user69: When looking at the learning tag, three questions are regarding the learning of biology as a science whereas one is using learning in the ethology sense.  Clearly these two should be split up but which tag should take preference - self learning the field of biology or learning in a biological sense?

user6: Using learning for questions about resources for learning is pretty much using it as a meta tag. That is discouraged on all SE sites. There is not much use for such a tag, it is far better to tag those questions with the specific topic they are about, e.g. cell-biology. 
I removed all those instances of the tag and replaced them with something more useful.
