THE THIRD CULTURE
---------------------------------------------------

LYNN MARGULIS 1938-2011
"GAIA IS A TOUGH BITCH"

Biologist Lynn Margulis died on November 22nd. She stood out from her colleagues in that she would have extended evolutionary studies nearly four billion years back in time. Her major work was  in cell evolution, in which the great event was the appearance of the eukaryotic, or nucleated, cell — the cell upon which all larger life-forms are based. Nearly forty-five years ago, she argued for its symbiotic origin: that it arose by associations of different kinds of bacteria. Her ideas were generally either ignored or ridiculed when she first proposed them; symbiosis in cell evolution is now considered one of the great scientific breakthroughs.

Margulis was also a champion of the Gaia hypothesis, an idea developed in the 1970s by the free lance British atmospheric chemist James E. Lovelock. The Gaia hypothesis states that the atmosphere and surface sediments of the planet Earth form a self- regulating physiological system — Earth's surface is alive. The strong version of the hypothesis, which has been widely criticized by the biological establishment, holds that the earth itself is a self-regulating organism; Margulis subscribed to a weaker version, seeing the planet as an integrated self- regulating ecosystem. She was criticized for succumbing to what George Williams called the "God-is good" syndrome, as evidenced by her adoption of metaphors of symbiosis in nature. She was, in turn, an outspoken critic of mainstream evolutionary biologists for what she saw as a failure to adequately consider the importance of chemistry and microbiology in evolution.

I first met her in 1995 when I interviewed her for my book The Third Culture: Beyond the Scientific Revolution (1995). Below, in remembrance, please see her chapter, "Gaia is a Tough Bitch". One of the compelling features of The Third Culture was that I invited each of the participants to comment about the others. In this regard, the end of the following chapter has comments on Margulis and her work by Daniel C. Dennett, the late George C. Williams, W. Daniel Hillis, Lee Smolin, Marvin Minsky, Richard Dawkins, and the late Francisco Varela. Interesting stuff.

As I wrote in the introduction to the first part of the book (Part I: The Evolutionary Idea): "The principal debates are concerned with the mechanism of speciation; whether natural selection operates at the level of the gene, the organism, or the species, or all three; and also with the relative importance of other factors, such as natural catastrophes." These very public debates were concerned with ideas represented by George C. Williams and Richard Dawkins on one side and Stephen Jay Gould and Niles Eldredge on the other side. Not for Lynn Margulis. All the above scientists were wrong because evolutionary studies needed to begin four billion years back in time. And she was not shy about expressing her opinions. Her in-your-face, take-no-prisoners stance was pugnacious and tenacious. She was impossible. She was wonderful.  

[ED NOTE: I am asking participants in "The Third Culture" as well as other interested Edgies for comments which we will post as they are received.]

LYNN MARGULIS was Distinguished University Professor in the Department of Geology at the University of Massachusetts, Amherst. She was the author of Symbiotic Planet, The Origin of Eukaryotic Cells,Early Life, and Symbiosis in Cell Evolution. She was also the coauthor, with Karlene V. Schwartz, ofFive Kingdoms: An Illustrated Guide to the Phyla of Life on Earth and with Dorion Sagan of Acquiring Genomes, Microcosmos, Origins Of Sex, and Mystery Dance.

THINKING ABOUT THE UNIVERSE ON THE LARGER SCALES
Raphael Bousso
Edge Video (38 minutes)

Introduction
by Leonard Susskind

Andrei Linde had some ideas, Alan Guth had some ideas, Alex Vilenkin had some ideas.  I thought I was coming in with this radically new idea that we shouldn't think of the universe as existing on this global scale that no one observer can actually see, that it's actually important to think about what can happen in the causally connected region to one observer, what can you do in any experiment that doesn't actually conflict with the laws of physics, and require superluminal propagation, that we have to ask questions in a way that conform to the laws of physics if we want to get sensible answers.

RAPHAEL BOUSSO, Professor of Physics at the university of California, Berkeley, is recognized for discovering the general relation between the curved geometry of space-time and its information content, known as the "holographic principle." This principle is believed to underlie the unification of quantum theory and Einstein's theory of gravity. Bousso is also

Paleontologist and sustainability advocate Bill Berry dies at 79

Paleontologist and sustainability advocate Bill Berry dies at 79: "

Paleontologist William B. N. Berry was a world expert on extinct, 400 million-year-old sea creatures, but he will be perhaps best remembered in the Bay Area as a champion of sustainability and for instilling in his students a concern for the local ecology.


