Darwinism Cannot Explain The Peacock

Bias is essentially non-existent in science, thanks to peer-review. Also, you have not addressed the idea of the tail helping the peacock in the past, and it is a vestigal structure that is (if my theory prevails) slowly losing its luster. Also, it is impossible to tell what the peahens desire. Simplifying it to "length, color, symmetry" is far to simplistic. For example, they may see more colors than we, or perhaps go for certain designs, or perhaps it is a combination of if the male has the right stuff and struts it well enough.
