    Too Much Eukaryote LGT.William F. Martin - 2017 - Bioessays 39 (12):1700115.
    The realization that prokaryotes naturally and frequently disperse genes across steep taxonomic boundaries via lateral gene transfer gave wings to the idea that eukaryotes might do the same. Eukaryotes do acquire genes from mitochondria and plastids and they do transfer genes during the process of secondary endosymbiosis, the spread of plastids via eukaryotic algal endosymbionts. From those observations it, however, does not follow that eukaryotes transfer genes either in the same ways as prokaryotes do, or to a quantitatively similar degree. (...)

    To What Inanimate Matter Are We Most Closely Related and Does the Origin of Life Harbor Meaning?William F. Martin, Falk S. P. Nagies & Andrey do Nascimento Vieira - 2021 - Philosophies 6 (2):33.
    The question concerning the meaning of life is important, but it immediately confronts the present authors with insurmountable obstacles from a philosophical standpoint, as it would require us to define not only what we hold to be life, but what we hold to be meaning in addition, requiring us to do both in a properly researched context. We unconditionally surrender to that challenge. Instead, we offer a vernacular, armchair approach to life’s origin and meaning, with some layman’s thoughts on the (...)

    Energy for two: New archaeal lineages and the origin of mitochondria.William F. Martin, Sinje Neukirchen, Verena Zimorski, Sven B. Gould & Filipa L. Sousa - 2016 - Bioessays 38 (9):850-856.
    Metagenomics bears upon all aspects of microbiology, including our understanding of mitochondrial and eukaryote origin. Recently, ribosomal protein phylogenies show the eukaryote host lineage – the archaeal lineage that acquired the mitochondrion – to branch within the archaea. Metagenomic studies are now uncovering new archaeal lineages that branch more closely to the host than any cultivated archaea do. But how do they grow? Carbon and energy metabolism as pieced together from metagenome assemblies of these new archaeal lineages, such as the (...)

    A Framework for Understanding Ethical and Efficiency Issues in Pharmaceutical Intellectual Property Litigation.Margaret Oppenheimer, Helen LaVan & William F. Martin - 2015 - Journal of Business Ethics 132 (3):505-524.
    Developing and applying a framework for understanding the complexities of economic and legal considerations in two recent Supreme Court rulings was the focus of this research. Of especial concern was the protection of intellectual property in the pharmaceutical industry. Two cases from 2013 were selected: FTC v. Activis and Association for Molecular Pathology v. Myriad Genetics, Inc.. Part of the rationale for the selection was the importance of the Supreme Court rulings and the importance of the pharmaceutical sector. A qualitative (...)

    Is something wrong with the tree of life?William F. Martin - 1996 - Bioessays 18 (7):523-527.
    A recent study(1) of sequence data from many different proteins has suggested that contemporary prokaryotes and eukaryotes may have shared a common ancestor as recently as 2 billion years ago (the molecular clock). Strong evidence from the geological record, however, indicates that oxygen‐producing microorganisms, perhaps similar to modern cyanobacteria, existed 3.5 billion years ago. The fossil evidence, therefore, suggests that any common ancestor of prokaryotes and eukaryotes must have existed at least 1.5 billion years earlier than suggested by the molecular (...)

    Planctomycetes and eukaryotes: A case of analogy not homology.James O. McInerney, William F. Martin, Eugene V. Koonin, John F. Allen, Michael Y. Galperin, Nick Lane, John M. Archibald & T. Martin Embley - 2011 - Bioessays 33 (11):810-817.
    Planctomycetes, Verrucomicrobia and Chlamydia are prokaryotic phyla, sometimes grouped together as the PVC superphylum of eubacteria. Some PVC species possess interesting attributes, in particular, internal membranes that superficially resemble eukaryotic endomembranes. Some biologists now claim that PVC bacteria are nucleus‐bearing prokaryotes and are considered evolutionary intermediates in the transition from prokaryote to eukaryote. PVC prokaryotes do not possess a nucleus and are not intermediates in the prokaryote‐to‐eukaryote transition. Here we summarise the evidence that shows why all of the PVC traits (...)

    Of early animals, anaerobic mitochondria, and a modern sponge.Marek Mentel, Mayo Röttger, Sally Leys, Aloysius G. M. Tielens & William F. Martin - 2014 - Bioessays 36 (10):924-932.
    The origin and early evolution of animals marks an important event in life's history. This event is historically associated with an important variable in Earth history – oxygen. One view has it that an increase in oceanic oxygen levels at the end of the Neoproterozoic Era (roughly 600 million years ago) allowed animals to become large and leave fossils. How important was oxygen for the process of early animal evolution? New data show that some modern sponges can survive for several (...)

    University Mission Statements and Sustainability Performance.Yvette P. Lopez & William F. Martin - 2018 - Business and Society Review 123 (2):341-368.
    This paper examines the relationship between university mission statements and sustainability practices by institutions of higher education. We examine mission statement constructs and the degree to which higher educational institutions meet specific sustainability criteria in line with the College Sustainability Report Card. Our sample consists of 347 universities from the Sustainable Endowment Institute's (2011) Green Report Card. Previous research suggests that mission statements are essential for superior organizational performance outcomes. We examine the relationship between university mission statement content and sustainability (...)
