So how does a partial evolution of a complex system benefit the species? That is all I am asking. How does a gland that secretes a poison of any use if there is not duct to carry it to where it is useful? The example applies to ANY complex, inter-related system. Its "magic talk" to expect that "someday we will understand". Its a very basic part of the theory, and I fail to see how it works, even at my, most basic level, of comprehension.
