  • speciation
  • For example, in this course you will use the Howard Hughes Medical Institute's Lizard Evolution Virtual Lab to investigate speciation among anole lizards in the Caribbean Islands. (amnh.org)
  • Concerted evolution is a process that may explain the observation that paralogous genes within one species are more closely related to each other than to members of the same gene family in another species, even though the gene duplication event preceded the speciation event. (wikipedia.org)
  • multicellular
  • A long-standing and pervasive view is that there have been intimate mechanistic links between the evolution of complex life on Earth-in other words, the emergence and ecological expansion of eukaryotic cells and their aggregation into multicellular organisms-and the secular evolution of ocean−atmosphere oxygen levels ( 1 ). (pnas.org)
  • origins
  • Our June issue features bird flocks, the evolution of vertebrae, phenological mismatches, tyrannosaurid origins, Bolivian environmental policy and much more. (nature.com)
  • One of the problems for those studying viral origins and evolution is their high rate of mutation, particularly the case in RNA retroviruses like HIV/AIDS. (wikipedia.org)
  • Distributions
  • It is increasingly recognised that cultural evolution can influence gene distributions in populations, as in the well-known case of the selective effect of dairying on the incidence of adult lactose tolerance. (ucl.ac.uk)
  • epidemiology
  • Although the recent Zika virus (ZIKV) epidemic in the Americas and its link to birth defects have attracted a great deal of attention, much remains unknown about ZIKV disease epidemiology and ZIKV evolution, in part owing to a lack of genomic data. (nih.gov)
  • Viral evolution is an important aspect of the epidemiology of viral diseases such as influenza (influenza virus), AIDS (HIV), and hepatitis (e.g. (wikipedia.org)
  • Rapid
  • Populations of indigenous people in southern Africa carry a gene that causes lighter skin, and scientists have now identified the rapid evolution of this gene in recent human history. (phys.org)
  • Quantum evolution is a component of George Gaylord Simpson's multi-tempoed theory of evolution proposed to explain the rapid emergence of higher taxonomic groups in the fossil record. (wikipedia.org)
  • explain
  • How does evolution work, how does it explain the history of life on Earth, and how is this fundamental concept itself changing in the face of new discoveries? (amnh.org)
  • models
  • One of the main theoretical models applied to viral evolution is the quasispecies model, which defines a viral quasispecies as a group of closely related viral strains competing within an environment. (wikipedia.org)
  • The modern understanding is that the evolution of slopes is much more complex than the classical models of decline, replacement and retreat imply. (wikipedia.org)
  • This focus on using available space at the factory for builder assistance, plus lower sales of the older models, meant there was a good business case for selling off the older designs and freeing space for Evolution completions. (wikipedia.org)
  • time
  • By definition, both will make the patient better in the short term, but we don't know ahead of time which course of action will be best for preventing the evolution of resistance, which leads to more problems in the long term. (psu.edu)
  • human evolution
  • The Journal of Human Evolution concentrates on publishing the highest quality papers covering all aspects of human evolution . (elsevier.com)
  • UCL has one of the one of the largest number of researchers actively involved in human evolution research of any university in the world. (ucl.ac.uk)
  • However, human evolution research is necessarily cross-disciplinary and these researchers are dispersed across a number of different departments and institutes. (ucl.ac.uk)
  • Human Evolution @ UCL provides information on these researchers and their various research themes, as well as on human evolution teaching and seminars, and serves as a focal point for the initiation of collaborative research and teaching. (ucl.ac.uk)
  • work
  • Read, and colleague Troy Day, professor of mathematics, statistics, and biology at Queen's University in Ontario, Canada, developed a very general mathematical model that quantifies the two main evolutionary forces at work in the evolution of drug resistance in disease-causing microbes. (psu.edu)
  • Read
  • Day and Read showed that the optimal approach to combatting the evolution of drug resistance will be either to use the highest dose that is safe or to use the lowest dose that is effective. (psu.edu)
  • high
  • Although quantum evolution may happen at any taxonomic level, it plays a much larger role in "the origin taxonomic units of relatively high rank, such as families, orders, and classes. (wikipedia.org)
  • In September 2003 a French flying team flew an Evolution from Paris to Dakar, making use of the aircraft's high payload to carry all needed supplies. (wikipedia.org)
  • theory
  • The idea of conscious evolution is not a specific theory, but it has loose connections to integral theory, Spiral Dynamics, and noosphere thought. (wikipedia.org)
  • However
  • However, the role that planetary redox evolution has played in controlling the timing of metazoan (animal) emergence and diversification, if any, has been intensely debated. (pnas.org)
  • changes
  • He stated, "there is nothing in the market that can compete with the Evolution" and "unless something drastically changes with the market, after the first of the year, we will be ramping up to one every two weeks. (wikipedia.org)
