is a fun (still WIP) website for biology/phylogenetics nerds. The stated purpose is to showcase lots and lots of examples of convergent evolution, but most of these I didn't know even one example of, and concepts are covered in good detail beyond the convergence part.
The pages that don't exist yet are neat jumping-off points for looking up stuff elsewhere, like:
"Tool use in elephants ...
Elephants are well known for their accuracy in throwing objects, and in addition use sticks for a number of purposes. Also of considerable interest is their use of fly-whisks to keep blood-sucking flies at bay."
I didn't know that...
