PURPOSE: To show that "Filter by taxonomy" cannot deal with more than one taxon.

Here I show that a union between milkweed butterflies and dung beetles is impossible.

I hope, however, that I am doing something wrong. I have tonight thought of quite a couple cool ideas for Projects that will require this functionality.

One quick example: Making proposed Project Water Bugs tag-driven on the existing tag 'waterbugs' requires a lot of cooperation from people who do not even know of the possibility, let alone of using this tag. That requires a clutter of comments, not necessarily understood by the contributor or in fact heeded to. An alternative tagging procedure is for the Curator to be on the tips of his toes and add the required tag to all candidate observations. That is ... if the southern African Curator is eventually given back this essential capability. But even so, and besides it being a lot of doff work, that would require from the Curator to know and recognise each observation as a water bug (or whatever else).

To make a Project of, say, water bugs, or water beetles, or water plants, etc., requires the erection of a functional group that is not a phylogenetically monophyletic group. There are a gazillion of ecological/functional topics for which such a Project will be welcome. All of them require the combination (logical union) of more than one taxon. Unfortunately it seems to be impossible. Not being a computer programmer, admittedly, I do not imagine that the implementation of such functionality would require a degree in rocket surgery.

Please, Team, may we have this functionality? The possibility to have more than one taxon in "Filter by taxonomy"?

I shall remove this demonstration as soon as somebody gets sick of it. If the Team grants this filter functionality, I may retain this Project as Proof of Principle.
