Is Systems Biology valid science?

@Timothy_Horton

How can you judge evolutionary biology to have a “substantial speculative component” when you’ve never read or studied anything on the subject and have demonstrated zero knowledge or understanding of the science involved?

That’s not my personal opinion. As you well stated, my lack of knowledge disqualifies me from judging anything in this field. However, I see it in some papers I read. For example, see the last paragraph quoted in the second post here.
