The association between maternal genetics and linguistic sounds had not previously been tested worldwide.<\/p>\n<p>\u201cOverall, we found that this phenomenon seems to occur in some\u00a0geographic regions\u00a0but not others, indicating that cultural practices can affect how languages and genes are transmitted, but that it is difficult to make global predictions about these cultural practices,\u201d Creanza said.<\/p>\n<p>\u201cIn particular, matrilineal populations in Africa appear to have a closer association between language and mitochondrial genetic variation than expected.\u201d<\/p>\n<p>To conduct the study, which has been\u00a0published\u00a0in the\u00a0<em>Proceedings of the National Academy of Sciences<\/em>, the research team used genetic, linguistic, and ethnographic data from 130 populations around the world to explore whether language is preferentially transmitted in parallel with maternally or paternally inherited genes.<\/p>\n<p>\u201cAs people move around the globe, they take their genes and languages with them, and both the genes and the languages slowly change,\u201d Creanza said.<\/p>\n<p>\u201cThus, when two populations are further apart, they tend to be more genetically different and have more\u00a0different sounds\u00a0in their languages.<\/p>\n<p>\u201cHowever, males and females do not always follow the same movement patterns\u2014for example, in some populations, wives might move to live near their husband\u2019s family, and in others, husbands might move near their wife\u2019s family.\u201d<\/p>\n<p>Creanza said this study built upon her previous work, which showed that the sounds in languages followed similar geographic patterns as\u00a0genes\u00a0did.<\/p>\n<p>\u201cI hope that it inspires future genetic researchers to more closely consider the cultural, ethnographic, and linguistic features of the populations they study,\u201d she said.<\/p>\n<p>\u201cGenes do not tell the full story of human evolution, and incorporating these cultural considerations is crucial for understanding humans and their history.\u201d<\/p>\n<p>The paper appears in a\u00a0special edition\u00a0of\u00a0<em>PNAS<\/em>\u00a0that highlights 50 years of the quantitative study of cultural evolution, or how learned behaviors change over time, such as human\u00a0cultural practices\u00a0and languages.<\/p>\n<p>Creanza co-edited the special edition, which features a collection of articles on the field of cultural evolution.

In particular, forms of societal organization, including movements in and out of a community, may have shaped the transmission of both genes and languages.<\/p>\n<p>If children were more likely to learn their mother\u2019s language than their father\u2019s when their parents were from populations that spoke different languages or dialects, then language variation might show a closer association with maternally transmitted genetic markers than autosomal ones; this association could be further reinforced if children reside with predominantly maternal kin.<\/p>\n<p>We analyze the worldwide relationship between linguistic and genomic variation, leveraging the sex-biased transmission of X chromosomes to assess whether language has tended to be preferentially transmitted along the male or female line.<\/p>\n<p>In addition, we measure the effects of postmarital residence with female kin, matrilineal descent, and endogamy on the covariation of mitochondrial DNA and languages, using mtDNA because genomic data were available for very few populations with these ethnographic traits.<\/p>\n<p>We find that while there is little evidence for a consistent or widespread sex bias in the transmission of language, such biased transmission may have occurred locally in several parts of the world and might have been influenced by population-level ethnographic characteristics, such as female-based descent or residence patterns.<\/p>\n<p>Our results highlight the complex relationships between genes, language, ethnography, and geography.<\/p>\n<p> <!-- Form created by Optin Forms plugin by WPKube: create beautiful optin forms with ease! --> <!-- https:\/\/wpkube.com\/ --><!--optinforms-form5-container--> <!-- \/ Optin Forms --> <\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/neurosciencenews.com\/maternal-genetics-language-28198\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Summary: A new study explores how cultural practices influence the transmission of native languages, showing that societal norms like matrilineal or patrilineal inheritance can affect linguistic and genetic evolution.
