PARIS — Women speak to their male partners less often as they grow older and turn their attention to a younger generation, according to an unusual study Thursday that tracked nearly two billion phone calls and text messages.
The findings back evolutionary theory about the role of women in the survival of the genes, according to the probe by researchers in Britain, Finland, the United States and Hungary.
The investigators tracked the origin and destination of cellphone calls and text messages among 3.2 million people over seven months.
The changing web of contacts showed how men and women’s social strategies mutate over time, the paper says.
“This suggests that the intimate structure of human social networks are driven much more by women’s interests than by men’s,” said Robin Dunbar from Oxford University’s Institute of Cognitive and Evolutionary Anthropology.
“Men are more casual in their social relationships, whereas women know what their social goals are and go for them.”
Women spent more time communicating with the opposite sex when they were of childbearing age, the scientists said.
After the age of 45, women tended to shift their attentions to a much younger female — presumed to be a daughter — as their focus shifted to grandchildren.
Men’s most frequent contact throughout their lives was consistently with their wife or girlfriend, although they made fewer calls than women did.
Co-author Kimmo Kaski of Finland’s Aalto University told AFP the results were “maybe sort of obvious”, but this was the first evidence borne out by actual data.
The researchers knew only the age and gender of the subjects, the duration of their calls and the number of messages sent, as well as their postal codes. The information was provided by an unidentified phone company in a European country. Identities and other data were withheld.
The study appears in the journal Scientific Reports.
Trump-loving neo-Nazi charged with insanely violent threats against Latino woman
Federal agents arrested a Washington state man who allegedly threatened to "exterminate" Latinos as part of a race war he believed would be launched by President Donald Trump.
According to court documents, Eric Lin frequently praised Nazi leader Adolf Hitler online and sent multiple death threats against a woman in Miami and plotted to pay a man to beat her up, reported the Miami New Times.
"The time will come when Miami will burn to the ground — and every Latin Man will be lined up against a Wall and Shot and every Latin Woman Raped or Cut to Pieces," Lin wrote Aug. 8, according to investigators.
Republican senator heckled and booed during raucous town hall for blaming mass shootings on mental illness
Iowa Sen. Joni Ernst, who is up for reelection in 2020 and is among the Republican senators who is considered vulnerable, discussed the recent mass shootings in El Paso, Texas and Dayton, Ohio during a town hall event in her home state this week —and she was booed and heckled when she echoed President Donald Trump’s rhetoric and blamed “mental illness” for the killings.
Republicans likely to block ‘background checks’ after Trump’s abrupt reversal: report
After two mass shootings over one weekend, President Donald Trump signaled that he would be open to strengthening background checks.
He promptly dropped his resolve to sign gun regulations one week later when he said that there were already strong background checks on the books.
With the president's apparent reversal, Republicans in Congress also appear to be abandoning legislation, reports Politico.
“I really don’t see the dynamic having really changed there much,” Senate Homeland Security Chairman Ron Johnson told Politico. “I don’t anticipate we’re going to pass a federal red flag law."
