More people are being born without wisdom teeth and an extra artery in their arm as a result of a human “microevolution” in recent years, a study has found.
Babies now have shorter faces, smaller jaws and extra bones in their legs and feet, a study in the Journal of Anatomy found.
Australian researchers who worked on the paper claim the human race is evolving faster than it has done at any point in the past 250 years.
Over time, human faces have got shorter, which has seen our mouths get smaller, with less room for as many teeth.
As part of natural selection and our increased ability to chew food, this has resulted in fewer people being born with wisdom teeth, Dr Teghan Lucas from Flinders University, Adelaide, said.
“A lot of people thought humans have stopped evolving. But our study shows we are still evolving – faster than at any point in the past 250 years,” she added.
An artery in the forearm that supplies blood to the hand has become more prevalent in newborns since the 19th century, the study also found.
The median artery used to form in the womb but disappear after the baby was born and the radial and ulna arteries had grown.
Now, one in three people keep their median arteries for their whole lives, which poses no health risk and increases blood supply to the hand.
“The median artery is a perfect example of how we are still evolving because people born more recently have a higher prevalence of this artery when compared to humans from previous generations.”
The research was carried out by tracking the rate of retainment of different parts of the body through the generations and dissecting preserved corpses of people born throughout the 20th century.
Nicola Sturgeon’s hospitality shutdown has descended into chaos hours before it is due to come into force after her government failed to define which eateries were able to stay open if they stopped serving alcohol. The First Minister offered a last-minute reprieve to licensed cafes in the Central Belt on Thursday, saying they could stay open if they did not sell alcoholic drinks, but failed to define which outlets would be deemed ‘cafes’, ‘restaurants’ or ‘bars’. This prompted confusion across the industry, with desperate business owners questioning whether their outlets were cafes and allowed to stay open or restaurants and therefore must shut for 16 days at 6pm this evening. Pub owners serving food also questioned why the exemption could not be extended to them if they operated on a dry basis. The confusion deepened on Thursday night after Jason Leitch, Scotland’s national clinical director, said it would be up to council environmental health officers to decide and enforce the rules, contradicting Ms Sturgeon’s statement only hours earlier when she said a “specific exemption” for cafes would be set out in regulations. He was then contradicted by Scottish Government officials, who said the difference between cafes and restaurants would be defined in the new regulations.

Almost a third of all UK coronavirus infections are coming spreading hospitality, business minister Nadhim Zahawi has said. “The evidence that Chris Whitty shared with my colleagues, northern MPs yesterday, does demonstrate that between restaurants, bars and cafes about 30 per cent of the infections are coming through that hospitality, social interactions, if I can describe it as such,” he said.

It’s no secret that Joe Jonas has a large number of tattoos, but Sophie Turner is building a collection of her own that’s nothing to scoff at. (In fact, in 2018 alone she got seven new designs). Turner has an assortment of 13-plus tiny tattoos in total scattered throughout her body and each one has a special meaning. Turner’s personal life, as well as her acting career, have influenced a number of her tattoos. The former Game of Thrones star has two pieces of ink dedicated to the series, as well as two small designs to mark her role in the X-Men franchise. She’s not afraid of getting inked with the people she loves, either. Turner has quite a few matching couple tattoos with her husband, siblings, and best friend/on-screen sister Maisie Williams. Ahead, get a closer look at all of Turner’s tattoos and learn what each one means.
A new lockdown is needed immediately otherwise the country will still be living under social restrictions over Christmas, a Government scientific adviser has warned. Professor John Edmunds, who is a member of the Government’s Scientific Advisory Group for Emergencies (Sage), said drastic measures are now needed to avert a fresh spike in deaths. He recommended a so-called “circuit breaker” lockdown which would reimpose the strict rules seen at the first peak of the outbreak for a short period to quell rising infection rates. Speaking in a webinar for the Royal Society of Medicine, Prof Edmunds, of the London School of Hygiene and Tropical Medicine, said: “I would rather we did it right now, and we took the pain right now.” He claimed the move would help arrest the resurgence of the epidemic before it got out of control and began “overwhelming the health service”, the Evening Standard reported. “I would put the circuit breakers in as fast as we can,” he said. “We should be working from home. We should be taking other measures to reduce our contacts over the winter.” Failure to take decisive action now could also mean the likelihood of the country spending the festive period with their families becomes less likely, the professor said. He said: “If we let the thing get out of hand now, then we will have a lot of cases. That unfortunately means a lot of deaths. “I think we will have a difficult time over Christmas with the virus, and high rates.” His warning came as more than 17,000 new cases of Covid-19 were recorded in the UK yesterday, predominantly in the North West, North East and Yorkshire. Prof Edmunds said: “I hate to be gloomy, but in the North of England now we are not that far away from the health service being stretched.” He claimed the “primary reason” Britain suffered such a heavy death toll at the start of the crisis was due to the Government delaying a full lockdown until March 23. “I think we need to take action rapidly to avoid making the same mistake,” he added. “I really want the Government to act decisively now, rather than waiting and being bounced into acting sometime later.”
