  • Neandertal night on PBS

    Tue, 2013-05-14 09:34 -- John Hawks

    This Wednesday (May 15) is Neandertal night on PBS stations in the U.S., with two documentary programs covering the last few years of science about these ancient people.

    First, the NOVA episode this week is the "Decoding Neandertals" program. This was broadcast earlier this year, and it is a really good summary of some current research into Neandertal genetics and behavior:

    Over 60,000 years ago, the first modern humans—people physically identical to us today—left their African homeland and entered Europe, then a bleak and inhospitable continent in the grip of the Ice Age. But when they arrived, they were not alone: the stocky, powerfully built Neanderthals had already been living there for hundred of thousands of years. So what happened when the first modern humans encountered the Neanderthals? Did we make love or war? That question has tantalized generations of scholars and seized the popular imagination. Then, in 2010, a team led by geneticist Svante Paabo announced stunning news. Not only had they reconstructed much of the Neanderthal genome—an extraordinary technical feat that would have seemed impossible only a decade ago—but their analysis showed that "we" modern humans had interbred with Neanderthals, leaving a small but consistent signature of Neanderthal genes behind in everyone outside Africa today. In "Decoding Neanderthals," NOVA explores the implications of this exciting discovery. In the traditional view, Neanderthals differed from "us" in behavior and capabilities as well as anatomy. But were they really mentally inferior, as inexpressive and clumsy as the cartoon caveman they inspired? NOVA explores a range of intriguing new evidence for Neanderthal self-expression and language, all pointing to the fact that we may have seriously underestimated our mysterious, long-vanished human cousins.

    Second, a new episode of Secrets of the Dead is being broadcast, titled "Caveman Cold Case", about El Sidron Cave:

    A tomb of 49,000 year-old Neanderthal bones discovered in El Sidron, a remote, mountainous region of Northern Spain, leads to a compelling investigation to solve a double mystery: How did this group of Neanderthals die? And, could the fate of this group help explain Neanderthal extinction? Scientists examine the bones—buried over 65 feet below ground—and discover signs that tell a shocking story of how this group of six adults, three teenagers, two children and a baby may have met their death. Some bones have deep cuts, long bones are cracked and skulls crushed—distinct signs of cannibalism. Was it a result of ritual or hunger? Neanderthal experts are adamant that they were not bloodthirsty brutes. Will this investigation challenge their views? What happened here 49000 years ago will take us on a much bigger journey—from El Sidron to the other end of the Iberian Peninsula where scientists are excavating beneath the seas off Gibraltar in search of Neanderthal sites. Scientists working here had theories—but no proof—for why Neanderthals went extinct. El Sidron may change this.

    I'm really excited that this one is being broadcast in the U.S. -- it covers the science from a forensic point of view, including new insights about diet and breadth of behavior. It is a great program that goes into the research by Antonio Rosas and Carles Lalueza-Fox on the Spanish Neandertals, and gives us a viewpoint on the Gibraltar Neandertals with Clive Finlayson.

    I play a small part in both programs, and I'm happy to see the Neandertals getting such high-profile attention!

  • Announcing my MOOC, Human Evolution: Past and Future

    Mon, 2013-04-01 15:54 -- John Hawks

    I have begun a project that may change the way we teach and communicate the science of human evolution. Starting in January, 2014, I will be offering a massive open online course titled, "Human Evolution: Past and Future".

    This course and all its materials will be open and free for anyone, anywhere in the world. As of this moment, more than 6500 people have already signed up for the course. The course is still more than nine months away, and I'll be developing materials across the entire time up through January.

    Developing this course is a huge investment for me. My institution, the University of Wisconsin-Madison, is making it possible -- but at the same time I'm actively seeking out partnerships and sponsors. I'll be documenting the development process here on the blog, and in a series of presentations and publications as I go. Massive open online courses (MOOCs) have begun to change the way universities approach online education, and the course will be a research platform as well as an educational experience.

    What will be new in this course:

    Expert interviews. I'll be assembling and curating a series of filmed interviews with experts in paleoanthropology to talk about their work. Why should students hear me describe other people's work, when I can engage the scientists themselves? I've already begun these interviews, and will be adding more than thirty by the time the course begins.

