The Extended Phenotype The Long Reach Of The Gene

Richard Dawkins' The Extended Phenotype — a revolutionary concept in evolutionary biology. Dawkins argues that a gene's effects are not limited to the body it inhabits. They extend into the environment: spider webs, beaver dams, bird nests, termite mounds, and parasite manipulation of hosts are all extended phenotypes. Covers 5 use cases: ① The extended phenotype concept — genes express effects beyond the body: spider webs, termite mounds, beaver dams are all extended phenotypes, as much a product of natural selection as eyes and legs ("Extended phenotype" "Gene's reach" "Evolutionary biology" "Dawkins theory" "Phenotype beyond body") ② The gene's eye view of evolution — natural selection acts on genes, not organisms. Genes build bodies and environments to increase their replication chances ("Selfish gene" "Gene-centered evolution" "Replicator theory" "Unit of selection" "Vehicle") ③ Animal artifacts as extended phenotypes — beaver dams, bird nests, caddis fly cases, spider webs, termite mounds are all extended effects of genes ("Animal artifacts" "Nest building evolution" "Beaver dams" "Spider webs" "Tool use") ④ Parasite manipulation of hosts — flukes in snails, toxoplasma in rats, cordyceps fungi in insects — parasites that alter host behavior are expressing their extended phenotype ("Parasite manipulation" "Host manipulation" "Behavioral ecology" "Parasite-host evolution") ⑤ Implications for evolutionary theory — how the extended phenotype concept transforms our understanding of adaptation, altruism, and the nature of the organism ("Evolutionary theory" "Adaptation" "Altruism" "Organism concept" "Dawkins contribution") Trigger when users say: "Extended phenotype" "Dawkins" "Gene's eye view" "Replicator" "Evolutionary biology" "Parasite manipulation" "Artifact evolution" "Nest building" "Selfish gene" "Gene selection" or mention: Richard Dawkins / Extended Phenotype / selfish gene / replicator / gene-centered evolution / animal artifacts / parasite manipulation / Dawkins extended phenotype.
