That's because early branching does not equal ancestral. Basic tree thinking. Very often misunderstood, though, including in the scientific literature.

Another day, another NSF announcement about funding AI instead of science.
Lenny from the Simpsons replacing a sign saying "0" with another sign that also says "0" as a part of a larger sign that reads, "0 days without email from NSF about AI". implicit here is that the meme author wished to say "fucking AI" but the text became too small and also I'm not sure NSF is funding people to literally fuck AI, but who even knows anymore.

To be clear: what I object to is not funding STEM (I'm pro-STEM!) nor do I even object to a relative funding differential between STEM and the humanities. What I object to is that many research universities do not provide basic infrastructural research and teaching support to humanities disciplines.

The iconic Ediacaran fossil Dickinsonia from the Central Urals onlinelibrary.wiley.com/doi/10.1002/... #PapersinPalaeontology @datadryad.bsky.social
Main photograph is of fossil Dickinsonia densa from the Konovalovka Member of the Cherny Kamen Formation of the Sylvitsa Group, Central Urals (paratype, GEOCHRON 2057-296). An oval, striped organism, the same colours as the surrounding matrix. Long white scale bar at lower right is 10 mm.
On the right, a vertical set of diagrams showing a schematic model of Dickinsonia preservation in the Konovalovka Member. At the top, the specimen rests on a clay-rich substrate during life. Moving down, it is rapidly buried by an overlying sand layer and pyrite (Fe2S) forms around the decaying body due to microbial activity. Later partial erosion of the sand layer occurs, and finally, the organism is buried by alternating clay and sand layers.
Red rectangle in lower left corner is a cover image from the journal Papers in Palaeontology.
