The Paradigms They Are A-Shifting

Here’s a collection of science news about
long-held paradigms that were wrong.
But can we trust the new shifts?

There’s a lesson in the following stories: what science says today can be wrong tomorrow. The items are from different branches of science to show that overconfidence in consensus touches almost all areas of human thought. Lesson: When you hear them say, “Now we know,” hold on to your skepticism.

Mars’ ‘young’ volcanoes prove more complex than scientists once thought (The Gist, Geological Society of America, 11 Feb 2026). It wasn’t a single eruption. It’s complicated. Magma moves. It evolves.

Rethinking climate change: Natural variability, solar forcing, model uncertainties, and policy implications (Phys.org, 11 Feb 2026). If what Nicolas Scafetta claims in this “rethink” article is closer to the truth than the consensus on climate change, it could upset a global applecart. He’s discounting the human-caused role and criticizing measurements, claiming that “global climate models still fail on natural variability at all scales.” It’s amazing he hasn’t been canceled yet, or called a “science denier.” His thoughts are pre-published in the April 2026 issue of Gondwawa Research, and he is a geoscientist at the University of Naples.

Deep-sea fish larvae rewrite the rules of how eyes can be built (The Conversation, 11 Feb 2026). Visual receptors in the retina used to be neatly divided into rods and cones. Studies of deep sea fish showed that science needs to add “rod-like cones” to the mix. Several genera adapt to the darkness of the deep in larval stages with these hybrid receptors. The authors point out, by the way, that most of the monstrous, creepy denizens of the deep with big eyes and threatening teeth are small: about hand-size or thumb-size.

Europe’s “untouched” wilderness was shaped by Neanderthals and hunter-gatherers (Aarhus University via Science Daily, 11 Feb 2026). Other paradigms about Neanderthals are also shifting this month toward personhood: “Neanderthals and early humans may have interbred over a vast area” (New Scientist, 2 Feb)—i.e., they were fully human. “Neanderthals took reusable toolkits with them on high-altitude treks through the Alps” (Phys.org, 21 Jan)—i.e., they were smart, strong, and inventive.

‘Textbooks will need to be updated’: Jupiter is smaller and flatter than we thought, Juno spacecraft reveals (Live Science, 4 Feb 2026). Some revisions and updates can be forgiven when better data becomes available, but the science of measurement is sometimes not as clear-cut as we are led to believe.

“Textbooks will need to be updated,” study co-author Yohai Kaspi, a planetary scientist at the Weizmann Institute of Science in Israel, said in a statement. “The size of Jupiter hasn’t changed, of course, but the way we measure it has.“

The new value will have implications for theories and models, and even worldviews. “This research helps us understand how planets form and evolve,” Kaspi said. Where have we heard about things “forming and evolving” elsewhere? Oh yes: everywhere. Please, Dr Kaspi, tell the world when the understanding arrives.

Yellowstone wolves may not have transformed the national park after all (Utah State University via Science Daily, 12 Feb 2026). One of the biggest justifications for returning wolves to Yellowstone was ecological: it would return the landscape to its pre-human balance of predators and prey, and that would be reflected in the plant life. Whoops:

A new scientific review challenges the headline-grabbing claim that Yellowstone’s returning wolves triggered one of the strongest trophic cascades on Earth. Researchers found that the reported 1,500% surge in willow growth was based on circular calculations and questionable comparisons. After correcting for modeling and sampling flaws, the supposed ecosystem-wide boom largely disappears.

This strange little dinosaur is forcing a rethink of evolution (Vrije University Brussels via Science Daily, 3 Feb 2026). The first paragraph shakes things up:

A newly identified tiny dinosaur, Foskeia pelendonum, is shaking up long-held ideas about how plant-eating dinosaurs evolved. Though fully grown adults were remarkably small and lightweight, their anatomy was anything but simple—featuring a bizarre, highly specialized skull and unexpected evolutionary traits. Detailed bone studies show these dinosaurs matured quickly with bird- or mammal-like metabolism, while their teeth and posture hint at fast, agile lives in dense forests.

Maybe they were just traits and not evolutionary traits. Think about that. That’s how you “force a rethink of evolution.”

This brain discovery is forcing scientists to rethink how memory works (Univ of Nottingham via Science Daily, 3 Feb 2026). Score one for the lumpers against the splitters. “A new brain imaging study reveals that remembering facts and recalling life events activate nearly identical brain networks. Researchers expected clear differences but instead found strong overlap across memory types.”

Enormous ‘mega-blob’ under Hawaii is solid rock and iron, not gooey — and it may fuel a hotspot (Live Science, 2 Feb 2026). Professor Doyeon Kim was correct part of the time, like when he said, “We have to first clearly understand what’s happening on Earth to understand fully what’s happening on other planets.” What does that imply?

Hafted stone tools in China suggest early hominins were more inventive than thought (Griffith University via Phys.org, 27 Jan 2026). Weren’t evolving hominins supposed to be primitive 160,000 years ago? And how did they get to China way back then? Curious, very curious (if you accept the evolutionary narrative and timeline).

Ancient humans were seafaring far earlier than we realised (New Scientist, 28 Jan 2026). Michael Marshall has misjudged ancient humans so many times, he should consider a career change, or else ditch the evolutionary timeline.

Thousands of years before the invention of compasses or sails, prehistoric peoples crossed oceans to reach remote lands like Malta and Australia. Doing so meant striking out in unknowable conditions. What do such crossings tell us about ancient minds?

Answer: they weren’t evolving. Mike, you can cut the royal “we” out of your writing.

Sea turtles may be more resilient to global warming than we thought (New Scientist, 23 Jan 2026). Writing in Tontological format, Chris Simms tries to sweep us into his “royal we” pronoun. If you didn’t think this, don’t let him get away with it.

Humans returned to British Isles earlier than previously thought at the end of the last ice age (The Conversation, 21 Jan 2026). “The return of humans to the British Isles after the end of the last ice sheet, which covered much of the northern hemisphere, happened around 15,200 years ago,” Adrian Palmer (University of London) says, “– nearly 500 years earlier than previous estimates.” That’s not a huge rethink, but a rethink nonetheless.

I have to stop or this list could be multiplied, but specific examples help emphasize the point: science is tentative, not absolute. In our 25 years of reporting, we have seen many paradigms shifted and accepted ideas overturned, some of them truly monumental. This is understandable to a point, because human beings are finite and subject to various biases and influences. If scientists would ditch evolution and the evolutionary timeline, though, I suspect a sizeable percentage of such revisions would evaporate.
