Sex and Death – Chapter Three: Sex and Death – Chapter Three The Gene’s Eye View of Evolution
Replicators and Interactors
Sex and Death – Chapter Three: Sex and Death – Chapter Three Outline
3.1 Gene Selectionism vs. received View
Three Arguments for Gene Selectionism
3.2 Replicators not Organisms
3.3 Bookkeepings Argument
3.4 Extended Phenotype
Sex and Death – Chapter Three: Sex and Death – Chapter Three What Is a Gene?
information copied to next Generation
Germ line and somatic line distinction
Sex and Death – Chapter Three: Sex and Death – Chapter Three What are 'Interactors'?
Entities that interact with environment
Adaptions for interaction in each generation
Sex and Death – Chapter Three: Sex and Death – Chapter Three Organisms – Survival Machines of the Genes
Beneficiars of interaction and adaption
Compete in construction of interactors
Replicator Complexes influence others ('outlaw genes')
Sex and Death – Chapter Three: Sex and Death – Chapter Three 3.2 The cumulative Status of Selection
Do organisms form lineages?
What is cumulatively reproduced –
Replicators or Interactors?
Sex and Death – Chapter Three: Sex and Death – Chapter Three 3.3 The Bookkeeping Argument
Replicators keep track of evolution
What about Junk – DNA?
Gene Selectionism – Replicator Selectionism
Sex and Death – Chapter Three: Sex and Death – Chapter Three 3.4 The extended Phenotype
What is an Organism?
Genetic Effects on Phenotype
2 Dimensions of Replication:
1. Distinction outlaw/cooperator genes
2. Site of interaction ('arms' of genes)