    Mini-documentaries. To the extent possible, I'll be virtually taking students to the field, into the laboratory, and giving first-hand experiences with the materials of human evolution. That means many of my video presentations will be much more like short documentary productions than lectures. My priority is making the real materials as available as possible.

    Guided laboratories. We'll be exploring genome data, providing some excellent virtual laboratories with the fossil evidence, and running experiments with evolutionary change.

    Participatory science. With a worldwide group of thousands of students, we'll be giving people the opportunity to participate in some real research. Some will be as simple as massive measurements of body proportions. Others will be more involved, leading us to...

    Looking to the future. The course title is "Human Evolution: Past and Future." To me, the path of our evolution in the past is closely tied to where our species may be going. To that end, the course will be looking at the next hundred, thousand and ten thousand years of our evolution. I'll be interviewing people who are thinking about the impact of technology on our future evolution, and students will come up with their own scenarios based on a strong understanding of the forces that shaped human evolution in the past.

    I'm doing this because human evolution is important. The effects of the past shape who we are today, our health and choices, our societies and imaginations. Anthropology can engage people in their own lives and experience. The MOOC technology platform has such potential for innovating new forms of education, I am eager to bring human evolution into that space.

    And who wouldn't jump at the opportunity to reach tens of thousands of people looking for information about our evolution? Some people really don't like the word, MOOC. All I have to say is, I got used to "blog", so why not another strange word? This is a natural extension to what I've been doing for nine years here on my blog: curating and writing reactions to the best research in paleoanthropology. In this project, I'll be able to bring people virtually out to the field, and let experts tell about their findings in their own words.

    What you can do:

    Sign up for the course. I encourage everybody to sign up! You don't have to finish a MOOC, or even watch all the materials, to get a lot out of it. My MOOC will allow you to "choose your own adventure" to the maximum extent possible. If you want a strong module on ancient diets, you can get that by itself, or together with my best materials on Neandertal genetics and post-agricultural evolution.

    Look for your opportunity to help. I'm working on several partnerships for this course, and the most important one is with you. With a worldwide group of students, many from developing economies, I cannot assign a traditional textbook. I need a free version of everything written for the students in the course, and that means I'll be providing the text myself. I'll be providing some opportunities to help support this important cause, which will impact students everywhere.

    Adopt the materials. We're putting a lot of work into the materials for the course. A lot of professionals are donating time to be interviewed, and are allowing me to use photos and other materials to make a really high-quality presentation. I want to get these high-quality materials into as many classrooms as possible. If you're teaching human evolution in a college or high school setting, look out for additional information on how to use materials and develop curriculum that works in your context!

    I learned a lot from my experiment last year putting lectures online from my regular course. I am putting those insights together with discoveries from other MOOC experiments to create new ways for students to network with each other and with ongoing science. This is just the initial announcement. As the summer progresses, I'll be giving you more background about how I'm producing the course, along with sample materials and some chances to participate. I'm looking forward to the experiment, and I hope you will follow on the journey.

    I will be teaching a new massive open online course, starting in January 2014
  • "Decoding Neanderthals" to be broadcast

    Sat, 2012-12-22 16:08 -- John Hawks

    NOVA on American PBS stations has produced a new documentary about Neandertals: "Decoding Neanderthals". They have just announced that it will be broadcast January 9 on most stations.

    Here's the program description:

    Over 60,000 years ago, the first modern humans—people physically identical to us today—left their African homeland and entered Europe, then a bleak and inhospitable continent in the grip of the Ice Age. But when they arrived, they were not alone: the stocky, powerfully built Neanderthals had already been living there for hundred of thousands of years. So what happened when the first modern humans encountered the Neanderthals? Did we make love or war? That question has tantalized generations of scholars and seized the popular imagination. Then, in 2010, a team led by geneticist Svante Paabo announced stunning news. Not only had they reconstructed much of the Neanderthal genome—an extraordinary technical feat that would have seemed impossible only a decade ago—but their analysis showed that "we" modern humans had interbred with Neanderthals, leaving a small but consistent signature of Neanderthal genes behind in everyone outside Africa today. In "Decoding Neanderthals," NOVA explores the implications of this exciting discovery. In the traditional view, Neanderthals differed from "us" in behavior and capabilities as well as anatomy. But were they really mentally inferior, as inexpressive and clumsy as the cartoon caveman they inspired? NOVA explores a range of intriguing new evidence for Neanderthal self-expression and language, all pointing to the fact that we may have seriously underestimated our mysterious, long-vanished human cousins.

