EVO DEVO
|

General definition
* Evolutionary developmental biology (informally, evo-devo) is a field of biology that compares the developmental processes of different organisms to determinethe ancestral relationship between them, and to discover how developmental processes evolved.
* Evo-Devo is a combination of two disciplines within the field of biology: evolutionary biology anddevelopmental biology. Evolutionary developmental biology, then, or Evo-Devo for short, is a way to look at the way that the mechanisms of development have been influenced by evolutionary forces. Andthis, of course, is a logical collaboration between two different biological camps.
From Darwin to Post-Darwinian Models:
Evolution to Evolutionary Development
* The Darwinian model ofevolution encompasses three fundamental processes: variation, selection, and heritability.
* The post-Darwinian model of evolutionary development (evo-devo biology) requires us to consider variational(“evolutionary”) and heritable (“developmental”) processes as most fundamental to complex systems. Selection (“computation”) is a composite process occuring only in complex systems that have variation andreplication (inheritance). We can summarize this as an “evo compu devo” process model.
* While the term “evolution” can generically describe biological change, this is a bit misleading, as bothevolution and development are equally fundamental to complexity. To understand macrotemporal, macroscale selection (generalized “computation”) we must consider both processes.
The Evo Devo Universehypothesis proposes that, just like biological organisms, our universe itself is engaged in both evolutionary (variation, creativity) and developmental (hierarchy, replication, lifecycle) processEvolutioary variation is Random, Chaotic, Contingent:
Examples: Tree of Life, Vestigial Structures
* There’s no inherent directionality to (almost all) evolutionary emergence, other than...
