Manuel de Landa: species and ecosystems Manuel de Landa: species and ecosystems Presentation Transcript

  • species and ecosystems Manuel de Landa
  • species and ecosystems
  • structure generating processes species and ecosystems
  • structure generating processes species and ecosystems [gene pool of species]
  • structure generating processes species and ecosystems [gene pool of species] historical outcome of a sorting process
  • structure generating processes species and ecosystems [gene pool of species] accumulation of historical outcome of a sorting process genetic materials by selection pressures
  • structure generating processes species and ecosystems [gene pool of species] accumulation of historical outcome of a sorting process genetic materials by selection pressures consolidation
  • structure generating processes species and ecosystems [gene pool of species] accumulation of historical outcome of a sorting process genetic materials by selection pressures consolidation reproductive isolation
  • structure generating processes species and ecosystems [gene pool of species] accumulation of historical outcome of a sorting process genetic materials by selection pressures consolidation reproductive isolation
  • reproductive isolation
  • reproductive isolation external causes
  • reproductive isolation external internal causes causes
  • flow of genes reproductive isolation external internal causes causes
  • flow of genes reproductive isolation barriers external internal causes causes
  • flow of genes reproductive isolation barriers external internal causes causes encapsulated in packets
  • flow of genes reproductive isolation barriers external internal causes causes encapsulated in packets stratified system
  • flow of genes Organisms and genomes may thus be regarded as compartments of the biosphere through which genes in general circulate at various rates and in which individual genes and operons may be incorporated if of sufficient advantage. KWJeon & JFDanielli, 1971

  • An autopoietic machine is a machine organized (defined as a unity) as a network of processes of production (transformation and destruction) of components which: (i) through their interactions and transformations continuously regenerate and realize the network of processes (relations) that produced them; and (ii) constitute it (the machine) as a concrete unity in space in which they (the components) exist by specifying the topological domain of its realization as such a network. h. maturana - f. varela
