>Analyzing fossils from a cave in Russia, scientists have found the first known Neanderthal family: a father, his teenage daughter and others who were probably close cousins.

>The findings, published on Wednesday in the journal Nature, painted a tragic picture of our extinct relatives, who roamed Eurasia tens of thousands of years ago. The family, part of a band of 11 Neanderthals found together in the cave, most likely died together, scientists said, possibly from starvation.

>The study was carried out by a team of researchers that included Svante Pääbo, a Swedish geneticist who for 25 years has been uncovering the secrets of Neanderthals, from extracting their DNA from cave floor dirt to replicating their brain cells. Earlier this month, he won the Nobel Prize for his efforts.

>“I would not have thought we would be able to detect a father and daughter from bone fragments, or Neanderthal DNA in cave sediments, or any other of the things that are now becoming almost routine,” said Dr. Pääbo, a director at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. “It has been an amazing journey.”

>For his first study of Neanderthal DNA in 1997, Dr. Pääbo and his colleagues drilled into a skull cap discovered in 1856 in a German quarry. Over the next few years, they gathered more DNA from other museum specimens, collecting hints about the evolution of Neanderthals and their links with living humans. Eventually, Dr. Pääbo and his collaborators dug up enough ancient DNA to reconstruct the entire Neanderthal genome.

>The new discovery came from a Siberian cave called Chagyrskaya. Paleoanthropologists with the Russian Academy of Sciences began digging there in 2007, unearthing fragments of Neanderthal bones and teeth. The researchers have also found 90,000 stone tools in the cave, along with butchered bison bones.

>The cave may have served as a seasonal home for the Neanderthals. They may have come to Chagyrskaya to hunt bison that migrated each year to graze on the nearby grasslands.
>
>In 2020, Dr. Pääbo and his colleagues published the first DNA findings from Chagyrskaya: a full genome collected from a Neanderthal woman’s finger bone. Her genes showed that she was more closely related to Neanderthals more than 3,000 miles away in Croatia than those just 65 miles away in another cave known as Denisova.

>That kinship suggests that the Neanderthals in Siberia did not belong to a single population. They expanded east from Europe at least twice — first to Denisova, then tens of thousands of years later to Chagyrskaya.

>Dr. Pääbo’s team continued testing other Neanderthal fossils from the cave. They hit a genetic mother lode, ending up with DNA from 11 individuals: six adults and five children. The fossils — along with the stone tools and bison bones — all rested in the same layer of sediment in the cave.

>“Archaeologists call this a ‘short occupation,’” said Laurits Skov, a postdoctoral researcher at the University of California, Berkeley, who was a co-author of the new study. In other words, the bones were all trapped in this layer of dirt within a relatively short span of time, geologically speaking. “But ‘short’ here means a couple thousand years or less.”

>Still, Dr. Skov thinks that the 11 Neanderthals all lived around the same time. That’s because many of them were close relatives.

>To look for kinship among the Neanderthals, Dr. Skov and his colleagues scanned the DNA of the fossils for tiny variations. Two of the fossils shared enough variations that they had to be first-degree relatives. One came from a broken vertebra that appeared to belong to an adult male. The other came from a tooth that seemed to come from a teenage female. If these estimated ages were accurate, then the specimens could have come from siblings, or from a father and his daughter.

>The DNA from the fossils allowed the researchers to pin down the relationship more precisely. The scientists took advantage of the fact that mothers pass down an extra set of genes to their children, called mitochondrial DNA. The Chagyrskaya man and the girl had different mitochondrial DNA, ruling out a sibling relationship.

So your average Russian family.
Nothing changes
