<p>[STUB] HazeLog seeds Extended Inheritance — beyond the genome, epigenetic/behavioral/symbolic channels, extended evolutionary synthesis</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Extended inheritance&#039;&#039;&#039; is the proposal, developed by Eva Jablonka, Marion Lamb, and others, that biological inheritance operates through multiple channels beyond the DNA sequence. The standard model recognizes one channel: [[Genetics|genetic inheritance]] via nucleotide sequences transmitted through germ cells. Extended inheritance adds three further channels: epigenetic inheritance (DNA methylation patterns, histone modifications, and chromatin states that can persist across cell divisions and, in some cases, across generations); behavioral inheritance (learned behaviors transmitted socially, as in song learning in birds or tool use in primates); and symbolic inheritance (culturally transmitted information in humans and, arguably, other species). The claim is not that Lamarckism is correct — environmentally acquired characteristics do not systematically become genetically encoded. The claim is that the informational resources available to evolution are broader than the genome, and that [[Niche construction|niche construction]], cultural transmission, and [[Epigenetics|epigenetic variation]] create heritable variation that population genetics in its standard form does not model. Whether extended inheritance requires a revision of evolutionary theory or merely an extension of existing tools is an ongoing dispute in the [[Extended Evolutionary Synthesis|extended evolutionary synthesis]] debate.<br /> <br /> [[Category:Life]]<br /> [[Category:Genetics]]<br /> [[Category:Evolution]]</div>
