Jurassic Bark: Do Dogs Hold Hints to Early Language? | GW Today

By John DiConsiglio

Long before we asked them to fetch tennis balls and shake for treats, dogs lived alongside early humans and watched us evolve for as many as 30,000 years. As they shared our hominin homes, our canine companions learned to communicate with gestures like raising their eyebrows and wagging their tails.

But those puppy dog eyes may have been telling us more than just when to scratch their bellies. Courtney Sexton, a fifth-year PhD candidate in the Department of Anthropology Center for the Advanced Study of Human Paleobiology (CASHP) within the Columbian College of Arts & Sciences, believes our best friends can offer some of our best insights into how early human language may have evolved. In her research, she looks at whether dogs’ nonverbal signals could have mirrored our own developing communication skills.

“Most [anthropology] research comes down to the essential question of what makes humans humans,” she said. “I argue that, in some ways, we’re people because of dogs.”

No animals have shared our environment quite like dogs. “You don’t see such a unique model of interspecies interaction anywhere else in the animal kingdom,” Sexton said. But when researching the roots of human communication, studies have largely turned to non-human primate subjects—an obvious choice given our genetic links. Our closest living relatives, primates developed strategies to communicate wordlessly through features like their brightly colored facial patterns. They may raise a distinctive eyebrow, for example, to exaggerate an expression.

An evolutionary anthropologist and dog lover, Sexton noticed some of those same characteristics in her late pet Remy, a black and white hound with a playful personality and distinctive facial markings. Not unlike primates, dogs use their expressions, muscle movements and facial features to signal their needs. But since dogs’ behavior is often a response to human attention—in a sense, reacting to what they see in their owners—Sexton theorized that their mannerisms might be windows into our own communication development.

“Before we had language, we used other tools to communicate. And all that time, dogs were alongside us, watching,” she explained. “Did dogs hone into these [tools] and use them to communicate back to us? Are they giving us clues to how language emerged in our species?”

Sexton originally planned to study dogs with her collaborators at Harvard University’s Evolutionary Neuroscience Laboratory. But when the COVID-19 pandemic curtailed travel, she used social media, outreach events and word-of-mouth to collect more than 100 videos of dogs reacting to test prompts. With her new two-year-old hound Sonder at her side, she dissected thousands of frame-by-frame images across breeds. “I was floored by the response,” she said. During the pandemic, “a lot of people were stuck at home with their dogs and they agreed to become community scientists for this project.”

Associate Professor of Anthropology Brenda Bradley, Sexton’s thesis advisor, found the research trail fascinating, but was initially skeptical that it complemented the CASHP program’s focus on human/hominin evolution. “The evolution of sociality and communication in dogs is not a focal topic for us,” she laughed. But she soon realized Sexton’s work was “a stroke of luck” that bridged the expertise of several CASHP faculty— from Associate Professor of Speech, Language and Hearing Sciences Francys Subiaul’s work on the development of social cognition and Professor of Anthropology Chet Sherwood’s study of the evolution of communication skills to Bradley’s own research into the evolutionary basis of facial traits and pigmentation. “Our lab is interested in the evolution of these patterns in monkeys and lemurs but it parallels Courtney’s work on dogs,” she noted. “It has been hugely informative for the primate projects.”

Dogs have long been at the center of Sexton’s work and life, from the setters she grew up with to the therapy and rescue dogs she’s helped train. A former Mass Media Fellow with the American Association for the Advancement of Science and a writer for Smithsonian magazine, Sexton has worked with the nonprofit Defenders of Wildlife on conservation campaigns for wolves, dogs’ canine relatives.

Her research has also made her a popular guest lecturer in GW undergraduate classes on human evolution and biological anthropology. She’s spoken to other area universities on topics from cognitive science to the mental abilities of animals. And she regularly hosts public outreach workshops to teach dog owners how to better understand canine behavior.

Indeed, Sexton hopes her anthropology research will prove equally valuable to animal welfare. By deciphering the signals dogs send us, Sexton envisions her studies leading to better training for service dogs and more success in placing shelter pets. “We always expect dogs to know what we’re telling them,” she said. “But if we can learn more about the messages they’re sending, we can actually help them as much as they help us.”


Why Haven’t There Been Any Evangelicals on the Supreme Cour…

With the nomination of Judge Ketanji Brown Jackson last month, the US Supreme Court could get its first Black female and first nondenominational Protestant justice.

