Curly hair may have been absolutely critical to humans evolving millions of years ago, scientists have discovered. In fact, having curly hair could have been the key reason as to why humans developed, grew taller and came to have larger brains. It’s all to do with regulating body temperature, according to a new study by researchers at Penn State University. Given that hair can help to protect the head from the sun’s rays, it’s thought that thicker, curlier hair types could have been key to human life progressing in Equatorial Africa. Scientists recreated the kinds of conditions that early humans would have experienced, using wigs featuring different hair types on models. They found that curls were most effective in keeping the models cool in an environment measuring 86 degrees Fahrenheit (30 degrees Celsius) and 60 per cent humidity. Tina Lasisi is the study's lead author. She spoke to Newsweek about the findings and said: "We hypothesized that tightly curled scalp hair would provide some benefits, but the extent of these benefits was uncertain. "Previous studies on mammalian coats have shown that hair can limit the amount of sunlight reaching the skin, but we were particularly surprised by the significant reduction in solar heat radiation impact provided by tightly coiled hair.” The reduction in heat caused by tight curls could have led to the development of larger brains. "Once humans developed large brains, they could employ other behavioral and social strategies to cope with heat, potentially diminishing the relative advantage of curly hair," she said. "This could have led to a diverse distribution of hair textures worldwide. Furthermore, since straight hair better retains heat, populations in colder environments may have experienced selective pressure for straight hair." She added: "Future research should aim to answer these questions by incorporating our data into mathematical models of human physiology or conducting experiments with human subjects who have different hair textures to examine the impact on their thermal regulation.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Senator Dianne Feinstein was briefly hospitalised on Tuesday after suffering what a spokeperson said was a “minor fall” in her California home. The fall, first reported by TMZ, is just the latest incident in a climbing number of health-related issues that have troubled the 90-year-old Feinstein in recent months and is likely to contribute to growing concerns about her ability to serve. The senior California lawmaker only recently returned to Congress after an extended absence due to illness; that departure left Democrats unable to subpoena members of the Supreme Court for a spring hearing about ethics in the nation’s highest judicial authority — though it’s unclear whether she and others on the panel had the stomach for such a move to begin with. “Senator Feinstein briefly went to the hospital yesterday afternoon as a precaution after a minor fall in her home. All of her scans were clear and she returned home,” a spokesperson told the San Francisco Chronicle. Ms Feinstein is set to retire at the end of her term next year. Her succession has sparked a major primary fight in the state of California, with three prominent members of California’s congressional delegation all vying for the job. Her staff, meanwhile, remains adamant that the aging senator remains active and completely able to perform her duties as senator. Those assertions have brushed up sharply against reports in the media of her frequent bouts of confusion throughout the halls of Congress, including numerous instances where she has been heard asking aides where they are guiding her and a recent episode during a committee hearing when the senator began calling for a vote that was already underway. Defenders of the Democratic veteran have claimed that criticisms of her performance and reports of her bouts of confusion are rooted in sexism, arguing that the same concerns are not applied equally to male politicians of similar ages. To be clear, those criticisms are far from only centred around Ms Feinstein; they recently were vocalised in regards to Senate Minority Leader Mitch McConnell by Republicans like Nikki Haley after the former appeared to freeze and become unable to speak at a press conference, before being led away by a colleague. The latest news about Ms Feinstein comes only a week after it was revealed in a news report that she has ceded power of attorney to her daughter.
