Transposable elements (TE), small mobile genetic elements unable to exist independently
of the host genome, were initially believed to be exclusively deleterious genomic parasites …

In experimental evolution, laboratory-controlled conditions select for the adaptation of
species, which can be monitored in real time. Despite the current popularity of such …

The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of
explanatory force unprecedented in our time--a landmark publication, both for its historical …

Microorganisms have been mutating and evolving on Earth for billions of years. Now, a field
of research has developed around the idea of using microorganisms to study evolution in …

The role of historical contingency in evolution has been much debated, but rarely tested.
Twelve initially identical populations of Escherichia coli were founded in 1988 to investigate …

Accumulating prokaryotic gene and genome sequences reveal that the exchange of genetic
information through both homology-dependent recombination and horizontal (lateral) gene …

The discovery of the molecular clock—a relatively constant rate of molecular evolution—
provided an insight into the mechanisms of molecular evolution, and created one of the most …

Experimental evolution systems allow the genomic study of adaptation, and so far this has
been done primarily in asexual systems with small genomes, such as bacteria and yeast …

Escherichia coli K-12 and B have been the subjects of classical experiments from which
much of our understanding of molecular genetics has emerged. We present here complete …

Evolution is an on-going process, and it can be studied experimentally in organisms with
rapid generations. My team has maintained 12 populations of Escherichia coli in a simple …
