Microbial experimental evolution
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2009Microbes have been widely used in experimental evolutionary studies because they possess a variety of valuable traits that facilitate large-scale experimentation. Many replicated populations can be cultured in the laboratory simultaneously along with appropriate controls.

Trends in Ecology & Evolution, 1999
The recent ability to select functional RNA molecules through combinatorial chemistry has ignited exobiological research by offering a set of tools for testing early theories of RNA evolution without the need for organisms. This process can retrieve molecules present in as few as one in 1 x 1015 sequences, which suggests that careful design may allow ...

Strengths and weaknesses of experimental evolution
Trends in Ecology & Evolution, 2012A recent article in TREE [1] presented a heavily documented review of experimental evolution, addressing three major issues: main questions and applications; experimental design and study systems; and caveats and limitations. Here, we comment on the latter issue.

Experimental Evolution of Poxviruses
Experimental evolution is the process of exposing virus populations to defined selective pressures in a laboratory setting to identify adaptive changes. Coupled with deep sequencing, this experimental approach allows for nucleotide-level resolution of poxvirus adaptive strategies over time.Shefali, Banerjee +2 more

Experimental evolution withDrosophila
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2009Experimental evolution is a powerful approach that can be used for the study of adaptation. Evolutionary biologists often use Drosophila as a model organism in experiments that test theories about the evolution of traits related to fitness. Such evolution experiments can take three forms: direct selection for a trait of interest; surveys of traits of ...

Abstract For evolutionary biologists, an unfortunate feature of the past century of genetics is that much of what we know comes from broken genes. The analysis of mutants shows us what evolution by natural selection overwhelmingly discards: dysfunctional genotypes.

Experimental Evolution in the Genomic Era
This article is dedicated to delineating experimental evolution, with a specific focus on its application in multicellular organisms. The strengths of experimental evolution as an efficient approach for deciphering the bases of evolutionary processes are emphasized, and the insights into different fields, e.g.Barghi, N. ; https://orcid.org/0000-0003-3700-0971 +2 more

Towards evolution of experimental robotics
1998This paper introduces Japanese research program for experimental robotics. Part one describes an ongoing inter-university research program on intelligent robotics. The three year research program, supported by a grant from the Japanese Ministry of Education, aims to study mechanisms for the emergence of robotic intelligence and autonomy.
