Following Murray Gell-Mann and others in considering complexity observer-dependent, conceptions of Spencer-Brown, of Luhmann and of Varela and Maturana are taken to draft a formal conception of observation and to discuss on its base suggestions like informational (Shannon), algorithmic (Solomonov, Kolmogorov, Chaitin), statistical (Crutchfield) and physical (Adami) complexity. Finally, in order to illuminate the concept of the observer further, the presumably indispensable aspect of complexity reduction is illustrated with the help of a Genetic Algorithm.","author":[{"@context":"https://schema.org","@type":"Person","name":"Manfred Füllsack"}],"contributor":[],"dateCreated":"2011-07-05","dateModified":"2014-05-26","datePublished":null,"headline":"Complexity and its observer.

through natural selection, there is no generally agreed explanation for why evolution leads to ever more complex organisms. Evolution yields organismic complexity because the universe is, in its very fabric, inherently complex, as suggested by Ilya Prigogine&#39;s work on dissipative structures. Because the universe is complex, increments in organismic complexity yield survival benefits: (1) more efficient extraction of energy and matter, (2) more flexible response to vicissitudes, (3) more effective search. J.J. Gibson&#39;s ecological psychology provides a clue to the advantages of sophisticated information processing while the lore of computational theory suggests that a complex computer is needed efficiently to perform complex computations (i.e. sophisticated information processing).</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;A Note on Why Natural Selection Leads to Complexity&quot;,&quot;attachmentId&quot;:34870587,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/8488872/A_Note_on_Why_Natural_Selection_Leads_to_Complexity&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/8488872/A_Note_on_Why_Natural_Selection_Leads_to_Complexity"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="37319936" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/37319936/Natural_Selection_and_Complexity">Natural Selection and Complexity</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="11929836" href="https://uned.academia.edu/GiorgioAiroldi">Giorgio Airoldi</a></div><p class="ds-related-work--abstract ds2-5-body-sm">The alleged Darwinian fundamental tenet that Natural Selection explains the complexity of life is controversial. While adaptationist narratives aims at formalizing it based on the hypothesis that phenotypic traits result from fitness optimization , mechanisms alternative to Natural Selection have been proposed to explain the tendency of organisms towards increasing complex designs. The thesis of this paper is that, in order to clarify to which extent Natural Selection or other forces are the relevant explicans, it is necessary to recognize that there is a wide range of radically different evolutionary facts, to which no univocal definition of complexity increase is applicable. To classify them, we introduce a bi-dimensional space by adding robustness to fitness as the second dimension to measure design and design changes. In this space, it is possible to distinguish the impact of selective and non-selective mechanisms behind each class of evolutionary fact, and the correspondent different classes of complexity increase.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Natural Selection and Complexity&quot;,&quot;attachmentId&quot;:57276875,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/37319936/Natural_Selection_and_Complexity&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/37319936/Natural_Selection_and_Complexity"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;continue-reading-button--sticky-ctas&quot;,&quot;attachmentId&quot;:30851618,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;workUrl&quot;:null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;download-pdf-button--sticky-ctas&quot;,&quot;attachmentId&quot;:30851618,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;workUrl&quot;:null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_30851618" style="display: none"><div class="scribd--being-converted-container">This document is currently being converted.
