I've got houseguests visiting currently, which, combined with some work that needs doing, means that I won't have much time to post. So, to help you, my dear reader, get through this tough time, I've assembled a few biology links for you to peruse.
Here are a few from PZ Myers:
The evolution of deuterostome gastrulation - the title sums it up.
Ancient rules for Bilaterian development - looks at the evolutionary roots of bilateral symmetry in animals, focusing on sea anemones (which are generally radially symmetrical).
Generic bumps and recycled genetic cascades - looks at similarities in gene expression during the development of genital structures and limbs.
Flap those gills and fly! - posits that insect wings evolved from crustacean epipod gills.
And here are a few from Orac:
Creationists muscling in on my territory - a post looking at the control of blood vessel growth in the human eye.
Overcoming difficulties reporting science - a post looking at science reporting from the perspective of science reporters.
And, of course, don't forget his recent series on alternative treatments.
