EXCLUSIVE Think you're hilarious but your siblings don't find you funny? Scientists discover that humour doesn't run in the family
But if you are worried about following in your Dad's footsteps, don't panic as it's unlikely you'll inherit his humour.
Experts have found that, unlike intelligence or eye colour, humour doesn't run in the family.
In the first ever study to look at the influence of genes and the environment on comedic abilities, scientists asked a thousand twins to create funny captions for cartoons.
By comparing a mix of both identical twins, who share 100 per cent of their DNA, and non-identical twins, who are like any biological siblings and share about 50 per cent of their DNA, their findings revealed there was no evidence that they inherited their humorous talents.
If comedic ability was inherited, then the researchers would have expected to see stronger humour similarities between the identical twins compared to the non-identical twins.
However, they discovered that across all twin pairs, individuals shared the same level of comedic ability, indicating humour is shaped by the environment rather than genetics.
It could also help explain the rarity of comedy duos from the same family - such as the Chuckle Brothers or the Marx Brothers - compared to actors, musicians or writers.
Dr Gil Greengross, from the Psychology Department at Aberystwyth University, led the study, published in the journal Twin Research and Human Genetics.
He said: 'Despite humour's importance, relatively little is known about how we develop our sense of humour or why one sibling can be funny and another cannot.
'Our study's finding that these talents are not inherited is surprising, as it contradicts most research on the heritability of cognitive abilities such as creativity and mathematical skills. So, it is really fascinating.'
He explained that while telling a joke may seem simple, having a good sense of humour is a complex and unique trait that is influenced by a range of psychological attributes and personality characteristics.
'It varies across different social contexts, like when going on a date or entertaining,' he said. 'This may explain why, Chuckle and Marx Brothers aside, there are few successful comedians from the same immediate family.
'What is exciting about this research is it begs the question: if our sense of humour is not handed down from our parents but comes from our environment, what is it precisely that makes us funny?'
The findings also have implications for how scientists think about humour's role in evolution and even dating.
Dr Greengross added: 'These early findings also challenge the widely accepted evolutionary basis of humour.
'A great sense of humour can help ease tension in dangerous situations, foster cooperation, break down interpersonal barriers, and attract mates—all of which enhance survival and reproduction.
'There are also intriguing dating and mating aspects to this. Previous research has shown that women prioritise comedic talents in a partner more than do men, whereas men value a women's ability to appreciate their humour.
'Men experience stronger selection pressure to be funny to impress women, leading to men having slightly higher humour ability, on average — a finding supported by our study.'

Could dengue spread in the UK? Experts fear climate change could bring tropical diseases to Europe
As Europe swelters in extreme heat, experts fear that rising temperatures caused by climate change could push tropical infectious diseases such as Dengue and West Nile Virus into the UK. Researchers estimate that chikungunya and dengue outbreaks could increase five-fold by 2060 under worst-case climate scenarios, according to a report in the Lancet Planetary Health journal. It comes as Europe faces severe heatwaves and wildfires that scientists have attributed to human-induced climate change. There are growing fears that infections could be pushed northwards into Europe, as pathogens thrive in hot and humid conditions. As well as heatwaves, rising greenhouse emissions have forced the world to adapt to floods, droughts and extreme cold. Migration of mosquitos to Europe Changing climate conditions are making Europe more susceptible to both 'vector' and water borne diseases, according to experts. A vector refers to a living organism that can transmit infections from animals to humans or between humans - such as a mosquito. 'Warmer temperatures and altered rainfall patterns caused by climate change mean that certain species of mosquitoes and ticks can now survive in Europe,' Cambridge Professor of Viral Immunology Michael Weekes told The Independent. Dengue, carried by Asian tiger mosquitos, is now one of the fastest growing infectious diseases in Europe. Globalisation and increased travel has brought a slight increase in travellers bringing the infection to Europe, figures show. A total of 304 cases of Dengue were reported in 2024, according to the European Centre for Disease Prevention and Control. This is a large jump from the cumulative total of 275 cases reported over the last 15 years, which scientists believe could point to the disease becoming endemic in Europe. 'Asian tiger mosquitos are now found in Croatia, France, Germany, Portugal and Spain – and can transmit Dengue, chikungunya and Zika viruses,' Prof Weekes added. 