Hey,

Since the Tree of Life by Denny is outdated, we thought it was a nice idea, to have a new one, to have an overview over the biological taxonomy on wikidata. Not only to have a nice looking tree but also to see, where errors are and to correct and update it.  Right now, there are 660775 Items in the tree. 
Even though the change of names can be seen instantly, because this is based on the API, changes in the order need an update of the whole tree, because it's based on wikidata dumps. (This one on the most recent one from 15.12.2014)

Here you go, this is the new tree of life, made with a lot of love: https://tools.wmflabs.org/tree-of-life/

If you have any corrections, additions or features you want to add, feel free to ping me, send me a mail, submit a patch or file an issue on github. The repo for the tree is on https://github.com/frimelle/tree-of-life
