Developmental Biology

Last update: 21 Apr 2025 21:17
First version:

The science formerly known as embryology.

Self-organization and pattern formation --- physico-chemical mechanisms; genetic markers; how the genes control the physical processes. Mathematical modelling in this field seems largely confined to the physical mechanisms of pattern formation; do we have any well-confirmed theories in this area? Do we have so much as a single pair of known Turing morphogens? (John Maynard Smith says we do not, and would almost certainly know.) (True in 1995 or 1996, when I wrote it, but not since 2012. It remains the case that Turing's mechanism doesn't seem to be much used by actual biology...)

Evolutionary issues: get their own notebook.

"Model systems" for developmental biology --- Drosophila, C. elegans, zebra fish, mice, frogs, sea urchins, salamanders, slime molds; what do plant or arthropod developmentalists study? Just how far can we extrapolate from these beasts to the other ~10^8 metazoan species? (That gets back to evolutionary issues.)
