You asked and I told you, nothing more nothing less. Your trying to argue with no point. The pattern on it is a barbwire back spider. A spider is a spider is a spider. There has been no proven line to a spider besides spider. Now patterns tend to be different like you have here. Most people refer to a spider with the pattern of your as a "black back" or "barbwire" spider, if you like or not that is what it is.
I'm perfectly fine, your arguing for no reason. Why ask a question if you don't like the answer.
And as for your NERD reference, they haven't proven it to genetic so I don't have to tell them they are wrong, seeing they never said it to be genetic. There is no genetic line of a reduced pattern animal. Now in a sense it is "genetic" because it has to do with genes but that's about it. A normal spider can throw a reduced pattern or a barbwire spider.
