Study of 1,700 languages reveals surprising hidden patterns
Languages may seem wildly different, but new research shows they follow surprisingly consistent—and deeply human—rules.
Science News, Max Planck Society (4/5/26)
Summary
A massive new analysis of over 1,700 languages shows that some long-debated “universal” grammar rules are actually real. By using cutting-edge evolutionary methods, researchers found that languages tend to evolve in predictable ways rather than randomly. Key patterns—like word order and grammatical structure—keep reappearing across the globe. The results suggest shared human thinking and communication pressures shape how all languages develop.
The evolution of a word-order universal on the global language tree. In our analysis of the universal1 “With overwhelmingly greater than chance frequency, languages with normal subject–object–verb order are postpositional”, the absence or presence of the two features defines the ‘state’: state 11 (red) is the prediction made by the universal; in state 00 (black), both features are absent; in states 01 (orange) and 10 (light blue), one feature is absent and the other is present. The ancestral state reconstruction shows that in multiple language families and areas, pathways of language change repeatedly lead to the predicted outcome. Credit: © Verkerk et al.

One might wonder whether the convergence is driven by something(s) external to any given language. Universal systems of math, logic? Wider spread of scientific method, recognition of cause-and-effect? Growth of travel and advances in communication? Methods of storing, conveying, and analyzing information?

The blank spaces in the circle illustration above resembles a wind pinwheel, not to base any conclusion on that.

Not a pinwheel at all! The resemblance is to the descending Holy Ghost in the form of a white dove, suggesting that language is divinely inspired. Also that He's not brilliantly consistent at inspiration.

Hmm. Humans have been speaking Languages for 100,000 years, as a very conservative estimate. We have longitudinal evidence for only a handful of languages over barely a few thousand years. That's inadequate for claiming "tend to evolve"/"universal" anything.
There's some evidence constituent order can 'flip' over time. (PIE is thought to have been SOV, although that's been disputed — previously on LLog.) Perhaps these things go in cycles, and the invention of writing/dominance of global English has frozen at a more-or-less random position?

Word order can absolutely change over time. Latin had a default of SOV, with practically any rearrangement possible (and many of them common) for emphasis or poetry; the Romance languages today are pretty strictly SVO (but SOV within the verb complex). Within Old High German you can watch the modern finite-verb-second and finite-verb-last orders emerge over a few hundred years. Welsh changed from default VSO to default SVO and back to default VSO across a thousand years or less (throughout with rearrangements for emphasis possible). Modern Mandarin is pretty strictly Topic-Verb-Focus, but Classical Chinese has a lot of Topic-Focus-Verb default. And so on.
