Phylogenomics and computational biology play important roles in evolutionary informatics, changing the way we view the Tree of Life.

Evolutionary informatics is a sub-branch of informatics that addresses the algorithmic and technological tools (like information and analytical systems) needed to better manage data from research in ecology and evolutionary biology and answer evolutionary questions.[1]

As in bioinformatics and genomics, scientists studying biological evolution have gathered an increasingly large volume of information, resulting in information management problems. Additionally, as bioinformatics and genomics are pertinent to the study of evolution, utilization of information from those areas is of concern in evolutionary informatics.

History

Evolutionary informatics has evolved out of a wide variety of scientific, mathematical, and computational endeavors, including evolutionary biology, evolutionary computation, algorithmic and evolutionary algorithmic research, and software development.[1]

In 2006, the National Science Foundation-sponsored National Evolutionary Synthesis Center (NESCent) promoted the NESCent Evolutionary Informatics Working Group to "develop community cohesion on issues of standards and interoperability" of the infrastructure and tools used for "integrating evolutionary methodology into biological data analysis."[2] In subsequent years, NESCent became involved in creating the Hackathons, Interoperability, Phylogenies (HIP) working group and advancing several databases, libraries, and ontologies in the field of evolutionary biology.[3][4]

In 2007, Professor Robert Marks included the term "evolutionary informatics" in the title and content of his Baylor University-hosted website Evolutionary Informatics Laboratory (EIL). The university's administration subsequently took down the website for having "unapproved research," which reportedly included unpublished scholarly papers coauthored by Marks and intelligent design advocate William A. Dembski.[5] Marks moved the content removed from Baylor servers to a new domain. Its front page stated the following concerning evolutionary informatics:

Evolutionary informatics merges theories of evolution and information, thereby wedding the natural, engineering, and mathematical sciences. Evolutionary informatics studies how evolving systems incorporate, transform, and export information. The Evolutionary Informatics Laboratory explores the conceptual foundations, mathematical development, and empirical application of evolutionary informatics. The principal theme of the lab’s research is teasing apart the respective roles of internally generated and externally applied information in the performance of evolutionary systems.[6]

In June 2010, the first ever Informatics for Phylogenetics, Evolution, and Biodiversity (iEvoBio) Conference took place in Portland, Oregon, with the goal of "both to catalyse the development of new tools, and to increase awareness of the possibilities offered by existing technologies."[7] As of 2020, the conference still occurs.

Application

Evolutionary informatics can help tackle problems and tasks such as the following[1]:

  • Connecting genomics data with scalable taxonomic concepts and data to reduce "the growing number of lineages that lack formal taxonomic names"
  • Leveraging legacy biodiversity data by digitizing it, semantically enhancing it, and making it more portable
  • Building "sustainable digital community repositories that provide access to rich data and metadata" in the field of evolutionary biology
  • Building "a semantic web for evolutionary biology" that uses data querying, mining, and integration tools
  • Developing algorithms to better model evolutionary changes

Informatics

The U.S. National Science Foundation-funded NESCent has been one of the key groups responsible for advancing the application of informatics to evolutionary biology problems in the twenty-first century. Started in 2004, NESCent has furthered several informatics goals in the field of evolutionary informatics by[4]:

  • contributing to the Generic Model Organism Database (GMOD) project "to further develop the data model for evolutionary datatypes (named organisms, georeferenced collections, genetic and phenotypic variability, and phylogenies), to develop web applications for accessing these types of data, and to provide user support for adoption of the GMOD platform for evolutionary model organisms."
  • promoting and contributing to several projects (Phenoscape, Phenex, OBO Foundry) that work with phenotype ontologies and their application to evolutionary morphologies.
  • promoting the integration of geoinformatics with evolutionary informatics so researcher may better "integrate population genetic and phylogenetic models of multiple taxa with data describing present and past environments and climate"; one such success has been GeoPhyloBuilder.
  • integrating the wide variety of existing tools to interoperate with each other through hack-a-thons and cooperation with open-source developers.
  • "working to establish a digital repository for published data" in the biosciences.

Application of algorithms to evolutionary biology

The notion that information processing is essential to the evolutionary process predates the entry of the term "informatics" into the English language around 1967.[8] Investigators were arguing as early as the 1940s that certain principles of information processing apply to both living and engineered systems, with much of their thinking encapsulated in Norbert Wiener's Cybernetics: or Control and Communication in the Animal and the Machine.[9] Wiener regarded evolution as "phylogenetic learning," or accrual of information in the genome.[9]

Modern work has focused on evolution as more of an optimization of fitness functions, addressing the role of information in optimization. Work by researchers David Wolpert and William G. Macready in the mid-1990s established that evolutionary algorithms have average performance no better than that of random search. They argued that superior performance could be achieved only if algorithms incorporate prior knowledge of problems, and provided an information-geometric analysis of how algorithms and problems are matched (and mismatched).[10][11]

After reviewing Wolper and Macready's work on the "no free lunch" theorems, researcher Thomas M. English argued there was no free lunch due to an underlying "conservation of information," and that the duo's work "mistakes selection bias for prior information of the objective function."[12] In 2000, English turned to Kolmogorov complexity as a measure of information in instances of fitness functions and optimization algorithms. He observed that almost all problems exhibit a high degree of Kolmogorov randomness, and thus those problems are easy for almost all optimization algorithms.[13] English later gave a new perspective on conservation by way of characterizing approximate satisfaction of a necessary and sufficient condition for "no free lunch."[14]

Wolpert and Macready went on to prove the existence of coevolutionary "free lunches" in 2005.[15] This may be interpreted as the discovery of a problem class for which some coevolutionary algorithms in biology are generally better informed than others of how to solve problems.