'Whereas these generally cause mild infection, Dengue can sometimes cause fever with severe bleeding, and Zika can be transmitted to unborn children.' Flooding and extended periods of rain also disrupt water treatment and distribution processes, scientists fear. A UK government report warned this could cause bacterial blooms and the spread of antibiotic resistant genes. These factors combined mean the disease season is now also longer, with ticks active all year round in some places. Controlling the spread While infectious diseases are rapidly adapting in a shifting climate, Prof Weekes said that Europe can still take measures to accommodate the changes. 'We must reduce greenhouse gas emissions to limit how bad this gets,' Prof Weekes said. 'We also need better surveillance, better control of mosquitos and tick populations, increased vaccination for diseases such as tick-borne encephalitis, and education about avoiding insect bites. The Asian tiger mosquito bites during the day unlike many mosquitos that bite in the evening and at night.' A report released by the UK Health Security Agency (UKHSA) in 2023 also suggested that more research needs to be conducted to obtain better evidence to measure the impact of climate change on infectious disease risk. It called for strong collaboration between national and international public health agencies, cross-governmental agencies, care providers, such as the NHS and farmers, food manufacturers and the public .

Scientists reveal what the perfect man's body looks like - and it's good news for men with dad bods
It's a question that has puzzled men around the world for centuries. What do women really want? Now, scientists may have finally found the answer - at least in terms of male physique. Researchers from the Chinese Academy of Sciences have uncovered the body type that women find most attractive. And their findings will come as good news for men with 'dad bods'. According to the research, the most attractive body mass index (BMI) for men is between 23 and 27. At the higher end, that's actually classed as 'overweight' by the NHS. 'Body fat (adiposity) may be important because it is linked closely (inversely) to circulating testosterone levels and is therefore a better indicator of mate "quality",' the researchers wrote. Ideas about the 'perfect' female body have changed hugely through the years. For example, in the 1950s, weight gain tablets hit the shelves as women aspired to look like Marilyn Monroe and Elizabeth Taylor, while the 90s saw ladies lusting after a thin, androgynous look dubbed 'heroin chic'. However, until now, there have been few studies focusing on the perfect male body. 'Less attention has been paid to the key features driving physical attractiveness of males,' the researchers, led by Fan Xia, wrote in their study, published in Personality and Individual Differences. To get to the bottom of it, the researchers enlisted 283 participants from three countries - China, Lithuania, and the UK. The participants were shown 15 black-and-white images of men ranging in size from BMI 20.1 to 33.7, whose faces had been blurred. The participants were asked to rank the images on a scale from one (least attractive) to nine (most attractive). The results revealed that peak attractiveness corresponded to a BMI of 23.4 in China, 23.0 in Lithuania and 26.6 in the UK. For reference, the NHS classes a BMI of 18.5 to 24.9 as 'healthy', while a BMI of 25 to 29.9 puts you in the 'overweight' category. 'We did not find any large cultural differences in the preferred adiposity, despite the fact there are large differences in the baseline obesity levels in the countries we included and hence big differences in the exposure to individuals with higher body weights,' the team explained. You might think that men would lust after a more trim physique. However, the results showed that both male and female participants preferred bodies with a BMI of between 23 and 27. 'This is probably because it is evolutionarily advantageous for males and females to perceive attractiveness in their own populations in the same way, and most studies including ours indicate this is the case,' the team added. The findings will come as good news for men carrying a few extra pounds. However, the same can't be said for women - as previous studies have shown that men prefer ladies with slimmer physiques. 'Females appear sensitive to adiposity in a manner consistent with evolutionary expectations,' the researchers concluded. 'In contrast earlier work shows males judge females who are thinner than the evolutionary optimal as more attractive.' HOW HAVE IDEAS ABOUT THE 'PERFECT' FEMALE BODY CHANGED? Perceptions of the ideal female body can be linked to representations of women in media, whether found in pop culture, fashion or even politics. These images of feminine attractiveness have changed significantly over the years. 1910 The Gibson Girl - An image produced by American graphic artist Charles Dana Gibson depicted the ideal female figure as tall and regal with an S-curve torso shape 1920 The Flapper - Cultural change sparked by the suffragette movement gave birth to short hair, knee length dresses and a more rambunctious, yet petite, view of female beauty 1950 The Hourglass - Voluptuous curves became important following the end of WWII, which also saw the creation of one of the most influential female bodies, Barbie 1960 The Twig - British cultural icon and model Twiggy brought forward an androgynous look in female ideals where small breasts and thinness were key

Flying ant day 2025: When is it and why does it happen?