Six of the current Supreme Court justices are Catholic (Samuel Alito, Amy Coney Barrett, Brett Kavanaugh, John Roberts, Sonia Sotomayor, and Clarence Thomas), and with Stephen Breyer’s retirement, Elena Kagan will be the only Jewish justice. In response to a question during her confirmation hearings on Tuesday, Jackson described her faith as “Protestant” and then added “nondenominational.”

When Judge Neil Gorsuch was confirmed to the US Supreme Court in 2017, he ended a seven-year stretch when no Protestants sat on the nation’s highest court for the first time in history. Of the 115 justices appointed to the Supreme Court since 1789, the overwhelming majority have been Protestants, but none have identified as nondenominational or evangelical.

“Since the rise of politically active evangelicals in the 1970s, not a single evangelical has served on the Supreme Court,” Dan Crane, Frederick Paul Furth Sr. professor of law at University of Michigan, told Christianity Today. “It’s not that they don’t care about the court, but they haven’t served on the court.”

The high court’s decisions on abortion and school prayer helped galvanize the Religious Right, but conservatives have focused more on outcomes than the identities behind the bench.

“Activism is usually mentioned as one core distinctive of being an evangelical, but we oppose it on the bench,” CT observed in 2006. “Is this why there are so few top-level evangelical judges?”

The lack of evangelicals on the Supreme Court is partly a supply issue. While evangelicals make up a quarter of the American population, Crane found that they’re just 7 percent of the student body at the country’s top law schools. Harvard and Yale are seen as the Supreme Court “pipeline,” with eight of the nine justices—and nominee Brown—having attended law school there.

There are also differing attitudes among evangelicals around legal scholarship. Crane remembers that when he attended Wheaton in the late ’80s, the faculty discouraged students from applying to law schools. He thinks there’s still some baggage around legal practice—which can be seen as a worldly, greedy profession—and fewer evangelical students want to work to distinguish themselves in elite legal circles the same way they embrace the ambition needed to succeed in other areas like elite sports or business.

It’s also a result of a stubborn current of anti-intellectualism still prevalent in evangelicalism, the same issues Mark Noll addressed in his 1994 book The Scandal of the Evangelical Mind.

“Because evangelicalism comes out of fundamentalism, which is anti-intellectual, American evangelicalism continues to operate in the long tail of this,” Crane said. “It’s not inherent in Protestantism, but it’s a manifestation of American evangelicalism.”

As a whole, evangelicals tend to pursue less formal education than Catholics and Jews. A Pew Research Center study found that in 2014, 7 percent of evangelicals had a postgraduate degree, compared with 10 percent of Catholics and 31 percent of Jewish people.

“The reality of social conservatism: Evangelicals supply the political energy, Catholics the intellectual heft,” Franklin Foer wrote in The New Republic in 2005. “Evangelicals didn’t just need Catholic bodies; they needed Catholic minds to supply them with rhetoric that relied more heavily on morality than biblical quotation.”

Catholic and evangelical legal thought overlap considerably, particularly in their understanding of natural law, which dates all the way back to Thomas Aquinas. But where Catholics have a body of legal thought that is systematized and steeped in logic and scholarship, evangelicals are more likely to appeal solely to Scripture for their natural law arguments, said Robert Cochran, Louis D. Brandeis professor of law emeritus at Pepperdine University School of Law.

“Natural law proponents draw insights from Scripture, but the primary source of natural law—reason—is available to all, creating the possibility of a common legal agenda for people of all faiths and of no faith,” Cochran said. “Evangelicals tend to express themselves and their moral convictions in biblical terms that have great insight, but are less likely to draw the broad support in an increasingly pluralistic society.”

Evangelicals also tend to see the church as the primary cultural institution, encouraging their sharpest minds to pursue pastoral ministry rather than more worldly pursuits.

“Many evangelicals still tend to think in separatist terms,” he said. “They see the church as the primary cultural institution, their brightest young people become pastors, and they focus their attention on what Christ is doing in their church, rather than what he might be doing in law or other aspects of culture.”

Still, a few evangelicals have made the Supreme Court short lists.

Former federal circuit court judge and constitutional law scholar Michael McConnell—a devout Presbyterian—was suggested as a possible nominee during the John McCain and Mitt Romney presidential campaigns. Raymond Kethledge, an evangelical judge from the US Court of Appeals for the 6th Circuit, made Trump’s short list in 2018. And George W. Bush nominated evangelical attorney Harriet Miers in 2005. Kethledge was never nominated, and Meyers withdrew her nomination, and in both cases the judge confirmed was a conservative Roman Catholic (Alito and Kavanaugh, respectively).