    I make an appearance on the show -- and that's my voice in the trailer talking about the "mother of all public relations problems" that Neandertals have faced.

  • Hawks lectures at the University of Alabama, December 6 and 7

    Sun, 2012-12-02 17:05 -- John Hawks

    I will be traveling south this week to give a pair of lectures at the University of Alabama. On Thursday night, I will be giving a lecture in the ALLELE (ALabama LEctures on Life’s Evolution) seminar series. The lecture will be in the Biology Building Auditorium (room 127) at 7:30 pm. This is a big public lecture, and if you're in the area, I encourage you to come.

    The title is "Neandertime: How Ancient Genomes are Transforming our Past and Present". I'll be reviewing the science of Neandertals and Denisovans, some of the work we've been doing here in our research group on these ancient people, and how ancient genomes are beginning to yield new insights about the biology of living people.

    The ALLELE lectures are really one of the premier lecture series in biology, anywhere in the world. For some perspective, Christopher Lynn reviewed last year's ALLELE lectures in a post on EvoS, with a great list of wonderful speakers. It's really humbling for me to be included on this year's list, along with two other prominent scientists and a humanist engaged with evolutionary biology including Edward O. Wilson, Bruce MacFadden and Joe Carroll. The interdisciplinary evolution perspective is something we try to promote here at the University of Wisconsin-Madison, because it's a great way to explore commonalities and threads of connections that deepen others' engagement in our evolutionary history.

    On Friday afternoon, I'll be giving a smaller lecture for the Anthropology Department, on human evolution during the Holocene. That lecture is at 3:00 pm in ten Hoor Hall, room 22.

    If you're a reader in the area, I hope to meet you there!

  • AAA Meetings watch

    Tue, 2012-11-13 16:54 -- John Hawks

    I will be at the American Anthropological Association meetings in San Francisco for the rest of the week. If you're an anthropologist, I hope to see you there! Remember you can tweet me @johnhawks and I'll be following some of the sessions while tweeting on the #aaa2012 hashtag.

    I will be participating in an exciting podium session on Saturday afternoon, organized by Jamie Clark and Adam Van Arsdale. Adam has a list of the talks in the session, which includes some really great young anthropologists from cultural, archaeological, and biological perspectives.

    Here's my abstract, which is a pretty strong statement of where I think the biological species concept applies to archaic humans:

    Neandertal Genetics: Drawing a New Boundary for Humanity

    John Hawks (University of Wisconsin-Madison)

    Genetic information from ancient skeletons has transformed our understanding of human origins. For more than 160 years, anthropologists defined humanity in contrast to the Neandertals. Now it is clear that the genealogical ties between living people include Neandertals and other archaic humans within our biological species. An accounting of the shared genetic ancestry in humans worldwide and the ancient Neandertal and Denisova genomes helps to show the pattern of population structure in the Middle Pleistocene populations that gave rise to modern humans. Our species included variations that no longer exist today, while our evolution within the last 100,000 years has been a process of amalgamation and rejoining of populations that were once much more different. As we redraw our genealogical boundaries to recognize this pattern of relationships and evolution, we are beginning to discover the way that the present traits of humans around the world emerged in a variable population.

  • Lecture at University of Colorado, Boulder

    Thu, 2012-10-04 21:02 -- John Hawks

    I'll be flying out to Colorado next week for a lecture in Boulder. The lecture is Friday, October 12, at 4:00 pm, in Hale Science 270. I'll be excited to see some friends in Boulder, and if you're in the Boulder area, I'd love to see you there!

  • Gibraltar

    Tue, 2012-09-11 11:57 -- John Hawks

    I've arrived in Gibraltar and am settling down after a fairly long travel. Here's the view to the west toward the Strait.

    Strait of Gibraltar

    I'm here for the Calpé conference on "The Human Niche", and hopefully I'll be able to do a bit of reporting on the proceedings. Meanwhile there are some interesting news items this week including a commentary of mine being released in PNAS, which dovetails incredibly well with a new commentary by Aylwyn Scally and Richard Durbin in Nature Genetics.

    A lower per-generation mutation rate estimate alters much about how we must explain the unfolding of human genetic variation during the last million years. This shift will have some very interesting archaeological and paleontological implications.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
