Introduction: Epigenetics involves the study of heritable changes in the regulation of gene activity and expression that are not dependent on gene sequence. Main mechanisms of epigenetic modifications are DNA methylation, Histone modification and Nucleosome positioning. Several studies have shown that these modifications are related to cancer initiation, progression or tumor metastasis. In cont...

Though most documented sign languages make use of space to denote relationships between predicate arguments, studies of emerging sign languages suggest that spatial reference does not emerge fully-formed but takes time to develop. We present an artificial sign language learning experiment that expands the cultural evolutionary framework to investigate complex linguistic constructions. Our resul...

Aptamers are the artificial single-stranded DNA or RNA sequences (more recently, peptides) that fold into secondary and tertiary structures making them bind to certain targets with extremely high specificity. Aptamers were reported for the first time in 1990, a number of their unique features make them a more effective choice than antibodies. Aptamers typically generated through Systematic Ev...

When humans and other animals make cultural innovations, they also change their environment, thereby imposing new selective pressures that can modify their biological traits. For example, there is evidence that dairy farming by humans favored alleles for adult lactose tolerance. Similarly, the invention of cooking possibly affected the evolution of jaw and tooth morphology. However, when it com...

In this paper a computational model of the cultural evolution process is described. This model integrates several traditional approaches to modeling cultural evolution into a common conceptual framework. This framework depicts cultural evolution as a process of dual inheritance. At the micro-evolutionary level there is a population of individuals, each described in terms of a set of behavioral ...

This poster abstract outlines initial results from a multi-disciplinary research project called ‘the emergence of artificial culture in robot societies’ whose overall aim is to investigate the processes and mechanisms by which protocultural behaviours, better described as traditions, might emerge in a free running collective robot system. We accept, as a working hypothesis, the idea that mimesi...