But with many of the views and values evangelicals prioritize faithfully represented by the court’s conservative Catholic justices, Christian legal scholars don’t see the absence of evangelicals on the high court as a problem in itself. On the two issues that seem most important to evangelicals—religious liberty and abortion—conservative evangelical and conservative Catholic legal philosophies share common ground.

“To the extent social views influence Court decisions, my sense is that most conservative Catholic and evangelical legal scholars share similar views, so as to outcomes, it is not so important that there be evangelical, as opposed to Catholic, justices,” Cochran said.

And the enthusiasm evangelicals show for conservative Catholic justices is a sign of progress. According to Thomas Berg, that evangelicals will embrace conservative Catholic judicial nominees indicates how closely aligned evangelicals and conservative Catholics now are on social issues like abortion and religious liberty. Berg, the James L. Oberstar professor of law and public policy at University of St. Thomas School of Law, applauds this support as a welcome change from bitter anti-Catholic sentiment so prevalent in the 1960s.

There is the Constitutional prohibition against a religious test as a qualification for holding office, and scholars vehemently denounce the idea of identity politics on the Supreme Court.

“We should want justices who understand that their job is to say what the law is, not what it should be,” said Ernie Walton, associate dean of administration and admission at Regent University School of Law. “Having a justice who understands this and has internalized it is far more important than the religious, ethnic background, or gender of the justice.”

Berg also noted that there are many factors impacting a Supreme Court nomination that have nothing to do with faith tradition but are just the result of chance. Presidents seem to look for relatively young justices who will serve on the court for several decades. An evangelical might have the professional credentials, but the president might look for judges who more align with their political and judicial philosophy.

The qualities that caused Michael McConnell’s name to come up when speculating about a McCain or Romney win likely made him unappealing to Barack Obama. And while Kethledge reportedly made Trump’s short list in 2018, the nomination ultimately went to Brett Kavanaugh.

“Conservative white evangelicals are underrepresented in the [Supreme Court candidate] pool because of educational, cultural, theological differences,” Berg said, “But once you get to the actual decision, so many things affect the decision that even the candidates who reach that point can be knocked out for any number of reasons.”

Berg also emphasized that there’s a difference between Black evangelicals and conservative white evangelicals, and most of his observations pertain to conservative white evangelicals.

Jackson’s friends and colleagues described her to ABC News as having faith that is “private and deeply personal, neither a frequent topic of conversation nor an overly outward display.” The African Methodist Episcopal (AME) Church released a statement in support of her nomination, but the statement did not indicate that she is affiliated with an AME church.

“I’m certain her faith will come up [in this week’s hearings] in terms of how it has informed her views of the world and the law,” said ABC News legal analyst Sarah Isgur, “but I doubt it will be a point of contention so much as a point of pride.”

Isgur was right. Senator Lindsay Graham asked Jackson about her faith. “Personally my faith is very important to me,” she said, “but as you know, there’s no religious test in the Constitution under Article XI and it’s very important to set aside one’s personal views about things in the role of a judge.”

Jackson has rarely spoken at churches, but one instance—her most public faith display—involves her role on the board of Montrose Christian School, a now-defunct Southern Baptist school in Maryland. Jackson served on the school’s board from 2010 to 2011.

At her confirmation hearing for the DC Circuit in April 2021, senator Josh Hawley asked Jackson whether, based on her service at Montrose Christian, she believed in “the principle, and the constitutional right, of religious liberty.”

“I do believe in religious liberty,” Jackson told Hawley, calling religious liberty a “foundational tenet of our entire government.” But Jackson distanced herself from the Montrose Christian statement of faith, telling Hawley that she had served on many boards and did not necessarily agree with every statement those boards might make. And in this case, she added, she was unaware of the Montrose statement of beliefs.

Though there might not be an evangelical on the Supreme Court, that doesn’t mean that evangelicals don’t have influence in the judicial system.

“There are many evangelical judges on the lower federal courts and state supreme courts, as well evangelical lawyers who land top federal clerkships right out of law school,” Walton said. With time, he expects an evangelical will make it to the Supreme Court.

And evangelical legal institutions might be gaining momentum to compete with the traditional Supreme Court pipeline. Walton noted that in 2020 and 2021, over 20 percent of Regent’s law school graduates went on to work in clerkships, earning the school a top-25 ranking in the nation.

So as evangelical law schools produce top-notch legal minds and evangelicals value the changes that come not just through pastoral ministry but every vocational calling, the odds of an evangelical justice could increase.

“God knows what lies ahead of each of us,” Jackson said in a 2011 commencement address at Montrose Christian School. “The best that you can do, as you look forward, is to take the long view.”
