Dr. Andrew Herbert Knoll has changed the way we think about our planet's history. His research combines field and laboratory studies, integrating evolutionary insights from the fossil record with data on environmental history gleaned from chemical analyses of ancient sedimentary rocks. He is especially well known for his reconstruction of life's early history (actually the first 85% of biological history, culminating in the Cambrian radiation of animals).
Dr. Knoll's early field research in the glaciated mountains of Spitsbergen revealed exceptionally preserved fossils of both cyanobacteria and eukaryotic microorganisms. Interpreting them in light of environmental variability, taphonomy (changes that accompany post mortem decay), and comparative biology, Dr. Knoll and his students established the template for modern studies of Earth's early fossil record. Again focusing on Spitsbergen rocks, Dr. Knoll and John Hayes were the first to analyze Proterozoic biogeochemistry in the context of measured stratigraphic sections, establishing both the unusual behavior of Earth's carbon cycle just before the rise of animals and the utility of chemical stratigraphy for correlating ancient sedimentary rocks. With Chinese colleagues, Dr. Knoll illuminated the exceptional diversity of eukaryotic organisms in ca. 600-580 million year old phosphatic rocks from China, documenting both complex multicellular algae and populations interpreted as animal diapause cysts, eggs and early cleavage stage embryos. In 730 million year old rocks from the Grand Canyon, Arizona, Dr. Knoll and his students documented the oldest unambiguously heterotrophic protists -- vase-shaped microfossils of Amoebozoa, a major branch of the eukaryotic tree. And in 1500-1400 million year old shales from Australia, they uncovered an exceptional record of early eukaryotic diversity in the oceans. Coordinated analyses of iron and sulfur chemistry in the same rocks provided the first empirical confirmation of the hypothesis that in Proterozoic oceans, surface waters contained oxygen, but subsurface water masses commonly did not.
Dr. Knoll has also integrated fossils and environmental history in studies of Phanerozoic evolution, commonly using physiology to connect the two. With Sean Carroll, he wrote a pioneering paper interpreting early animal fossils in light of both late Proterozoic environmental change and then-emerging insights from molecular development. With his students, Dr. Knoll also brought developmental biology to bear on the evolution of leaves in early vascular plants and applied physiological models to quantify fluid flow in Paleozoic seed plants. And with Karl Niklas and Bruce Tiffney, Dr. Knoll published the first papers to quantify vascular plant diversity through time. Additionally, Dr. Knoll has documented changes through time in the composition of marine phytoplankton and used insights from physiological ecology to show how changes in primary producers illuminate the broader evolutionary history of marine ecosystems. Dr. Knoll also introduced a novel approach to understanding mass extinction by demonstrating that rapid increases in carbon dioxide could account for observed selectivity in end-Permian mass extinction. More generally, Dr. Knoll argued that rapid increase in carbon dioxide, ocean acidification, and oxygen depletion in subsurface waters went hand in hand during the end-Permian biological crisis, an observation that resonates with concerns about 21st century global change.
Dr. Knoll has brought his insights about planetary history to the study of Mars, working as part of the science team for NASA's MER rover mission. Among other things, Dr. Knoll and his colleagues showed while minerals found in ancient sediments at Meridian planum required water for their formation, as ambient waters evaporated, water activity reached levels that would challenge all known life on Earth.
In general, then, Dr. Knoll has integrated insights from paleontology, stratigraphy, geochemistry, and comparative biology to build an understanding of Earth (and planetary) history that underscores the dynamic interactions between life and environment across the broad sweep of geologic time.
