However, no one worked out the puzzle of this skull until 2021, when researchers proposed that it was a new, unique human species. What’s more, this specimen was alive, at minimum, 146,000 years ago. Analysis also makes scientists believe that this particular skull belonged to a 50-year-old male living in a community in a forested floodplain. Some scientists contend that this species would be the closest extinct relative to modern humans. However, as the New Scientist points out, this claim is highly contested, with others believing that Homo longi is a Denisovan. More specimens would need to be recovered and compared to determine if this is truly a new species.
