Ancient DNA Gives Rare Snapshot of Neanderthal Family TiesCurrent Event Close Reading and Critical Thinking Questions for Social Studies Teachers
The following Social Studies event discussion is based on the original news article "Ancient DNA Gives Rare Snapshot of Neanderthal Family Ties," by Maddie Burakoff, published October 19, 2022, in AP News. The article reports on a new study that suggests Neanderthals formed small, tight-knit communities where females may have traveled to move in with their mates.
Below you will find the article and some critical thinking questions to pose to your Social Studies students.
NEW YORK (AP)—A new study suggests Neanderthals formed small, tightknit communities where females may have traveled to move in with their mates.
The research used genetic sleuthing to offer a rare snapshot of Neanderthal family dynamics—including a father and his teenage daughter who lived together in Siberia more than 50,000 years ago.
Researchers were able to pull DNA out of tiny bone fragments found in two Russian caves. In their study, published Wednesday in the journal Nature, they used the genetic data to map out relationships between 13 different Neanderthals and get clues to how they lived.
“When I work on a bone or two, it’s very easy to forget that these are actually people with their own lives and stories,” said study author Bence Viola, an anthropologist at the University of Toronto. “Figuring out how they’re related to each other really makes them much more human.”
Our ancient cousins, the Neanderthals, lived across Europe and Asia for hundreds of thousands of years. They died out around 40,000 years ago, shortly after our species, the Homo sapiens, arrived in Europe from Africa.
Scientists have only recently been able to dig around in these early humans’ DNA. New Nobel laureate Svante Paabo—who is an author on this latest study—published the first draft of a Neanderthal genome a little over a decade ago.
Since then, scientists have sequenced 18 Neanderthal genomes, said lead author Laurits Skov, a geneticist at the Max Planck Institute for Evolutionary Anthropology. But it’s rare to find bones from multiple Neanderthals from the same time and place, he said—which is why these cave discoveries were so special.
“If there was ever a chance to find a Neanderthal community, this would be it,” Skov said.
The caves, located in remote foothills above a river valley, have been a rich source of materials from stone tools to fossil fragments, Viola said. With their prime view of migrating herds in the valley below, researchers think the caves might have served as a short-term hunting stop for Neanderthals.
Archaeologists excavating the caves have found remains from at least a dozen different Neanderthals, Viola said. These remains usually come in small bits and pieces—“a finger bone here, a tooth there”—but they’re enough for scientists to extract valuable DNA details.
The researchers were able to identify a couple of relatives among the group. Along with the father and daughter, there was a pair of other relatives—maybe a boy and his aunt, or a couple of cousins.
Overall, the analysis found that everyone in the group had a lot of DNA in common. That suggests that at least in this area, Neanderthals lived in very small communities of 10 to 20 individuals, the authors concluded.
But not everyone in these groups stayed put, according to the study.
Researchers looked at other genetic clues from mitochondrial DNA, which is passed down on the mother’s side, and the Y chromosome, which is passed down on the father’s side.
The female side showed more genetic differences than the male side—which means females may have moved around more, Skov said. It’s possible that when a female Neanderthal found a mate, she would leave home to live with his family.
University of Wisconsin anthropologist John Hawks, who was not involved in the study, said the research was an exciting application of ancient DNA evidence, even as many questions remain about Neanderthal social structures and lifestyles.
Figuring out how early humans lived is like “putting together a puzzle where we have many, many missing pieces,” Hawks said. But this study means “somebody’s dumped a bunch more pieces on the table.”
Critical Thinking Questions
- The first section of an article should answer the questions “Who?” “What?” “When?” and “Where?” Identify the four W’s of this article. NOTE: The rest of the article provides details on the why and/or how.
- Does this article have any bias? Why or why not?
- What kind of data or evidence did researchers use to prove ties between a group of Neanderthals?
- Describe the relationships researchers found between the Neanderthals.
- How long ago did Neanderthals live, and when did they die out? Did they live alongside Homo sapiens (modern humans)?
- What is significant about the caves where the Neanderthal bones were found? What made this area a good place to live?
- How does Laurits Skov, the lead author on this study, describe the way female Neanderthals might have lived? What evidence does he give?
- Respond to the following quote by study author Bence Viola: “When I work on a bone or two, it’s very easy to forget that these are actually people with their own lives and stories... Figuring out how they’re related to each other really makes them much more human.” What does Viola mean, and why might it be important or valuable to come to this conclusion?
- What can studying ancient humans tell us about the way we live today?
- Imagine you are interviewing the authors of this study. Write three questions you would ask that would improve your understanding of their findings.
