A man’s world? Not according to biology or history.

Many of us look at the stranglehold that gender-based oppression has on our societies and wonder if there was a time when men didn’t have this much power, when femininity and masculinity didn’t mean what they do now. When we search for powerful women in ancient history, when we try to identify precedents for equality in the distant past, perhaps we also betray our longing for an alternative in a world in which we fear there may be none.

Patriarchy—giving all power and authority to the father—can sometimes seem like a vast conspiracy stretching into deep time. The word itself has become devastatingly monolithic, encompassing all the ways in which the world’s women, girls, and nonbinary people are abused and unfairly treated, from domestic violence and rape to the gender pay gap and moral double standards. The sheer scale of it feels out of our control. But how old and how universal is it really?

Historians, anthropologists, archaeologists, and feminists have been fascinated by this question—and as a science journalist, I’ve been preoccupied with it for years.

In most cases, matrilineal societies are framed as unusual circumstances, “beset by special strains, as fragile and rare, possibly even doomed to extinction,” as Washington State University anthropologist Linda Stone puts it. In academic circles, the problem is known as the matrilineal puzzle. Patriliny, on the other hand, is seen to need no explanation. It just is.

Small differences in mom’s behavior may show up in child’s epigenome

Adding evidence to the importance of early development, a new study links neutral maternal behavior toward infants with an epigenetic change in children related to stress response.

Epigenetics are molecular processes independent of DNA that influence gene behavior. In this study, researchers found that neutral or awkward behavior of mothers with their babies at 12 months correlated with an epigenetic change called methylation, or the addition of methane and carbon molecules, on a gene called NR3C1 when the children were 7 years old. This gene has been associated with regulating the body’s response to stress.

“There is evidence of a relationship between the quality of maternal-infant interaction and methylation of this gene though these are small effects in response to a relatively small variation in interaction,” said Elizabeth Holdsworth, a Washington State University biological anthropologist and lead author of the study published in the American Journal of Human Biology.

Other studies have connected extreme stress in early life, like neglect and abuse, to more dramatic methylation on this particular gene in adults. However, Holdsworth emphasized that the small difference indicated by this study may be an indication of normal human variation and it’s hard to determine if there are any long-term effects.

New study suggests Mayas utilized market-based economics

More than 500 years ago in the midwestern Guatemalan highlands, Maya people bought and sold goods with far less oversight from their rulers than many archeologists previously thought.

That’s according to a new study in Latin American Antiquity that shows the ruling K’iche’ elite took a hands-off approach when it came to managing the procurement and trade of obsidian by people outside their region of central control.

In these areas, access to nearby sources of obsidian, a glasslike rock used to make tools and weapons, was managed by local people through independent and diverse acquisition networks. Overtime, the availability of obsidian resources and the prevalence of craftsmen to shape it resulted in a system that is in many ways suggestive of contemporary market-based economies.

“Scholars have generally assumed that the obsidian trade was managed by Maya rulers, but our research shows that this wasn’t the case at least in this area,” said Rachel Horowitz, lead author of the study and an assistant professor of anthropology at Washington State University. “People seem to have had a good deal of economic freedom including being able to go to places similar to the supermarkets we have today to buy and sell goods from craftsmen.”

What is anxiety?

National Public Radio’s Rhitu Chatteriee interviewed WSU anthropology professor Ed Hagen, among others, to expand understanding of anxiety.

JUANA SUMMERS, HOST:

Americans are anxious. Nearly three years of a pandemic, political unrest and ongoing economic instability have left people feeling fearful, ill at ease. This week, we’re spending some time understanding anxiety. We will kick off the series with a simple question – what is anxiety? NPR’s health correspondent Rhitu Chatterjee went looking for the answer and brings us this story.

RHITU CHATTERJEE: Most of us have experienced anxiety at some point in our lives, and we know how it shows up in our bodies – racing thoughts, struggling to sit still, queasy stomach, sensations that bring a sense of dread.

Ed Hagen.

CHATTERJEE: …anxiety can be adaptive. That’s why researchers think that it probably played a key role in human evolution because it alerted our ancestors to threats in their environment. Ed Hagen studies the evolution of emotions and mental illnesses at Washington State University.

ED HAGEN: And if you look at the kinds of things that people tend to be anxious about, they do seem to line up with those kinds of longstanding evolutionary threats.

CHATTERJEE: Like predators, poisonous foods and animals, disease and even social threats.

HAGEN: Most of us are, you know, really concerned that we maintain a good reputation with our friends and group members.

Ancient dart throwing provides introduction to experimental archeology

The first complex weapon system developed by humans is helping Washington State University students learn about both ancient technological innovation and modern-day experimental archeology.

Originating in Europe over 30,000 years ago, the “atlatl” consists of a short stick or board with a cup at one end that enables the wielder to throw a dart further and with more force than a spear. The weapon pre-dates the bow and is still used around the world today to hunt large game.

On a cloudy afternoon earlier this semester on the Thompson Flats at WSU Pullman, students in Shannon Tushingham’s archeological methods and interpretation class had the unique opportunity to hunt wooly mammoths with the ancient weapon system. The key difference between the students’ mammoth hunt and that of their ancient ancestors was that the mammoths at WSU were made of cardboard.

“I find that my students just love anything hands on, and this is a real fun one,” Tushingham said. “Whenever you get to throw projectiles in class, it is a big hit.”