A former director of UC Berkeley’s Museum of Paleontology and a professor of earth and planetary science who served the campus for 53 years, Berry died May 20 of skin cancer and related complications. He was 79.


Berry encouraged his students to get involved in Save the Bay and Save Strawberry Canyon, and always included in his twice yearly introductory environmental class a cleanup of Strawberry Creek, which runs through the campus. He led his undergraduate students in landmark restoration studies of the Tennessee Hollow Watershed in the Presidio of San Francisco, and an environmental studies program he helped launch at the city’s Galileo High School began restoration in the area before the U.S. National Park Service took up the project.


Students in Berry’s environmental science classes went on to promote recycling and waste reduction on campus and were instrumental in pushing the UC system to adopt an aggressive sustainability policy.


In 2005, he was honored at a campus-wide Sustainability Summit for “exploring environmental issues with generations of UC Berkeley students” and “giving students the tools and inspiration to think about problems from a sustainability standpoint and fostering a culture of sustainability and forward-thinking design.”


“In his research, his teaching and his service, the unifying theme was getting out into the natural world to observe, measure and analyze,” said colleague Carole Hickman, a UC Berkeley paleobiologist and geologist who is now a Professor of the Graduate School in the Department of Integrative Biology. “His colleagues and students remember him fondly for his enthusiasm for ‘hands-on’ science, whether collecting graptolites in the Ordovician or assessing water quality in an urban stream.”


Building a sustainable campus


In the mid-2000s, Berry sought out campus recycling manager Lisa Bauer for help retooling an undergraduate environmental studies class to focus on how students can actively work toward a sustainable society, and in the process doubled its enrollment. Freshman and sophomore seminars he taught became a “seed bed for student sustainability,” Bauer said.


“Bill got it, that the voice people are going to listen to is that of the students,” she said. “Bill was really brilliant in planting the seed, watering it and letting it grow. And it happened. The campus now has a robust sustainability ethic. We have a director of sustainability, regular sustainability summits, a Chancellor’s Advisory Committee on Sustainability. The campus has incorporated into its fabric the things that Bill was working on initially.”


Berry was born in Boston on Sept. 1, 1931, raised in Arlington, Mass., and attended Harvard University, from which he earned an A.B. in 1953 and an A.M. in 1955. While an undergraduate, he was told by geology professor Harry Whittington that nobody in North America was working on graptolites, an extinct group of animals abundant in the world’s oceans between 500 and 400 million years ago. Whittingon suggested that these fossilized animals would be a good subject for a Ph.D. dissertation, and Berry took the advice and started work on graptolites at Yale University. Shell Oil became interested in the stratigraphic aspects of Berry’s studies and funded field work in Texas. When he completed his Ph.D. in 1957, Berry taught for a year at the University of Houston before coming to UC Berkeley in 1958.


Berry’s research on graptolites shed important light on ancient environments, the precise age and correlation of rocks, the processes of evolution and extinction, and the positions of ancient continents and ocean basins, Hickman said.


“As a paleontologist, he was interested in describing the genera and species of graptolites, but he also used these graptolites to figure out the relative ages of Silurian beds around the world,” said former colleague Arthur J. Boucot, a distinguished professor of zoology at Oregon State University in Corvallis. With Boucot focusing on the fossilized seashells of brachiopods and Berry working on graptolites, the pair assembled over a period of three decades Silurian correlation charts that are the basis for more precise charts used by geologists, paleontologists and even oil exploration companies today when dealing with 400- to 440-million-year-old rock.


Berry held a Guggenheim Fellowship at Cambridge University, where he worked on the evolution of Silurian graptolites. His work led to more than 300 published papers, abstracts and books. Over the course of his career, he was an invited panelist, consultant, advisor and organizer at conferences on climate change and urban and environmental planning in California, as well as nationally and internationally.


“I was always amazed at how productive he was and how many things he kept going. He was the ultimate multitasker,” said Doris Sloan, a retired paleontologist who received her Ph.D. at UC Berkeley under Berry and who taught environmental sciences courses for many years on campus.


