Carl Theodore Bergstrom is a theoretical and evolutionary biologist and a professor at the University of Washington in Seattle, Washington, United States. [3] Bergstrom is a critic of low-quality or misleading scientific research. [4] He is the co-author of a book on misinformation called Calling Bullshit: The Art of Skepticism in a Data-Driven World and teaches a class by the same name at University of Washington. [5]
Bergstrom completed his Ph.D. at Stanford University under the supervision of Marcus Feldman [2] in 1998.
Bergstrom's work concerns the flow of information through biological and social networks, [6] as well as the ecology and evolution of pathogenic organisms, including the development of resistance. [7] [8] [9] [10] [11] [12]
He is the coauthor (with Lee Dugatkin) of a college textbook, Evolution. [13] With Jevin West, he developed the popular course and website Calling Bullshit. [14] [15] [16] [17] [18] [19] His work has led to the identification of him as a resource to explain the dynamics of disinformation and misinformation, [20] in general.
In addition to evolutionary biology, Bergstrom's interests include the ranking of scientific journals. In 2007, he introduced the Eigenfactor, [1] metrics for journal ranking. [21] This and related work on open access earned him and his father, Ted Bergstrom, the SPARC Innovator Award in June 2007. [22]
Carl Richard Woese was an American microbiologist and biophysicist. Woese is famous for defining the Archaea in 1977 through a pioneering phylogenetic taxonomy of 16S ribosomal RNA, a technique that has revolutionized microbiology. He also originated the RNA world hypothesis in 1967, although not by that name. Woese held the Stanley O. Ikenberry Chair and was professor of microbiology at the University of Illinois at Urbana-Champaign.
Panarthropoda is a proposed animal clade containing the extant phyla Arthropoda, Tardigrada and Onychophora. Panarthropods also include extinct marine legged worms known as lobopodians ("Lobopodia"), a paraphyletic group where the last common ancestor and basal members (stem-group) of each extant panarthropod phylum are thought to have risen. However the term "Lobopodia" is sometimes expanded to include tardigrades and onychophorans as well.
In taxonomy, the Korarchaeota are a phylum of the Archaea. The name is derived from the Greek noun koros or kore, meaning young man or young woman, and the Greek adjective archaios which means ancient. They are also known as Xenarchaeota. The name is equivalent to Candidatus Korarchaeota, and they go by the name Xenarchaeota or Xenarchaea as well.
Glochidion is a genus of flowering plants, of the family Phyllanthaceae, known as cheese trees or buttonwood in Australia, and leafflower trees in the scientific literature. It comprises about 300 species, distributed from Madagascar to the Pacific Islands. Glochidion species are used as food plants by the larvae of some Lepidoptera species including Aenetus eximia and Endoclita damor. The Nicobarese people have attested to the medicinal properties found in G. calocarpum, saying that its bark and seed are most effective in curing abdominal disorders associated with amoebiasis.
Atlantogenata is a proposed clade of mammals containing the cohorts or superorders Xenarthra and Afrotheria. These groups originated and radiated in the South American and African continents, respectively, presumably in the Cretaceous. Together with Boreoeutheria, they make up Eutheria. The monophyly of this grouping was supported by some genetic evidence.
Robert Kurzban is an American freelance writer and former psychology professor specializing in evolutionary psychology.
The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. As a measure of importance, the Eigenfactor score scales with the total impact of a journal. All else equal, journals generating higher impact to the field have larger Eigenfactor scores.
Scientists trying to reconstruct evolutionary history have been challenged by the fact that genes can sometimes transfer between distant branches on the tree of life. This movement of genes can occur through horizontal gene transfer (HGT), scrambling the information on which biologists relied to reconstruct the phylogeny of organisms. Conversely, HGT can also help scientists to reconstruct and date the tree of life. Indeed, a gene transfer can be used as a phylogenetic marker, or as the proof of contemporaneity of the donor and recipient organisms, and as a trace of extinct biodiversity.
Joseph (Joe) Thornton is an American Biologist. He is a professor at the University of Chicago and a former Early Career Scientist of the Howard Hughes Medical Institute. He is known for resurrecting ancestral genes and tracing the mechanisms by which proteins evolve new functions.
Nancy A. Moran is an American evolutionary biologist and entomologist, University of Texas Leslie Surginer Endowed Professor, and co-founder of the Yale Microbial Diversity Institute. Since 2005, she has been a member of the United States National Academy of Sciences. Her seminal research has focused on the pea aphid, Acyrthosiphon pisum and its bacterial symbionts including Buchnera (bacterium). In 2013, she returned to the University of Texas at Austin, where she continues to conduct research on bacterial symbionts in aphids, bees, and other insect species. She has also expanded the scale of her research to bacterial evolution as a whole. She believes that a good understanding of genetic drift and random chance could prevent misunderstandings surrounding evolution. Her current research goal focuses on complexity in life-histories and symbiosis between hosts and microbes, including the microbiota of insects.
Peter S. Ungar is an American paleoanthropologist and evolutionary biologist.
James A. Lake is an American evolutionary biologist and a Distinguished Professor of Molecular, Cell, and Developmental Biology and of Human Genetics at UCLA. Lake is best known for the New Animal Phylogeny and for the first three-dimensional structure of the ribosome. He has also made significant contributions to understanding genome evolution across all kingdoms of life, including discovering informational and operational genes, elucidating the complexity hypothesis for gene transfer, rooting the tree of life, and understanding the early transition from prokaryotic to eukaryotic life.
Methionine sulfoxide is the organic compound with the formula CH3S(O)CH2CH2CH(NH2)CO2H. It is an amino acid that occurs naturally although it is formed post-translationally.

He mentored over 150 post-doctoral fellows and graduate students from over a dozen disciplines. He was known for his work in molecular imaging of living subjects and early cancer detection.
Microbial phylogenetics is the study of the manner in which various groups of microorganisms are genetically related. This helps to trace their evolution. To study these relationships biologists rely on comparative genomics, as physiology and comparative anatomy are not possible methods.
Bacterial recombination is a type of genetic recombination in bacteria characterized by DNA transfer from one organism called donor to another organism as recipient. This process occurs in three main ways:
The Amphipithecidae were simian primates that lived in Late Eocene and Early Oligocene. Fossils have been found in Myanmar, Thailand, and Pakistan. The limited fossil evidence is consistent with, but not exclusive to, arboreal quadrupedalism. In other words, the species may have moved about in trees on four legs, but not with regular leaping as seen in later simians.
