C. Elegans is a wonderful creature. It’s a nematode, so it looks like a tiny worm. It is one of biologists’ favorite model organisms and we know a lot about it.
It has roughly 1000 cells, and its cell lineage is almost identical for every individual. This creature has been mapped out more thoroughly than any other species on the planet. You can browse a map of its cells through the OpenWorm Browser. The hermaphrodite has 302 neurons and its connectome is completely known.
It is silly to think we’ll be simulating human minds any time soon, when people have been trying to simulate C. Elegans for decades now.
