[ECOLOG-L] correlation v. causation

[Shelly Thomas]

Dear Colleagues,The gen ed program and science departments at my university are 
having a conversation this week about correlation v. causation.  Already I am 
finding serious differences (even within specific disciplines) in how one 
determines "causation."
What do you think is required for causation (and what field are you in)?
Thank you,Shelly
