• organisms
  • Biological organisms are highly complex and are comprised of many different parts that function together to ensure the survival and reproduction of the whole. (eurekalert.org)
  • Understanding how the division of labor evolved in multicellular organisms is difficult because single cells are expected to act selfishly to protect their own existence instead of working cooperatively to achieve a more productive higher level of organization, explains author Sergey Gavrilets, Associate Director for Scientific Activities at the National Institute for Mathematical and Biological Synthesis and a professor at the University of Tennessee-Knoxville. (eurekalert.org)
  • Many biologists used to believe that evolution was progressive and had a direction that led towards so-called "higher organisms," despite a lack of evidence for this viewpoint. (wikipedia.org)
  • With selection, evolution can also produce more complex organisms. (wikipedia.org)
  • Indeed, some computer models have suggested that the generation of complex organisms is an inescapable feature of evolution. (wikipedia.org)
  • Evolution of metal ions in biological systems refers to the incorporation of metallic ions into living organisms and how it has changed over time. (wikipedia.org)
  • In particular, Auletta is interested in the relevance of notions like information control, functional equivalence class, formal constraints and top-down causation as to the organisms' capability of dealing with a challenging environment at the ontogenetic and epigenetic levels, eventually leading to the emergence of new biological functionalities at the phylogenetic level. (wikipedia.org)
  • mechanisms
  • Cultural evolution, the domain of research focused on how culture changes through time due to different individual transmission mechanisms and population-level effects, often uses models derived from population genetics, in which agents are passive recipients of cultural traits (e.g. (wikipedia.org)
  • fossil
  • This unique system also explains how major groups of animals rapidly appeared in the Cambrian explosion, and why so much history about evolution is missing from the fossil records. (physicsessays.org)
  • natural selection
  • Everybody wants to say that evolution is equivalent to natural selection and that things that are sophisticated and complex have been absolutely selected for," said study co-author Ariel Fernández, PhD, a visiting scholar at the University of Chicago and senior researcher at the Mathematics Institute of Argentina (IAM) in Buenos Aires.

  • Particular
  • Indeed, as for all comparative methods, phylogenetic methods can integrate information from multiple genomes, and in particular integrate them using a model of evolution. (wikipedia.org)
  • conference
  • We also would like to draw your attention that the 10th AIMS Conference on Dynamical Systems, Differential Equations and Applications ( http://www.icmat.es/congresos/aims2014/ ) will be held in Madrid, Spain, from July 7 to 11, 2014, immediately after the CRM Workshop on Virus Dynamics and Evolution. (crm.cat)
  • systems
  • Metal ions have been associated with biological systems for billions of years, but only in the last century have scientists began to truly appreciate the scale of their influence. (wikipedia.org)
  • His main interests in quantum information led him to focus his further research on the way in which biological and cognitive systems deal with information. (wikipedia.org)
  • This pathway of research eventually led him to consider quantum information as a fruitful approach for studying the way in which biological and cognitive systems deal with information at all scales. (wikipedia.org)
  • years
  • Over four billion years of evolution, plants and animals grew far more complex than their single-celled ancestors. (redorbit.com)
  • role
  • Polanyi emphasized the important role of information in biological phenomena but considered this notion as something alien to physics 3 . (springer.com)
  • Thought
  • I hope that it causes us to pause and think about how evolution operates in new ways that we haven't thought about before. (redorbit.com)
  • Please
  • Please note that from June 30 to July 4, 2014, that is, immediately after the school, the CRM organises a workshop on Virus dynamics and evolution ( www.crm.cat/2014/WKVirusDynamics ). (crm.cat)
  • events
  • In this setting, the universe follows an infinite cycle of recurring events, while evolution takes place with each consecutive cycle. (physicsessays.org)
  • These serial endosymbiotic transfer events paved the way for evolution of eukaryotic cells, which in turn enabled multicellular assemblages. (blogspot.com)
  • structure
  • One study has suggested that a single ancestral enzyme could have diverged into several families, while another suggests that a stable TIM-barrel structure has evolved through convergent evolution. (wikipedia.org)
  • Zoology (/zuːˈɒlədʒi, zoʊˈɒlədʒi/) or animal biology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. (wikipedia.org)
  • life
  • Early in evolution, life forms developed the means to use chemicals to trap the energy needed to support life. (ceri.com)
  • model
  • It is the first model to show the evolution of complete germ-soma differentiation, where one part of the colony's cells (germ) eventually specializes in reproduction and the other part of the colony's cells (soma) specializes in survival. (eurekalert.org)
  • generally
  • Metal ion binding to such O-donors was required to build the biological polymers, since the bond is generally weak, it can catalyze the required reaction and dissociate after (i.e. (wikipedia.org)
