functional variations of the genome could primarily occur by extending and adjusting the developmental path?<\/p>\n<p>Then the genome could be self-healing except near the extremities of the developmental paths it leads, and so perhaps solve several of the puzzles of rapid coordinated multi-level evolution at one time.  The larger implication though, what makes it actually plausible, is this would then make mutation not random, but accumulative, local and branching.<\/p>\n<p>It could occur on all branches at once, preferentially.   What really got my attention was realizing that this would make multiplying variation *AT the point of successful variation* the rule.<\/p>\n<p>That would make genetic variation an active environmental exploration process.   Branching would then explore the environment of potentials in something of the same manner as earth worms or ants probe around in finding a path. \u00a0Successful variation is then followed by multiple variations on it and extending from it.    That solves other major problems like complex co-evolutions.<\/p>\n<h3 style=\"text-align: center;\">That sort of &#8216;mutation&#8217; could be *path finding* and essentially exploratory in the environment<\/h3>\n<p>It would then be expected to show up in the data as evolutionary change in growth spurts, as is clearly shown for G. tumida, and always implied by the evidence of punctuated equilibrium.<\/p>\n<p>Does a system design allowing rapid whole system variation in coordination with its environment fit  the pattern of punctuated equilibrium?   I think it provides the one big thing missing from every other theory.<\/p>\n<p>It allows for divergence followed by exploration and then maturation, breaking from and remaking a stable form.    Would you then need to treat both mutation and selection as one interactive process and as one transient dynamic event, a single \u2018thought\u2019 of combined organism\/environment learning?<\/p>\n<p>It takes a little getting used to, but it\u2019s tempting.     The final and perhaps best piece, the \u2018coupe de gras\u2019, is you don\u2019t need to exlude the other kinds of evolutionary processes.   They can all still operate, in tandem.<\/p>\n<p>Thus, I think, all the big missing pieces are covered and no new ones created!<\/p>\n<p>pfh<\/p>\n<p>I have good piece in Cosmos &amp; History giving an overview of how to identify and investigate natural systems that \u2018think for themselves\u2019 in this way, starting from that perennially\u00a0curious bit of evidence that points to them, systems that behave as a whole, with no means for storing the rules they are implicitly following! <a href=\"http:\/\/www.cosmosandhistory.org\/index.php\/journal\/article\/view\/102\/203\"> Life\u2019s Hidden Resources for Learning<\/a><\/p>\n<p>&nbsp;<\/p>\n<p><em><br \/>\n<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Letter to John Smart, I\u2019m very interested in your Evo-Devo Universe project. \u00a0I also found some interesting examples of development, that operates by multi-level selection. \u00a0Below is a bit of a very nice clear example, a case of punctuated equilibrium occurring by a series of rapid evolutionary progressions (spurts), for a plankton species, G. tumida. &hellip; <a href=\"https:\/\/synapse9.com\/signals\/multilevel-selection_devo-evo_\/\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">Multilevel selection in evolution &#8211; Devo-evo?<\/span> <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_crdt_document":"","footnotes":""},"categories":[6],"tags":[],"class_list":["post-880","post","type-post","status-publish","format-standard","hentry","category-mail"],"_links":{"self":[{"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/posts\/880","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/comments?post=880"}],"version-history":[{"count":0,"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/posts\/880\/revisions"}],"wp:attachment":[{"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/media?parent=880"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/categories?post=880"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/synapse9.com\/signals\/wp-json\/wp\/v2\/tags?post=880"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
