Have you seen this one? U 1125 at Krogsta.

But it is at least striking and indisputable that it is precisely in Western Europe where we think mostly of the church and its influence that modern science emerged and so vigorously developed. Correlation is not causation but the counterfactual, that the church inhibited it would be hard to show.

The “church” considered broadly as an institution has existed for a long time and in many places and it is hard to draw completely comprehensive conclusions. Byzantium for example isn’t normally associated with significant scientific advances (but see people like Philoponus who influenced Galileo).

Of course the scientific revolution made immense advances. But these advances were in many cases built on or at least partly anticipated by earlier work. The idea of dividing human history into watertight “periods” such as the dark ages or scientific revolution has long been abandoned by historians.

In many cases it was the church structures themselves that enabled technological advance. One example is the development of blast furnaces and metallurgy by the Cistercians (see eg

en.m.wikipedia.org/wiki/Laskill ) and arguably it was the Reformation that put a stop to such inventiveness.

The height of the power of the medieval papacy was between say 1100-1300 peaking with Innocent III at 1198-1216. But that corresponds to the “high Middle Ages” which saw great advances in all sorts of ways in Western Europe including in science and technology.

When do you think that period was?

Last time I visited you had to get the key from a shop down the road is that still true??

Main findings: clades very imbalanced; large clades likely to have emerged at time of high tempo and then slowed; expected amount of molecular change on each branch equal (so no molecular clock in this model) and large diverse clades expected to be accompanied by small, conservative “living fossils”

Our covariant model of evolution is now out in @systbiol.bsky.social. In it, rates of diversification and molecular and morphological evolution all covary governed by a “tempo” variable which itself also varies at a rate equal to its own value. @richardpmann.bsky.social doi.org/10.1093/sysb...
Evolutionary Tempo, Supertaxa, and Living Fossils
Abstract. A relationship between the rate of molecular change and diversification has long been discussed, on both theoretical and empirical grounds. Howev

We are looking for new colleagues to come join us in Galway as group leaders (Junior and Senior). The Centre for Chromosome Biology is a great place and it is a good time to join. Please reach out if you want to chat about the opportunity!

Here is our attempt at summarizing the state of the evidence for the punctuated equilibrium hypothesis. The paper is part of a special issue of Paleobiology celebrating the 50th anniversary of the PE Hypothesis. Work led by Gene Hunt. @lhliow.bsky.social www.cambridge.org/core/journal...

It's publication day of my first book: The Tree of Life. The tree of life is a time machine that can take us back 4 billion years to meet our most distant ancestor. It is the magic that lets us tell the origin stories, beginning with this ancient relative, of everything from mushrooms to man.