Five police officers are under disciplinary investigation for alleged misconduct after they stopped and searched Team GB athlete Bianca Williams in her car this summer, the police watchdog has announced. The Independent Office for Police Conduct (IOPC) said it had advised the five Metropolitan police officers they were subject to a misconduct investigation that will examine whether the couple were treated “less favourably” because of their race. The move puts the IOPC on collision course with the Met police which said that any failings “if proven” would only amount to “minor breaches” of professional behaviour or performance that did not reach the level of misconduct. Williams and her partner, Ricardo dos Santos, a Portuguese sprinter, were stopped by Met officers on July 4 as they drove to their west London home in their Mercedes. The couple were handcuffed while their baby son was in the car in an incident that generated controversy over police conduct and allegations of racial profiling, which the Met denies. Footage of the incident in Maida Vale was shared widely on Twitter at the time after being posted by former Olympic medallist Linford Christie. The police watchdog said officers faced allegations over their treatment of Dos Santos.
Cabinet ministers are at odds over whether to close hairdressers and leisure venues under a new three-tier approach to local lockdowns, The Telegraph has been told. Under the traffic light system due to be unveiled by Boris Johnson within days, areas placed in the top tier of lockdown measures will be forced to close pubs and restaurants. Cities including Manchester, Liverpool and Newcastle are among those expected to be placed in the so-called “red zone”, with Sheffield and Nottingham also thought to be at risk. According to Whitehall insiders, Matt Hancock and health officials are also pushing for leisure venues and hairdressers to be shut. However, the Health Secretary is said to be encountering resistance from a number of Cabinet ‘hawks’ who want to keep as much of the economy open as possible. While the middle and lower tiers of the system are now believed to have been signed off, it is understood the debate has meant that the final list of restrictions in the top tier are still being finalised. It comes after The Daily Telegraph this week revealed that the traffic light system had been held up due to disagreements over who should be responsible for deciding when areas are moved to the highest tier of restrictions. Rishi Sunak is now understood to have won the right to be consulted on pub and restaurant closures after proposals were put forward for a new sign-off process involving him, the Prime Minister and Mr Hancock. According to The Times, Mr Sunak and Alok Sharma, the Business Secretary, also argued for more flexibility in the traffic light system and for greater certainty over when areas should have tighter measures imposed on them. Discussing the latest debate over leisure venues and hairdressers, a senior minister said: “It hasn’t been resolved yet. It’s a heated debate, it’s a very difficult balance and both groups are coming at it from different priorities. “It’s not a case of saving lives or saving the economy, it’s a balance between the two and it’s a fine balance. So obviously there are going to be discussions around that.” However, an ally of Mr Sunak insisted that he was not “just saying no” to tougher restrictions, adding that “all of these decisions are taken in the round.” A Government source also played down suggestions of a row, telling The Telegraph: “Everyone across Government is looking to establish what measures may be needed but no decisions have been taken and work is ongoing. “Everyone supports the strategy of suppressing the virus and protecting the economy.” Separately, leaked documents emerged on Thursday which suggest that the traffic light system will be announced on Monday before coming into force on Wednesday. The papers, seen by the Nottingham Post, suggest that areas placed under mid-tier restrictions will see household mixing banned indoors, as well as at pubs, restaurants and shops. Areas subject to the lower tier of restrictions are likely to be required to abide by the existing 10pm curfew and the rule of six. “There will therefore be no announcements of the Local Risk Levels from central government this week and we are currently seeking to clarify whether or not the Watchlist will be published this week accordingly,” it goes on to state. “Our current expectation is that the approach will be announced on Monday, October 12 with the new standardised regulations coming into force on Wednesday October 14. “Level One and Two measures have now been signed off by Covid O committee but there is further work ongoing on Level 3.”
