Evolving a bigger brain with human DNA
The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger ...
Probing the deep history of human genes and language
Brown University evolutionary biologist Sohini Ramachandran has joined with colleagues in publishing a sweeping analysis of genetic and linguistic patterns across the world's populations. Among the findings ...
The ABC's of animal speech: Not so random after all
The calls of many animals, from whales to wolves, might contain more language-like structure than previously thought, according to study that raises new questions about the evolutionary origins of human language.
Study reveals a way to improve chances of winning at rock-paper-scissors
Primate calls, like human speech, can help infants form categories
Human infants' responses to the vocalizations of non-human primates shed light on the developmental origin of a crucial link between human language and core cognitive capacities, a new study reports.
Language structure arises from balance of clear and effective communication
When learning a new language, we automatically organize words into sentences that will be both clearly understood and efficient (quick) to communicate. That's the finding of a new study reported today in the Proceedings of ...
Language driven by culture, not biology
After merger, chimpanzees learned new grunt for 'apple'
Chimpanzees have special grunts for particular types of foods, and their fellow chimps know exactly what those calls mean. Now, by studying what happened after two separate groups of adult chimpanzees moved in together at ...
Features of language show a strong link to the geographic dispersal of human populations
Geneticists have famously tracked small differences in the human genetic code to trace the evolution and spread of humans out of Africa. Languages can change more quickly than genes and are not necessarily ...
Orangutans crack consonants and vowels to shed new light on the evolution of human speech
Scientist still dont know how human speech evolved from our great ape ancestors. But a study involving Liverpool John Moores University (LJMU) and the Pongo Foundation has uncovered new calls from orang-utans ...
Humans, sparrows make sense of sounds in similar ways
The song of the swamp sparrow—a grey-breasted bird found in wetlands throughout much of North America—is a simple melodious trill, repeated over and over again.
Fruit flies help scientists uncover genes responsible for human communication
The evolution of language in humans continues to perplex scientists and linguists who study how humans learn to communicate. Considered by some as "operant learning," this multi-tiered trait involves many ...
Zebra finches are sensitive to emotional cues in human speech
A study in Proceedings of the Royal Society B shows that zebra finches can pick up on the features in human language that express emphasis and emotion.
Microbes provide insights into evolution of human language
Big brains do not explain why only humans use sophisticated language, according to researchers who have discovered that even a species of pond life communicates by similar methods.
