A paper appeared recently in Science that reminded me of one of my favorite toys when I was a kid — a rolling-ball maze.
Darwinian evolution is a tinkerer. It can fiddle a bit with pre-existing IC systems, but is incompetent to build new ones.
The focus of the feature is not so much Joe Thornton as it is intelligent design.
As always, the work is solid and interesting, but is spun like a top to make it appear to support Darwinian evolution more than it does.
The authors of a recent paper discuss their results in terms of the origin of multicellularity on earth.
