Okay, so technically this is Day 5 (I'm two days behind the other guys). But for consistency's sake, I'll just fudge the data a little bit and call it day 7, at the risk of looking relatively less manly.
This week's Great Darwin Beard Challenge update is hosted by Kevin Zelnio of Deep-Sea News.
Just to remind you:
"As some of you may know, Andrew, the Southern Fried Scientist, and Kevin Zelnio of The Other 95% and Deep Sea News have begun a Darwinian celebratory challenge of manly proportions. Between February 12th (Darwin’s 200th birthday) and October 1st (The 150th anniversary of the publication of The Origin of Species, according to the first edition cover) they will be evolving from relatively smooth-skinned baby-faced boys to hirsute woolly men in The Great Darwin Beard Challenge."
At least two Davids have joined in the competition as well.

Quote DSN: "Top Right - sexiest deep sea biologist, Kevin Z; Top Left - second sexiest deep sea biologist, Souther Fried Scientist; Bottom Left - just another sexy PhD candidate in deep sea biology, David; Bottom Right - not a deep sea biologist, but sexy nonetheless, Irradiatus from Biochemical Soul. Insets are from T=0." Personally I find my self esteem slightly lower when my face is placed next to these dudes.
Reminder:
"Now, as a normally bearded man, I would love to say that I’m gonna make it through this thing. However, my local environment will most likely soon be invaded by the new selective pressures of interviews and job talks (not to mention the already constant sexual selection pressures from my wife to maintain no upper lip hair). As such, I will most likely have to represent an extinction event in this Darwinian challenge. But I will continue for as long as possible."
