Daily Transfers, Archiving Populations, and Measuring Fitness in the Long-Term Evolution Experiment with <em>Escherichia coli</em> Open
The Long-Term Evolution Experiment (LTEE) has followed twelve populations of Escherichia coli as they have adapted to a simple laboratory environment for more than 35 years and 77,000 bacterial generations. The setup and procedures used in…

Fluctuating environments select for short-term phenotypic variation leading to long-term exploration Open
Genetic spaces are often described in terms of fitness landscapes or genotype-to-phenotype maps, where each genetic sequence is associated with phenotypic properties and linked to other genotypes that are a single mutational step away. The…

The MODES Toolbox: Measurements of Open-Ended Dynamics in Evolving Systems Open
Building more open-ended evolutionary systems can simultaneously advance our understanding of biology, artificial life, and evolutionary computation. In order to do so, however, we need a way to determine when we are moving closer to this …

The Boundedness Illusion: Asymptotic projections from early evolution underestimate evolutionary potential Open
Open-ended evolution researchers seek to create systems that continually produce new evolutionary outcomes, attempting to reflect the power and diversity of evolution in nature. The specific metrics used (novelty, complexity, diversity, et…

Threshold for cooperation on irregular spatial networks Open
Cooperation is a defining attribute of life as we know it, from the delicate interactions of intracellular components to social behavior in groups. However, defection and exploitation are at least as ubiquitous. Evolutionary game theory is…

Gene duplications drive the evolution of complex traits and regulation Open
Gene duplications have been shown to promote evolvability in biology and in computational systems. We use digital evolution to explore why; that is, what characteristics of gene duplications increase evolutionary potential? Are duplication…
