ALCOHOL AND PRIMITIVE RACES.

Arms Races and Car Races

Evolutionary car racing (ECR) is extended to the case of two cars racing on the same track. A sensor representation is devised, and various methods of evolving car controllers for competitive racing are explored. ECR can be combined with co-evolution in a wide variety of ways, and one aspect which is explored here is the relative-absolute fitness continuum. Systematical behavioural differences ...

Molecular analysis and validation of primitive races peach palm (Bactris gasipaes) by means of markers RAPD

Molecular markers were used to examine the genetic variability of eight landraces of peach palm (Bactris gasipaes var. gasipaes) and two wild populations (Bactris gasipaes var. chichagui), their relationships and genetic structures. Two hundred plants of these 8 races were used and 18 plants of the two wild populations, one from the Magdalena River, Colômbia, and the other from the Xingu River,...

Human races

Carl was not a geneticist by training or at heart, and although cognizant of horizontal gene transfer, saw it as a creative force at the beginning of cellular evolution (the ‘progenote’ stage), not as a challenge to defining the ‘true’ relationships between living things now. Most of the phylogenetic community still holds Carl’s belief as foundational. Nor was he, as Mayr complained, a card-car...

Arms Races and Negotiations

Two players simultaneously decide whether or not to acquire new weapons in an arms race game. Each player’s type determines his propensity to arm. Types are private information, and are independently drawn from a continuous distribution. With probability close to one, the best outcome for each player is for neither to acquire new weapons (although each prefers to acquire new weapons if he think...
