Review of 'Rough and Tumble: Aggression, Hunting, and Human Evolution'

Intellectual Affairs

As epiphanies go, it was hallucinatory and a little disconcerting… I had been reading about human evolution for a couple of weeks, off and on, trying to wrap my mind around the sheer span of the time involved -- the hundreds of thousands of generations, running back (the current estimate goes) some four million years.

Arguably the story begins a million or two years earlier still, when some kind of proto-hominid emerged from the line that led to the chimpanzees and the bonobos. Humans share more than 99 percent of our DNA with them. We’ve done a lot with the upright posture and those opposable thumbs. The past two million years – the period between Australopithecus and Homo sapiens digitalis – looks positively frenzied by contrast with the usual pace of evolution. And yet we are still distant cousins of the chimps, despite our gift for exalting humankind as existing above nature, or outside it.

One day, while reading these facts and thinking these thoughts, I looked up to see that a very strange thing had happened to everyone around me. They were, all of them, tangibly and unmistakably primates. (Or rather, we were, since my own hand suddenly looked like a well-articulated variety of paw.)

It is one thing to understand evolution at a conceptual level; a fairly difficult thing. Experiencing the continuity between human beings and other species is something else altogether; something like a waking dream. And perhaps especially when seated in a bakery frequented by lawyers, lobbyists, and media people from nearby offices – wearing clothes and mostly fur-less, but still recognizable as mammals distantly akin to monkeys or apes, despite obvious differences in carriage and demeanor.

They (we, rather) were eating scones for breakfast, not chunks of raw antelope. But for a few dizzying moments there, this did not seem as large a difference as it ordinarily might.

Fair warning, then: Reading Travis Rayne Pickering’s Rough and Tumble: Aggression, Hunting, and Human Evolution (University of California Press) may well leave the bright line between nature and culture looking thinner and blurrier than usual. (Pickering is professor of anthropology at the University of Wisconsin at Madison.) I should also warn vegans against reading the book, unless they are in a particularly argumentative mood.

More on that in due course. First, a look at the perennial dispute that Pickering has joined about the source of mankind’s history of violence. One familiar bull-session or editorial-page option is to understand the penchant for violence as an intrinsic and inescapable human disposition, something for which we are genetically  programmed, even. In support of this idea, one can cite Jane Goodall’s discovery about the chimps she observed in the wild. While sociable amongst themselves, members of one band were capable not just of killing outsiders but of teaming up to wipe out the young males in another group.

And remember, we share 99 percent of our DNA with the chimps. Case closed! Well, perhaps not, since we have the same margin of genetic overlap with the bonobos. “In general,” Pickering writes, “bonobos engage in sexual contact frequently and casually, in many cases to seemingly allay what could otherwise turn into aggressive interaction.” Besides making love, not war, bonobos in the wild “hunt less frequently than do wild chimpanzees.”

Bunch of hippies. Anyway, the old Hobbes vs. Rousseau dichotomy cannot be decided by consulting the genome -- and the fossil record suggests a more blended perspective on what human beings are and how we got here.

Pickering moves through the evidence and hypotheses about our prehistory with an eye on the disputes they have inspired among paleoarcheologists. Some of them sound quite nasty. (The disputes, that is, though a couple of the researchers also come across as petty and vicious.) I’ll sketch the author’s own conclusions here briefly, but what makes the book especially interesting is its tour of the disciplinary battlefield.

The brains and teeth of our distant ancestors give reason to think they were hunters: regular, successful hunters, at that. The brain consumes a lot of energy. Once proto-humans left the jungles to roam the savanna, their brains grew considerably and at a relatively rapid pace – something a steady diet of meat could only have helped. (And vice versa, since “acquiring meat presumably requires a smarter brain than does picking stationary nuts or grubbing for fixed roots.”)

Besides being available “in the form of large herds of grazing ungulates,” meat “is also soft and does not require that its consumers have a massive dental battery to break it down in the mouth.” Furthermore, the teeth in hominid fossils do not show the kinds and quantity of abrasion found in mammals that normally consume seeds and nuts (also sources of protein) in quantity.

Meat “adheres to bones, comes in large packages, and is stubbornly encased in hairy, elastic hides, so a cutting technology would have been most useful for a blunt-toothed [primate] that had begun to exploit this resource.” Pickering considers the fossil evidence not just of tools and weapons but of animal bones scored with knife-marks left by prehistoric butchers.

But our ancestors’ diet is only part of the story, since the author is less interested in what they ate than in how they developed the capacity to do so regularly. Hunting big game required more than spears and courage. In addition, Pickering stresses the need for emotional control: coolness, grace under pressure, the proper combination of strategy and stealth. He also suggests that the capacity to organize and manage aggression played a role within pre-human society, by obliging members to keep the group’s well-being in mind. An excessively greedy or violent leader might not last for long: the skills required to sneak up on and kill a buffalo could be turned to political uses.

Given how contentious the field seems to be (the title Rough and Tumble clearly refers to paleontologists as much as to prehistoric society) it will be interesting to see how Pickering’s colleagues respond to the book. As a layman, I can only say that it was fascinating and thought-provoking. And that, all things considered, I’d rather be a bonobo.

