Quick question (or am I going crazy?):

I am preparing my lecture on "simple" animals and lophotrochozoans tomorrow and noticed our textbook places the pterobranchs right in the middle of the protostomes!!! Have I missed something? Has there been a change in how we view pterobranchs -- was there a new study that showed they were really not deuterostomes?

Just thought somebody out there might help me here -- I swore they were hemichordates! Please answer me off-list ... and I apologize for this not being a dino-related post ... although it is chordata ... sort of. =)

Thanks in advance,
