| Paleontologists debunk fossil thought to be missing link between lizards and first snakes Posted: 18 Nov 2021 03:16 AM PST Filling in the links of the evolutionary chain with a fossil record of a 'snake with four legs' connecting lizards and early snakes would be a dream come true for paleontologists. But a specimen formerly thought to fit the bill is not the missing piece of the puzzle, according to a new study. |
| 'Volcanic winter' likely contributed to ecological catastrophe 250 million years ago Posted: 17 Nov 2021 01:14 PM PST A team of scientists has identified an additional force that likely contributed to a mass extinction event 250 million years ago. Its analysis of minerals in southern China indicate that volcano eruptions produced a 'volcanic winter' that drastically lowered earth's temperatures -- a change that added to the environmental effects resulting from other phenomena at the time. |
| Perceptual links between sound and shape may unlock origins of spoken words Posted: 17 Nov 2021 07:01 AM PST Most people around the world agree that the made-up word 'bouba' sounds round in shape, and the made-up word 'kiki' sounds pointy -- a discovery that may help to explain how spoken languages develop, according to a new study. Language scientists have discovered that this effect exists independently of the language that a person speaks or the writing system that they use, and it could be a clue to the origins of spoken words. |
