Micro-evolutionary bursts of change

Mmm-mmm, delicious geeky t-shirt designs, I can’t get enough of them. This one recently caught my eye over on ThinkGeek:

Here’s the description:

Sure, Darwin noticed the gradation in beak size of his “finches” in the Galápagos Islands, but he missed some big differences. For instance, we could have had significantly more 19th century science fiction if he’d noticed the Vampire Finch (Geospiza difficilis septentrionalis), which feeds on the blood of other birds. Our own team of ThinkGeek Junior Ornithological Knowledge Explorers has, consulting the excellent research conducted by Drs. Marvel and DeeCee, discovered six new variations also evolving from the Tiaris obscura:

• a. super intelligence (for outsmarting Darwin)
• b. super beak (for eating stale bread crusts tossed by tourists)
• c. super eyes (for seeing through the garua)
• d. super limbs (for outmaneuvering the Vampire Finch)
• e. super speed (for visiting friends on the mainland)
• f. super squawk (for broadcasting the latest volcanic activity)

Jeremy Kalgreen is on a designing spree at the moment and has churned out some wonderful t-shirts in the last few weeks, but this one is my favourite of the bunch – Xenu Airlines:

It’s a stab at Scientology, if you hadn’t realised. You’ve just got to love those Teach the Controversy designs…
