Mammuthus,
I also think Lamarck is regarded as a great scientist. When I said that he was often not given his due, it was mostly in reference to the fact that a great many creationist pieces of literature attempt to discredit him almost completely because of his beliefs concerning pangenesis. As a creationist myself, I try very hard to not fall into these traps also. I dont feel one gains much by attempting to destroy the image of an intelligent man. Granted, such attacks are also shown in evolutionary literature. That is someone else's problem and so I can only worry about myself.
I breifly skimmed over the Lamarck page you posted a link to. It looked interesting and I will enjoy reading it at a later date.
