also he's a biologist
The idea that I have pursued in biology for much of my career is the concept that goes under the name of a morphogenetic field. This term is used to describe the processes in space and time that organise and coordinate the various activities involved in the emergence of a whole complex organism from a single cell, or from a group of cells in interaction with each another.
he goes on to talk about the "field" model(like a gestalt, or maybe a computing cloud, i think?) vs. mechanism model.
also when he talks about making sense of DNA, he leaves out sequencing, which involves WHEN the genes activate. sequencing may literally make the difference between a bird and a dinosaur.
apparently, vertebrates are put together w/pretty much the same genetic toolkit. we all have about 20,000 genes, give or take a couple of K. and the genes for body shape, i.e. number of limbs, whther or not we have scales or feathers on our talons, etc., number only about 1,000. (you can get feathers instead of scales on your talons if you get your genes to fire off in a different order.)
saw it on the discovery channel. the biologist who talked about it, basically said that all biologists everywhere shit a whole bunch of bricks. i kinda did too.
if my genes had fired off in only slightly different order, i coulda been a wombat!
or a half-elf or a tiefling or some other related geekery.