Paleontologist as both biologist and geologist


Berry served as chair of the Department of Paleontology from 1975 until 1987. At the time, the department was the only free-standing paleontology department in the country. The curriculum trained students equally in geology and biology and required majors and graduate students to acquire expertise in the history of both marine and terrestrial life and in the separate subdisciplines of vertebrate paleontology, invertebrate paleontology, micropaleontology, paleobotany and biostratigraphy.


“During his 33 years in the department, Berry served as an exemplar of the paleontologist as neither biologist nor geologist, but as both,” Hickman said. “His 1968 book, ‘Growth of a prehistoric time scale based on organic evolution,’ served for many years as a supplementary text for courses in introductory geology, evolution, paleontology, stratigraphy, and philosophy and history of science.”


Berry also served as director of the Museum of Paleontology from 1976 until 1987, and as director of the Environmental Sciences Program from 1979 to 1993. During his 12 years as director of the paleontology museum, he broadened its mission by instituting public outreach programs that included collaborations with the Lawrence Hall of Science, participation in a popular annual campus-wide open house, public lectures and visits to local schools.


When the paleontology department was split up in 1989, Berry elected to transfer to the Department of Geology and Geophysics, which eventually became the Department of Earth and Planetary Science (EPS).


“He put real effort into his work with students, and his courses attracted non-majors as well as majors,” Hickman said. “He was one of those professors who enjoyed teaching very large undergraduate classes numbered in the hundreds, as well as smaller, more specialized classes for advanced students.”


In 2010, he taught or mentored more than 1,000 students in EPS – one course enrolled more than 500 students – and nearly 600 more in environmental sciences. It was joked that he taught more students than all the other faculty members of the EPS department combined, said EPS chair Roland Burgmann.


Berry served on numerous campus committees, including for seven years on the committee that allocated space and reviewed planned construction projects. He also chaired the committee that produced UC Berkeley’s Long Range Development Plan in 1988-91.


His favorite committee, however, was the one that awarded undergraduate scholarships such as the Regents’ and Chancellor’s Scholarships, which are given for academic merit. As a member of the committee since 1996, he would find faculty to review more than 2,000 applications each year, and would personally interview hundreds of candidates. His concern about affordability and the need to reward excellence led him to urge more private fundraising to support undergraduate scholarships.


His service extended into the Berkeley community, where he represented UC Berkeley at Berkeley City Council meetings and planning committee meetings. Berry also worked with the United States Geological Survey and held an appointment in the Applied Sciences Division of the Lawrence Berkeley National Laboratory.


Berry was elected a Fellow National of The Explorers Club in 1979. In 1960, he was made a Life Member of the Norwegian Geological Society, and was a member of the General Society Sons of the Revolution, an organization of descendants of those who fought in the Revolutionary War. An avid sports fan, he liked to sit in the sunny student section of Memorial Stadium during Cal football games, was eager to accommodate the schedules of sports team members in his classes, and advised women’s crew for several years.


Berry is survived by his wife of 50 years, Suzanne Spaulding Berry, and son Bradford B. Berry, both of Berkeley.


No memorial service is planned. Donations may be sent to the William B. N. Berry Memorial Research Fund to support graduate students in invertebrate paleontology. Checks can be made payable to the “William B. N. Berry Memorial Research Fund” and sent to the Museum of Paleontology, University of California, Berkeley, 1101 Valley Life Science Building, Berkeley, CA 94720-4780.

The power of the Web

I was crawling the Web recently researching one of my favorite creatures, the American mastodon (Mammut americanum) when I ran across a news article published in the New York Times in 1980 describing a skull discovered in a Pleistocene river gravel deposit here in Santa Cruz.  Funny thing: it was the very skull that I spent two years preparing while working at the Santa Cruz City Museum of Natural History!  I thought it sounded a bit familiar.   How very interesting that life circles back upon itself when we least expect it.

Patterns and inferences...

I remain inspired by how our minds can abstract, interpolate, and conceptualize large amounts of seemingly random information.  Often when I show this specimen to students who have never seen a whale skull, let alone one entombed in rock and then cut away in cross-section, I get the most curious, and often engaging, looks!  We should keep our sense of wonder and curiosity fresh and at the fore in our daily activities.

A Cetacean rib excavation & sunset for the New Year

We discovered the fossilized rib of a cetacean and spent our time intently concentrating back and forth between the beautiful bone and a wonderful sunset.  The rib was extracted as a single intact unit.  The sun eluded our capture and dissappeared into the grasp of the Winter evening.