The much-maligned "flying ant day", a summer phenomenon in Britain and Ireland, is poised to return as warmer weather persists across the UK. Swarms of winged black garden ants, typically Lasius niger, erupt from their nests under lawns, flower beds, and stone patios to invade personal space, cling to laundry, and splatter against car windshields. Their sheer numbers can be so immense that they have previously registered as drifting clouds on weather radars. Met Office forecaster Simon Partridge told the BBC that distinguishing them from patches of showers can be difficult. The occurrence can be unpleasant and occasionally very irritating – memorably, tennis stars Caroline Wozniacki and Ekaterina Makarova had to interrupt a Wimbledon match in July 2018 to spray themselves with bug repellent as the result of an influx of flying ants to Court 1 – but it is largely harmless to humans and not something to worry about. Nevertheless, to be forewarned is to be forearmed, so here is everything you need to know about this strangest of annual events. Why does it happen? The reason ants emerge from the ground in this sudden fashion is because they have reached the 'nuptial flight' phase of their reproductive cycles, at which point those with wings (known as alates) – virgin queen ants (or princesses) and male drones, but not flightless female workers – depart their nests in search of new colonies, moving as one for protection. As the queens race off, they emit pheromones to attract mates while flying as fast as they can to ensure that only the fastest and most capable males can reach them. This is an example of natural selection in action, as the race makes certain that only the strongest examples of the species get to pass on their genes to a next generation. The spread to fresh colonies further afield also serves to limit inbreeding as it means ants commingle with mates from other nests. A queen – which can grow to 15mm in length and live for as long as 15 years in the wild, according to the Natural History Museum (NHM) – may have several mates during the nuptial flight and preserve their semen within her abdomen for a lifetime, with a view to fertilising future eggs. She will go on to discard her wings by chewing them off and form new nests underground but her male suitors will simply fall to the ground and die without so much as a post-coital cigarette, their final moments on Earth presumably also among their happiest. What weather conditions encourage it? In Britain and Ireland, flying ant days typically occur in July or August, often in warmer urban areas first, when the weather is hot and humid and when winds are low. Temperature is a key factor, with the Royal Society of Biology (RSB) noting that ant swarms rarely emerge if it is cooler than 13C and that 25C is their preferred seasonal average. The RSB, incidentally, argues that we should think of flying ant seasons, rather than isolated days, as ants may well take to the air on multiple occasions over the course of a British summer, depending on the atmospheric conditions, the species of ant in question and the nature of their habitat among other variables. What can be done about it? Not a great deal, unfortunately. Some might advocate flooding the ants' nests with water or detergent or attempting to snare them in sellotape around the home but that all feels distinctly inhumane. Instead, your best bet is to stay out of their way as much as possible and console yourself with the integral role ants play in the maintenance of natural ecosystems. Their colonies help to keep the soil aerated and they themselves are a vital source of food to birds like swifts and gulls, who in turn make important contributions to the natural order. If you do get bitten or stung, do not be alarmed. The NHS states that ant bites are 'generally harmless, although you'll probably feel a nip'.
