Language Evolves In Sudden Leaps, Not Creeps

Languages evolve in sudden leaps, not creeps

Language evolves in sudden leaps, according to a statistical study of three major language groups. The finding challenges the slow-and-steady model held by many linguists and matches evidence that genetic evolution follows a similar path.

Mark Pagel from the University of Reading in the UK and colleagues applied statistical tools commonly used in biology to the analysis of three of the world’s major language groups: Indo-European, Austronesian, and Bantu.

By comparing commonly used words within each language group, they were able to identify the extent to which languages within a group diverged from the others. This enabled them to build a family tree, charting the divergence of one "mother tongue" into hundreds of daughter languages.

If languages change at a constant rate, the length of any branch back to the root of the language "tree" should be of the same length. But the researchers found that languages that are very different from the common root had longer paths. This suggests that, each time they split, an abrupt spurt of evolution occurs.

They found that up to a third of all vocabulary changes result from "punctuational bursts of change" when one language splits from another.

In 2005, Pagel performed a similar analysis of genetic variation in species of trees. He found that 22% of evolutionary change came during similar periods of rapid development in some species. "In one case its words, in the other case its genes," Pagel says.

Pagel says languages may diverge suddenly when a subgroup separates from a larger population, to create a unique social identity. Similarly, genetic change may occur suddenly as genes try to adapt quickly to a new environment.

The English language has taken a nose dive so the article makes sense what with all the breeding going on.

Probably has something to do with migration and war.

Nonsense. The language that the Brits speak evolved very gradually from whatever the Celts spoke to what BBC announcers use now. The romans, saxons, vikings, and normans who moved in and set up shop over the years had nothing to do with it.

This fits with Stephen Jay Gould’s theory of punctuated equilibrium.

I sure did develop different speach patterns shortly after joining the military! JHC, some of that was so FUBAR that one would want to go AWOL. Know what I mean?
