They are therefore commonly used for experimental evolution studies. The bacterial species most commonly used for experimental evolution include P. fluorescens, [35] Pseudomonas aeruginosa, [36] Enterococcus faecalis [37] and E. coli (see below), while the Yeast S. cerevisiae has been used as a model for the study of eukaryotic evolution.

The 12 E. coli LTEE populations on June 25, 2008. [1]The E. coli long-term evolution experiment (LTEE) is an ongoing study in experimental evolution begun by Richard Lenski at the University of California, Irvine, carried on by Lenski and colleagues at Michigan State University, [2] and currently overseen by Jeffrey Barrick at the University of Texas at Austin.

The basic mechanisms of evolution are applied directly or indirectly to come up with novel designs or solve problems that are difficult to solve otherwise. The research generated in these applied fields, contribute towards progress, especially from work on evolution in computer science and engineering fields such as mechanical engineering. [5]

A pre-programmed task, as in a military maneuver, using this definition, may be termed an "evolution." After the publication of Charles Darwin 's The Origin of Species in 1859, "evolution" became primarily associated with biological evolution as a non-guided process for the differentiation of forms of life from a common ancestor.
Given enough time, space, and money, any organism could be used for experimental evolution studies. However, those with rapid generation times , high mutation rates , large population sizes , and small sizes increase the feasibility of experimental studies in a laboratory context.
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [40] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
