Robustness of self-organised systems to changes in individual level behaviour: an example from real and simulated self-organised snail aggregations
Perfect behaviours that are optimal to the environment an agent operates within rarely exist in real animals or in robotic systems. The costs (be they biological or economic) of building sensors an…

Natural Selection In Utero Contributes to the Male Longevity Deficit in Contemporary Human Populations
Much literature invokes natural selection to explain the pervasive deficit in the average lifespan of men compared to women.1 The explanation assumes that mothers, not fathers, provisioned childr…

Design of a dynamic model of genes with multiple autonomous regulatory modules by evolution in silico
A new approach to design a dynamic model of genes with multiple autonomous regulatory modules by evolution in silico is proposed. The approach is based on Genetic Algorithms, with new crossover ope…

On biological homochirality
Generalizing Landau’s spontaneous symmetry breaking arguments using the standard groupoid approach to stereochemistry allows reconsideration of the origin of biological homochirality. On Earth, lim…

Earth History and the Evolution of Caribbean Bats
Although the natural history of the Caribbean is better understood now than ever before, a general biogeographic explanation for the peculiar faunal composition of the islands remains elusive. New …

Roman roads: The hierarchical endosymbiosis of cognitive modules
Serial endosymbiosis theory provides a unifying paradigm for examining the interaction of cognitive modules at vastly different scales of biological, social, and cultural organization. A trivial bu…

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains
The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology an…

The Origin and Evolution of Viruses as Molecular Organisms
Viruses are the most abundant life forms and the repertoire of viral genes is greater than that of cellular genes. It is also evident that viruses have played a major role in driving cellular evolu…
