The Tree of Life web project is back! A phylogenetic view of biodiversity way ahead of its time (ca. 1995!), conceived and led by David Maddison, collaborative & human-curated, widely used in teaching. Defunct technology had doomed it until Travis, Danny, and Andrew revived it. 🥳🎉 🧪 #evolbiol

An old quip: "All stories you read in the newspaper are completely true except those for which you have first-hand information." This has many corollaries, e.g. "All clades are purely diverging, without introgression, except for those for which you have the pertinent data." 🧪 #evolbio

Have any of you played the ZoL adventure game in Mesquite 4.02? (It's pretty short in its current version.) We'd welcome feedback about it as a game for students learning phylogeny.

Does Mesquite's phylogenetic adventure game look familiar to anyone? 🧪 #evolbio
Screenshot of Mesquite's log window, saying: 
"ZoL: The Great Phylogenetic Adventure!
Level 1

You are standing in an open field.
In front of you, to your surprise, is an organism.
You recognize that it is a Kelp (Ochrophyta).

There is a small mailbox here."

Wayne Maddison @waynemaddison.bsky.social · 28/10/2025
The scoop: To get to Mesquite's adventure game, type "ZoL" into the log window. You will find yourself in an open field with a mailbox. 📬 (If that does nothing, then you'll need to turn on "Use Log Window for Command" under File>Defaults>.)

👀 Mesquite's adventure game has been discovered by @josephwb.bsky.social! BTW, for those of you teaching phylogeny of all life or a particular group of organisms, the adventure game is designed for students to test their knowledge of relationships. (Yes, we'll reveal how to access the game!)

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

The fifth law of thermodynamics is that in a closed system, bureaucracy will always increase over time. There remains the possibility that this is merely a specific instance of the second law, with bureaucracy = entropy.

Leadership from UC Berkeley. "...we see recent actions going beyond those purposes in ways that threaten core values: academic freedom, freedom of inquiry, & freedom of expression.... we will be steadfast and unrelenting in our efforts to defend those core values."
Like many of you, we are gravely concerned about recent Federal government actions in regard to higher education. While we recognize that the government plays an important role in addressing discrimination and ensuring good stewardship of public resources, we see recent actions going beyond those purposes in ways that threaten core values: academic freedom, freedom of inquiry, and freedom of expression. We do not know what demands the Federal government may make of Berkeley, but do know that we will be steadfast and unrelenting in our efforts to defend those core values. A Berkeley without academic freedom, without freedom of inquiry, without freedom of expression is simply not Berkeley.



We recognize that some of you may find our statement too timid or too bold or deficient in some other way. That’s okay—a key to Berkeley’s excellence is our diversity of opinion and perspective. Robust debate is essential to scholarly advance. The purpose of a university is not to present us with ideas with which we are comfortable. To borrow from Clark Kerr, it is to make us safe for ideas.



We don’t know what will happen. In part because we don’t know what may be demanded of us and in part because we won’t be the only decision makers. But what we do know is that we will stand up for Berkeley’s values and defend them to the very best of our ability. For 157 years, through the education it provides and the research it produces, Berkeley has produced immense economic and societal benefit to its students, California, the nation, and the world; this societal jewel needs to be preserved and defended, and we will toil tirelessly to see that it is.  



Fiat Lux.
