Exaptation and emergence as mechanisms to cross fitness valleys during evolution: an example using simulated homing behaviour

Evolution is often considered a gradual hill climbing process, slowly increasing the fitness of organisms. I investigate the evolution of homing behaviour in simulated intertidal limpets. In order to evolve path integration as a homing mechanism, a temporary reduction in an organism’s fitness is required – since high developmental costs occur before a successful homing strategy evolves. Simple hill-climbing algorithms, therefore, only rarely result in the evolution of a functional homing behaviour. The inclusion of a second behaviour (trail-following) greatly increases the frequency of success of evolution of a path integration strategy. Initially an emergent homing behaviour is formed combining path integration with trail following. This also demonstrates evolution through exaptation, since the original role of trail following is likely to be unrelated to homing. Analysis of the fitness landscapes of homing in the presence of trail-following behaviour shows a high variability of fitness, which results in the formation of ‘stepping-stones’ of high fitness across fitness valleys. By using these stepping-stones, simple hill-climbing algorithms can reach the global maximum fitness value

Dynamic 3D Network Data Visualization

Monitoring network traffic has always been an arduous and tedious task because of the complexity and sheer volume of network data that is being consistently generated. In addition, network growth and new technologies are rapidly increasing these levels of complexity and volume. An effective technique in understanding and managing a large dataset, such as network traffic, is data visualization. There are several tools that attempt to turn network traffic into visual stimuli. Many of these do so in 2D space and those that are 3D lack the ability to display network patterns effectively. Existing 3D network visualization tools lack user interaction, dynamic generation, and intuitiveness. This project proposes a user-friendly 3D network visualization application that creates both dynamic and interactive visuals. This application was built using the Bablyon.js graphics framework and uses anonymized data collected from a campus network

Non-pareille? Issues in Modern French Photo-Essayism

[FIRST PARAGRAPH][L]’esthéthique sait depuis longtemps que l’image, contrairement à ce que croit et fait croire la machine d’information, montre toujours moins bien que les mots toute grandeur qui passe la mesure: horreur, gloire, sublimité, extase. (Comolli and Rancière 1997, 66) It may seem odd, in a general analysis of the modern French essay accompanying photography, that there is no reproduction of photographs. This is however a deliberate choice, and not one without precedent, as the collection of Michel Butor’s photo-essays into one photo-less volume shows. For it would seem in this age of the image – dubbed by essayists as diverse as Debray (1992), Flusser (2000 [1983]), Gervereau (2000), Glissant (1994) as the televisual era – the written word has tended to be downplayed. This is no more the case than in the photo-essay, a sub-genre largely overlooked and under-theorised, generally subsumed within photo-journalism, and in which photographic sequences are preferred to written text (see Mélon, in Baetens and Gonzalez 1996, 138–55)
