All users may post questions about MCAT, DAT, OAT, or PCAT organismal biology (anatomy, physiology, development, embryology, and evolution) here. Cellular bio, molecular bio, and biochemistry questions should be posted in the other biology thread. We will answer the questions as soon as we reasonably can. If you would like to know what biology topics appear on the MCAT, you should check the MCAT Student Manual (http://www.aamc.org/students/mcat/studentmanual/start.htm)

Acceptable topics:
-general, MCAT-level biology.
-particular MCAT-level biology problems, whether your own or from study material
-what you need to know about biology for the MCAT
-how best to approach to MCAT biology passages
-how best to study MCAT biology
-how best to tackle the MCAT biological sciences section

Unacceptable topics:
-actual MCAT questions or passages, or close paraphrasings thereof
-anything you know to be beyond the scope of the MCAT

If you really know your organismal biology, I can use your help. If you are willing to help answer questions on this thread, please let me know. Here are the current members of the Organismal Biology Team:

Maddscientist (thread moderator): Maddscientist is a Ph.D. student in developmental biology.

TheDarkSide: TheDarkSide has several years of experience working as a nurse. She scored 12 on the BS portion of the MCAT, and 37 overall.

Occasional moderator: Shrike. Shrike is a full-time instructor for The Princeton Review. His primary expertise is in other subjects; he knows just enough biology to have scored 12 on the BS section without ever having studied organic chemistry.
