Nice to hear that @mwitte7612 has confirmed the original phylogenetic underpinnings of punctuated equilibria! ~50 years ago today, the song we began to play....@Trilolight @deeptime @jdegregori1 #trilobites . Below, Eldredgeops rana s.s., Moscow Fm., central NYS.

[Matthew Witte, PhD @mwitte7612]

After 8 years of trying to understand the taxonomy of Edredgeops/Phacops rana, it was so cathartic to write this paragraph.

@niles_eldredge, I’ve got excellent news! There’s strong phylogenetic support to confirm Eldredgeops as a genus!

Thank you, Barack Obama —your ideals, wisdom and talents have prevailed after the despicable backlash has finally run its course!

[Barack Obama @BarackObama]

Tonight, the American people sent a clear message — they want a politics that brings people together rather than divides them, and leaders who offer concrete solutions to the challenges they face.

These results were only possible because outstanding candidates stepped forward in every region of the country — including in areas once considered long shots. They came from different backgrounds and represented a range of political perspectives, but were united by shared values, a belief in public service, and a commitment to putting the people of their districts and states first.

We also owe a debt of gratitude to the thousands of election officials and volunteers from both parties who helped ensure a smooth election and carried out one of the most essential functions of our democracy.

While this administration has another two years in office, our job now is to roll up our sleeves, make changes wherever we have the power to do so, prevent further damage, and lay the groundwork for the future.

@JoJoFromJerz Yes!!!

Beautiful!

@AndrejSpiridon4 @niles_eldredge @PalaeoPhilo @CoelhoPre Thank you, Andrej

Out from under the despicable regime!! What a wonderful feeling!!! Congratulations to the American people—all of us!

@StevenErlanger A natural system’s view sees the collapse of the centrist Europe is not in any way its fault.

What’s emerging on Earth is the 5th grand collapse of human civilizations in a row, dedicated to sustaining exponentially growing (regularly doubling) power over nature, with a genuinely suicidal use of compound investment.

I’ve studied it for 40 years with a surprisingly successful scientific method, just following the growth curves, pointing squarely to what’s happening. “Happening” is a burst of emerging system formation, that initiates its life-cycle, opening the door finding where it’s headed, i.e. real science for a subject that formulaic science has avoided like the plague!

@LaVjosa Life saving images… yet ��� the driving use of AI is still for our ever faster growing interference with nature for **profit ignoring the costs** is also unarguably suicidal, continuing our mad world grow to collapse habit — destroyer all our predecessor civilizations!

This is going to become a pressing question sooner than most think.

[Prof. Eliot Jacobson @EliotJacobson]

As the reflectivity (albedo) of Earth continues to set new record lows, more of the incoming solar radiation is absorbed by the Earth system, increasing the amount of energy available to heat the oceans, atmosphere, and land, and to melt ice.

[GO GREEN @ECOWARRIORSS]

This is the end game
Earth's energy imbalance
The difference between amount of energy Earth receives from the sun and amount it radiates outward into space
has more than doubled over past 2 decades, massively exceeding increase predicted by climate models.

How are extinction, evolution and time related? Come to our new conversation hosted by @museuciencies with @AMNH Niles Eldredge and @mncn_csic Susanna Manrubia. From Darwin's reflections, deep time and the fossil record to cancer, network science & pandemics. @niles_eldredge

[Niles Eldredge @niles_eldredge]

@JLydiaHenshaw We are speaking of a sort of meta-epistemological issue of discipline territoriality. I don’t understand your allusion to numerical characterization of adaptive systems—so I guess we are two ships passing in the night here?

[Niles Eldredge @niles_eldredge]

First thing that comes to mind is, when it came to publishing interpretation of my trilobite data in the context of allopatric speciation, I chose the journal Evolution-where it understandably fell on deaf ears as most of its readership were genetically inclined neontologists.

[Andrej Spiridonov @AndrejSpiridon4]

"What we really mean is ‘‘antedisciplinary’’ science—the science that precedes the organization of new disciplines, the Wild West frontier stage that comes before the law arrives..."
So, how was the feeling @niles_eldredge when the paleobiology was an antedisciplinary science?

[Niles Eldredge @niles_eldredge]

@tomdabassman @skdh No she doesn’t . Capitalism is arguably the most efficient of systems in extraction and exploitation of natural resources, thereby merely the worst of many such monetary systems in terms of disastrous negative effects on global physical and biotic environmental components.

[Niles Eldredge @niles_eldredge]

Interesting James: I actually opposed the founding of a separate journal “Paleobiology” in the hopes that “Evolution” and “Systematic Zoology” etc would prove hospitable and we should avoid further fragmentation. Back then ‘twas not to be and I was glad Tom Schopf prevailed.

[James Albert 🐟 🇺🇦 @JamesAl0410008]

For Niles: I classified all 210 papers in the last 10 issues of Evolution (Dec 2025 to Sep 2026).

Microevolution: 43%
Speciation: 24%
Macroevolution: 32%

Only 4 papers (2%) are primarily based on fossils.
