I’ve written something for The Conversation on a fascinating recent paper by @grahbudd.bsky.social and @richardpmann.bsky.social on problems with molecular clocks. academic.oup.com/sysbio/artic... theconversation.com/a-speeding-c...

A speeding clock could solve Darwin’s mystery of gaps in animal fossil records
Scientists have long been confused about ‘missing’ animal fossils.

@rcply.bsky.social argues that phylogenetic inferences in sponge–ctenophore–bilaterian relationships based on shared chromosomal rearrangements suffer from insufficient statistical support. 🔗 doi.org/10.1093/molbev/msaf321 #evobio #molbio

Do diversification rates and molecular evolution covary? Maybe, maybe not, but it’s surprising how much falls into place if we assume they do doi.org/10.1093/sysb...

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...

New entry into the sponge/ctenophore debate.... Have the chromosome fusions separating ctenophores from all other animals been given too much weight? Beautifully clearly written paper covering complex arguments from @rcply.bsky.social. www.biorxiv.org/content/10.1...

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.

I am seriously becoming of the opinion that there should be a (ideally permanent, but at least a few years) moratorium on publication of molecular clock papers. This would allow authors to reflect on the idea that their results invariably involve “event x happened 10s - 100s Myrs before we thought”.
