There is no missing link.

Its just a line of fosills from A..B...C......H..I...N...V...X..YZ, and whenever there is a fossil discovered to be - say - put in between I and N you have 2 new "gaps".
Which in turn get popularized as "the (new) missing link".

Yes the fossil record is not complete (that would require a unbroken chain from FossilA to FossilZ - an by its nature fossilised stuff is rare (enough) to not be complealty avaliable).

# I'm no expert - and the missing link stuff via media is getting to me - so here is my layman clarification. Also the Letters A-Z have only illustrative purposes here. #

wow thats .... unhelpful

I bought a Brother 5250 with network and tumble (print on both sides of a page).
Works flawlessly with Linux/OSX/Win.

Though I know of an Kyocera BW Laser bought ~ 1990 which still works fine as long as you don't bust its RAM by printing images.

Darn, hitting options->save while editing on ./ ate my msg, so I just say:

Yes, also comments need maintenance as well as code does. Guess which is more up to date.

I couldn't read this comment without thinking of the lg Nobel Prize Math Category Winners from 2008 and their work.
enjoy
