I commented:

Anders spoke of 2 million axons from the retina.

It seems we were all understating the case. According to Richard Dawkins,
in MOUNT IMPROBABLE,

`the human retina has about 166 million photocells' (p. 160).

Why am I bothering to post this `We Were Wrong'? Like, who really cares?
I dunno, just habit I guess.
