The Norse-built ship likely sank during bad weather. The lake’s freshwater environment has caused the ship to appear frozen in time, apart from a little corrosion on its iron nails. The ship was discovered during a sonar survey, which has been used to locate dumped munitions. Researchers believe the ship, with unique stem posts and overlapped planks, dates to between the 1300s and 1800s. Marine archaeologists have found a well-preserved medieval shipwreck resting at the bottom of Mjøsa, the largest lake in Norway. The study doesn’t draw a direct comparison between chimps and our early ancestors, but it has suggested scientists need to take a deeper look at the anatomy of ancient humans and how they moved.Īn autonomous underwater vehicle named Hugin (left) surveys a Norwegian lake. Much of the time, the chimps walked upright among the trees. Scientists spent more than a year observing adult chimpanzees in an environment similar to what our early human ancestors encountered - a mix of open land and dense forest. Previous studies have suggested that ancient human relatives evolved to walk on two legs because they lived in an open savanna - but the latest research contradicts that popular theory.
Bipedalism may have started up in the trees. Wild chimpanzees in Tanzania have provided researchers with new insights on our ability to walk upright. The rover’s microphone happened to be turned on at the time, and the robotic explorer captured the eerie sounds in an audio recording released this week. While Perseverance was investigating Jezero Crater on Mars in 2021, a towering whirlwind of dust passed right over it. The rover is also plotting a course up the steep bank of an ancient river delta and will begin studying the intriguing material there in February. These samples are part of a matching set that will remain stowed on the rover - and either cache could be the collection that makes its way back to Earth in 2033 through the Mars Sample Return program. The rover is about to build the first depot on another world as it drops a collection of rock and dust samples on the Martian surface. Perseverance isn’t letting any dust gather under its wheels. The Perseverance rover is about to build a sample depot on Mars.
