Scientists are calling for more evidence that culture influenced human evolution, arguing that its influence extends to human language.
In an open letter to the editor in the journal Science, the group of scholars who authored the study say they have found more evidence for the hypothesis that humans evolved by using languages.
“In the past 50 years, we have seen significant advances in understanding the evolutionary origins of language and cognition,” the scientists wrote.
“The study is the first to examine how cultural influences may have been involved in the origin of human language and cognitive abilities, and to consider how these cultural influences might be transmitted across populations.”
The scientists also say they want to know more about how culture and language evolved independently and independently, rather than from one another.
The group includes a number of leading scholars, including University of California, Berkeley’s Michael Behe, and the University of Southern California’s James Clark, who also wrote the paper.
Their conclusion is that “the evidence for an ancient origin of language does not support the view that the emergence of language as a tool of culture is a novel phenomenon.”
The study comes after a group of researchers announced in October that they had published a paper that suggested that some people have a genetic predisposition to learn a language in the first place.
The researchers said the findings support the idea that “human evolution was the result of cultural processes.”
A new study released last month also supports the hypothesis, with the authors finding that certain people are more likely to acquire language than others.
However, the researchers also note that their findings do not prove that language was the primary driver of human evolution.
The authors note that, while there is strong evidence for language as an evolutionary mechanism, it is still too early to say whether language played a key role in human development.
In addition to the new study, a number other recent studies have found strong evidence that cultural influences play a role in the development of language, including a study of people from various cultures that found that some had a stronger propensity to learn to speak a language if they had been raised in an environment that supported it.
The scientists said that in some cases, the same environment might have had a positive effect on language, while in other cases it might have played a negative role.
