I have an evolution midterm in a couple hours. Doing some last minute studying. I had to look up some important scientist involved in evolution....Don't have first names...Does anyone have any clue who Gray is? Who is...last name Asa? I was able to find out about Wallace, Lyell, Lamarck and Dobzansky but I don't know who the other two are...HELP!!! this might come on the exam!
