small edits to Blog in response to recent questions

Hi folks,

In response to blogged questions, I added definitions for clinal variation and directional selection to the main posting for this week. And in response to another question, I pasted reference info and a condensed abstract for Pilbeam & Gould, 1974 (mentioned in one of our readings) just below the last definition for the week.

Feel free to ask me if either definition is unclear or for a graphical explanation. See you in class.
