Scientists have discovered a new fly that fails its one job
Scientists have discovered a new fly that fails its one job
Scientist have discovered a fly that... can't fly. In December 2021, the John Midgley and Burgert Muller from the Diversity of Pollinating Diptera in South African Biodiversity Hotspots project went to Lesotho, the only country in the world that has its entire territory located at an altitude of 1,000 metres and higher to see what they could find. At the Afriski mountain resort, they found 51 male specimens of Atherimorpha latipennis (a species discovered in 1956 but whose female had never been described) and a for the first time a female belonging to the same species which couldn't get off the ground. “It’s not unheard of for only the female of a species to be flightless,” says Midgley. “But there were no examples in this fly’s family, let alone its genus.” Martin Hauser, a senior dipterologist at the California Department of Food and Agriculture, who was not involved in the research, told the Guardian: “Active flight has only originated four times in the last three billion years, so it’s always interesting when a species loses the ability to fly. It isn’t super surprising to find flightless species. But it is remarkable when the first case of flightlessness is reported in a family.” Scientists could only make educated guesses about why the female had lost the ability to fly. Despite it being much faster than walking, allowing flies to escape predators. “flight is also costly,” said Midgley. “You have to grow wings, and it uses a lot more energy than walking.” “For the males it is worth flying around and being able to search a larger area for females,” said Hauser. “Even if, while flying, they are exposed to birds and other predators, and risk being blown off the mountain and ending up in a hot valley with no females.” Meanwhile, there are other species that can't fly like ostriches, kiwi and emus. It is thought they evolved to lose flight after the dinosaurs became extinct because there were no predators big enough to hunt them. Fly - you had one job...

New study shows that early humans deliberately made stones in spheres
New study shows that early humans deliberately made stones in spheres
A study of 150 stones dating back 1.4m years shows early humans were deliberately crafting spherical shapes – but nobody knows why. The Hebrew University of Jerusalem made findings after analysing the limestone balls which were unearthed in Ubeidiya, a dig site in Israel’s Jordan Rift Valley. Scientists have previously speculated that the stones, which were discovered in the 1960s and serve no discernable purpose, became round after being used as hammers. But the university’s team reconstructed the steps required to create the so-called spheroids and found they were part of a “preconceived goal to make a sphere”. The researchers used 3D analysis to retrace how they were made based on the markings and geometry of the spheroids. They concluded that the objects were intentionally “knapped”, the technique used to shape stone by hitting it with other objects. Antoine Muller, a researcher at the university’s Institute of Archaeology, said: “The main significance of the findings is that these spheroids from ‘Ubeidiya appear to be intentionally made, with the goal of achieving a sphere. “This suggests an appreciation of geometry and symmetry by hominins 1.4 million years ago.” Early humans clearly had some reason for making the balls, but what exactly that is remains a mystery. He said: “We still can’t be confident about what they were used for. A lot of work needs to be done to narrow down their functionality.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
