2016/6/15
In the recent philosophical literature, two questions have arisen concerning the status of natural selection: 1) Is it a population-level phenomenon, or is it an organism-level phenomenon? 2) Is it a ...
From Survivors to Replicators:Evolution by Natural Selection Revisited
Evolution by natural selection Replicator individual-based models Natural selection Diachronic
2016/6/12
For evolution by natural selection to occur it is classically admitted that the three ingredients ofcvariation, difference in fitness and heredity are necessary and sufficient. In this paper, I show u...
How to read “heritability” in the recipe approach to natural selection

2016/6/12
There are two ways evolution by natural selection (ENS) is conceptualized in the literature. One provides a ‘recipe’ for ENS incorporating three ingredients: variation, differences in fitness and heri...
Broken Mechanisms:Function,Pathology,and Natural Selection

2016/5/30
The following describes one distinct sense of ‘mechanism’ which is prevalent in biology and biomedicine and which has important epistemic benefits. According to this sense, mechanisms are defined by t...
The Paradox of Sexual Reproduction and the Levels of Selection:Can Sociobiology Shed a Light?
Evolutionary maintenance of sexual reproduction group selection inclusive fitness kin selection multilevel selection sociobiology
2016/5/30
The rejection of group selection in the 1960s left the evolutionary maintenance of sex bereft of its previous explanations and turned it into an anomaly or paradox. While the levels of selection debat...
Phrasing Techniques for Multi-Stroke Selection Gestures

2016/5/24
Pen gesture interfaces have difficulty supporting arbitrary
multiple-stroke selections because lifting the pen introduces
ambiguity as to whether the next stroke should add to the existing
selectio...
