Estimating a date of mixture of ancestral South Asian populations Linguistic and genetic studies have demonstrated that almost all groups in South Asia today descend from a mixture of two highly divergent populations: Ancestral North Indians (ANI) related to Central Asians, Middle Easterners and Europeans, and Ancestral South Indians (ASI) not related to any populations outside the Indian subcontinent.
ANI and ASI have been estimated to have diverged from a common ancestor as much as 60,000 years ago, but the date of the ANI-ASI mixture is unknown.
Here we analyze data from about 60 South Asian groups to estimate that major ANI-ASI mixture occurred 1,200-4,000 years ago.
Digital technology and smartphones in particular have transformed many aspects of our society, including how people seek out and establish romantic relationships.
Few Americans had online dating experience when Pew Research Center first polled on the activity in 2005, but today 15% of U. adults report they have used online dating sites or mobile dating apps.
Here are five facts about online dating: Online dating has lost much of its stigma, and a majority of Americans now say online dating is a good way to meet people.
When we first studied online dating habits in 2005, most Americans had little exposure to online dating or to the people who used it, and they tended to view it as a subpar way of meeting people.
Today, nearly half of the public knows someone who uses online dating or who has met a spouse or partner via online dating – and attitudes toward online dating have grown progressively more positive.
To be sure, many people remain puzzled that someone would want to find a romantic partner online – 23% of Americans agree with the statement that “people who use online dating sites are desperate” – but in general it is much more culturally acceptable than it was a decade ago.Online dating has jumped among adults under age 25 as well as those in their late 50s and early 60s.The share of 18- to 24-year-olds who use online dating has roughly tripled from 10% in 2013 to 27% today.Online dating use among 55- to 64-year-olds has also risen substantially since the last Pew Research Center survey on the topic.Today, 12% of 55- to 64-year-olds report ever using an online dating site or mobile dating app versus only 6% in 2013.One factor behind the substantial growth among younger adults is their use of mobile dating apps.
