Tolweb has retired
The Tree of Life Web Project has been retired as an actively growing site. We are currently working to preserve the existing content; until this transition has been completed, the project will be unavailable until it is properly archived.
A message from David Maddison
The Tree of Life Web Project began its journey almost 40 years ago, and was formally announced in early 1996. It has served thousands of pages of information about the evolutionary tree of life and the characteristics of organisms that evolved along its branches; this content was contributed and curated by hundreds of biologists who were experts in particular branches of life.
I no longer have the resources to keep the project functioning as it has been, and thus it will be retired soon (by the time you read this, it may have been retired). I have hopes that it will be reborn in a more primitive way as a series of static web pages that capture a snapshot of the content it contained when it ended. If so, you should eventually see, at its old web address tolweb.org, a basic version of the content.