Faculty who teach online are invisible on campuses (essay)

Over the past five or six years, as I walked the halls or stepped into the faculty mailroom, copy room, and faculty/staff lounge at the community college where I teach, I have been struck by the noticeable absence of faculty.  And I don’t mean part-time faculty, who -- despite making up nearly 70 percent of all community college faculty -- have always been nearly invisible on campus.

I mean full-time faculty. Simply stated, they’re just not around as much anymore.

What’s changed? The growing number of full-time faculty teaching courses offered entirely online.

At my college, several faculty teach entirely online and, other than professional development days, are rarely on campus. More typical is the full-time faculty member who now teaches one, two or three courses of his or her five-course teaching load online. (I myself don’t teach online, for reasons I’ll explain later.) While not completely absent from campus, these faculty aren’t nearly as present as they were when I began teaching 28 years ago.

The connection between teaching online and being off-campus hit home when I asked a friend who teaches full time and entirely online at a community college in Illinois about a department colleague.  He replied he hadn’t seen his colleague in a year and thought perhaps he was on medical leave. It turned out that the colleague wasn’t on medical leave, but rather was teaching entirely online. The two never saw each other and were now more like independent contractors than department colleagues.

Whether community college faculty is teaching online effectively and students are learning remains open to debate.  In its “Research Overview: What We Know About Online Course Outcomes,” the Community College Research Center reports that ”online course taking was... negatively associated with course persistence and completion”; and that “lower performing students” — the very type of students enrolling in community colleges — fared worse in online courses as compared to face-to-face courses.  Faculty who teach online at my college report similar findings.

But it’s not higher attrition rates that worry me about teaching online. What worries me, and what’s not open to debate, is the dwindling presence of faculty on campus, which is particularly troubling for community college students, who now have even fewer opportunities to interact with faculty and students inside and outside the classroom. 

Why does faculty presence on campus matter?

Community colleges are typically commuter schools. Students arrive on campus, attend classes (often scheduled two days a week), and leave. Yet research on community college students finds that student engagement with faculty and fellow students inside and outside the classroom is crucial to student retention and academic success. The 2008 Community College Survey of Student Engagement found that “[d]ata consistently show that students are more engaged in the classroom than anywhere else” (my emphasis).

According to Kay McClenney, director of the Center for Community College Student Engagement, “[r]esearch shows that the more actively engaged students are — with college faculty and staff, with other students, and with the subject matter they study — the more likely they are to learn, to stick with their studies, and to attain their academic goals.” The Pearson Foundation’s 2010 Community College Survey found that “[t]wo-thirds of students believe that in order to succeed in community college, it is extremely or very important to have access to academic advisors and to establish relationships with professors.”

It’s not surprising, then, to learn that community colleges that rely heavily on part-time faculty have higher attrition rates and lower graduation rates — part-time faculty have (even) fewer opportunities to engage with students. In short, student engagement with other students and faculty on a community college campus promotes retention and academic success.

One of my students described the importance of classroom-based interaction in a course evaluation. “My mindset was that it was just going to be another English class, and I was not going to try my hardest or get much out of it.  I was taking it as a class that I needed to get out of the way for my program of interest.  As time went on I realized how into teaching you were and that the people in the classroom really wanted to learn and to get something out of the class.  I then decided that maybe I should apply myself and that was the best choice I made the whole semester.”

It’s highly unlikely this student would have had a similar realization in an online course that offered no face-to-face interaction.

When I reflect on my undergraduate education, face-to-face interaction with faculty had profound effects. I can’t imagine James Woodress, my American literature professor, having such a powerful and positive influence on my life, if, as a student at the University of California at Davis, I hadn’t taken his English courses in a classroom, and if I hadn’t gotten to know him inside and outside the classroom.  I have watched the poet Gary Snyder on YouTube, and as good and as interesting as that is, it doesn’t compare to the experience of being in a classroom with him.

Community college students often state they take courses online for the sake of convenience and/or because of a harried life -- two reasons accepted without debate -- in order to get done with school as quickly as possible. The course becomes merely an obstacle on the path to accumulating credits.

And community colleges -- driven by convenience, economics, and, ironically enough, the completion agenda -- are quick to respond to “customer demand” by offering more and more online courses.

But instead of promoting an online model of education, community colleges should be doing more to keep faculty and students on campus and to foster a classroom and campus-based culture built upon a sense of academic engagement and community.  That may sound outdated and unfashionable, but it’s a model of education that, as research supports, actually increases community college students’ chances of being academically successful.

I will never teach online. As Parker Palmer writes in The Courage to Teach, “I have no wish to learn distanced methods of teaching simply to satisfy students who do not want to relate to me: teaching from afar would violate my own identity and integrity and only worsen the situation.”

I want to be part of an academic community and to teach in a classroom with students whom I get to know so that (as has happened in the past month) when I walk into my local pet store I know the cashier, a current student; or into the pharmacy and I know the tech, a former student; or attend a local concert and I know the musicians, most of whom are former students. I smile every time my wife tells me “we can’t go anywhere without bumping into one of your students.” 

To engender that sense of community requires being present on campus and interacting face to face with my students. That’s not possible with the invisible lives of the online world.
