well, not just anatomy, but all the basics to drawing... like perspective.
I mean, forget anatomy and all the complex stuff, if you don't have perspective, your drawings are doomed to fail from the very start. Then comes proportion, in what I think is the second most important (but you need perspective first to get proportion right anyways, hence it being second). Then you can get to anatomy and all other sorts of details.
As to the anatomy part, you can actually sort of cheat and just learn it form other (good) artists (of the style of anthros you like anyways), which is what I did, and I must say, I think that it helped a lot (and interestingly enough learned to draw ferals after, though it was not that hard to do, considering that the style I like is not all that far removed, most of the time; ie, legs are already digitigrade).
Sure, I can't draw human faces, but... who cares. I don't. (Drawing humans was never any interest for me, at all, what-so-ever, period.)
