CEB Committe on Evolutionary Biology

  • Robert Inger, 1920 - 2019: Founding Member of CEB

    Curator Emeritus Robert Inger passed away Friday, April 12, 2019 at age 98. Bob was born in St. Louis, and first developed his interest in reptiles from visits to the St. Louis Zoo. A fortuitous meeting with the zoo’s curator of birds led to a decision to attend the University of Chicago for graduate work, diving right into the world of Asian herps. He was a Lecturer at the University of Chicago from 1958 until his retirement; when the Committee on Evolutionary Biology was formed at U of C in 1968, Bob served on its Executive Committee. 

    Over time, Bob focused his research on the systematics and ecology of reptiles and amphibians of Southeast Asia, with a special emphasis on Sabah and Sarawak, Malaysian states in the Island of Borneo Over the course of his long career, Bob authored or co-authored over 130 peer-reviewed papers and 11 books. He described more than 75 species new to science, and over 40 new species have been named after him by other scientists. 

  • John Bolt, 1940 - 2019

    We announce with sadness the passing of John Ryan Bolt, Emeritus Curator of Fossil Amphibians and Reptiles. John was a leading expert on the evolutionary transformation of fish-like vertebrate animals as they emerged from water and became four-footed tetrapods adapted to life on land. After obtaining a Bachelor’s degree at Michigan State University, John was accepted into the innovative Paleozoology program at the University of Chicago, where he studied with professors and students whose prominence helped define vertebrate paleontology into the early years of the 21st century.  In 1968, after being awarded the first Ph.D. from the Committee on Evolutionary Biology, John taught for a period at the University of Illinois Medical Center before joining the Field Museum in 1972. At the Museum, he built an impressive body of scientific work on early tetrapods, especially fossil amphibians from about 360 to 250 million years ago, and began a wider consideration of vertebrate evolution. For many years, he volunteered as treasurer and later advised on financial oversight for the Society of Vertebrate Paleontology; in 2006, he received the Gregory Award for his dedicated service. Though still working up to the end, he officially retired in 2008, having brought compelling leadership to the Museum and important contributions to the field of vertebrate paleontology. 

     

            This note was written by John's colleagues. A memorial event is being planned.

  • Voight: Enigma: Huge group of octopuses and their eggs where they likely can’t survive

    Enigma: Huge group of octopuses and their eggs where they likely can’t survive.

    "When I first saw the photos, I was like 'No, they shouldn't be there! Not that deep and not that many of them," says Janet Voight, associate curator of zoology at the Field Museum and an author of a new study on the octopuses published in Deep Sea Research Part I.

    Nearly two miles deep in the ocean, a hundred miles off the Pacific coast of Costa Rica, scientists set out on two cruises a year apart to use subsea vehicles to explore the Dorado Outcrop. This rocky seamount made of cooled, hardened lava from an underwater volcano leaks warm fluid from under the earth’s crust. Geochemists went, hoping to sample the warm fluids that emerge from cracks in the rocks; they didn't count on finding dozens of octopus huddled around the cracks near 3000 m depth. The octopus were an unknown species of the genus Muusoctopus--pink, dinner-plate-sized creatures with enormous eyes. Up to a hundred of them seemed to occupy every available rock in a small area. That in itself was strange--Muuscoctopus are normally loners. Stranger still was that nearly all the octopus seemed to be mothers, each guarded a clutch of eggs. And this nursery was centered in the area of warm fluid flow from cracks in the basaltic outcrop.

  • CEB alum Sara Branco featured in the Society for the Study of Evolution’s New Faculty Profiles

    Montana State University is the state’s land grant institution. It creates knowledge and art, and serves communities by integrating learning, discovery, and engagement. The Department of Microbiology and Immunology plays an important role in this mission by providing research, teaching, and service in topics ranging from environmental microbiology, molecular genetics, host-parasite interactions, and disease ecology, to developmental immunology and pathogenicity.
    The Branco Lab studies the ecology and evolution of fungi to further understand the ecological factors that generate and maintain fungal diversity. Specifically, we use a combination of field, laboratory, and computational approaches to investigate how fungi colonize and persist in the environment. Our studies range across biological scales from ecological communities to genomes and genes, emphasizing evolutionary adaptation to hostile environments.
     

  • Benjamin Otoo

    This summer I studied the postcranial anatomy of Whatcheeria. It’s an Early Carboniferous tetrapod, and important because both it’s uniquely primitive for its age and represented by lots of specimens that cover essentially the entire skeleton- almost unheard of for an early tetrapod. Despite consistently being recovered on the tetrapod stem in phylogenetic analyses, it shares a number of skeletal features with the anthracosaurs, a phylogenetically more derived Carboniferous-Permian group that are frequently considered to be amniote relatives. I’m looking forward describing these features with new phylogenetic characters and finding out if they change Whatcheeria’s phylogenetic position and our understanding of early tetrapod relationships. This is part of my research that’s broadly focused on understanding the evolutionary and ecological changes in the aftermath of the end-Devonian extinction 359 million years ago.

  • Jacob Cooper

    My research is focused on the biogeographic aspects of ecology and evolution in birds. I primarily work with birds in Africa, studying relationships across biogeographical barriers of different sizes. While at the University of Chicago, I have received internal funding from the University of Chicago and the Committee on Evolutionary Biology, as well as support from National Geographic, the France Chicago Center, and the Field Museum to perform my dissertation research. This funding has allowed me to perform field work in Cameroon, as well as to visit other museum collections in Belgium, France, Germany, the United Kingdom, and the United States. I also enjoy working with biodiversity data and using it to better understand species’ ecology at different geographic scales. This work has already resulted in one publication while at the University of Chicago (doi:10.1111/jav.01771). I am an advocate for citizen science, and all of my travels (research and otherwise) are logged in the eBird citizen science database.

  • Mariah Wild Scott

    Mariah Wild Scott. I am a PhD student entering my second year.  I am interested in the evolution of life history strategies, specifically related to reproductive effort and maternal input.  Bivalves, including clams and mussels, represent a unique study system for investigating these topics.  Bivalve species have evolved a spectrum of maternal input per offspring and different maternal adaptations to evaluate.  Different life history adaptations that will be compared include free-living, lecithotrophic (yolk-fed), brooded, and parasitic larvae.  Bivalve shells, which provide a record of the animal’s size and shape over the course of its life, also provide the means for unique insight into the impact these costs have on the females.

  • Brooke Weigel Studies Kelp Microbiome

    I am a PhD candidate at the University of Chicago in the Committee on Evolutionary Biology. My research aims to characterize the symbiosis between giant canopy-forming kelp and the millions of tiny bacteria that live on their surfaces. I am determining the identity and functional role of symbiotic bacteria associated with the "bull kelp" Nereocystis luetkeana, which forms extensive underwater forests along the Pacific Coast of the United States and Canada. My research has shown that there are up to 25 million bacteria living on each square centimeter of kelp! Microbial metabolisms may contribute significantly to carbon and nitrogen cycling associated with kelp, which has fueled my desire to characterize the functional importance of this symbiosis. My research has been funded by the Phycological Society of America, National Geographic, and the Committee on Evolutionary Biology.
