Culture and Transitions in Individuality
Several biologists and philosophers have been arguing, for a while now, that a Darwinian evolutionary dynamics might take place not only in the distribution of phenotypic traits in a particular kind of population, but also in the very dimensions that are used to track those, bringing about new kinds of populations, given certain special circumstances. These "major" evolutionary transitions have...
متن کاملMajor transitions in human evolution.
Evolutionary problems are often considered in terms of 'origins', and research in human evolution seen as a search for human origins. However, evolution, including human evolution, is a process of transitions from one state to another, and so questions are best put in terms of understanding the nature of those transitions. This paper discusses how the contributions to the themed issue 'Major tr...
متن کاملEvolution of complexity in the volvocine algae: transitions in individuality through Darwin's eye.
The transition from unicellular to differentiated multicellular organisms constitutes an increase in the level complexity, because previously existing individuals are combined to form a new, higher-level individual. The volvocine algae represent a unique opportunity to study this transition because they diverged relatively recently from unicellular relatives and because extant species display a...
متن کاملTime and Fitness in Evolutionary Transitions in Individuality
It is striking that the concept of fitness although fundamental in evolutionary theory, still remains ambiguous. I argue here that time, although usually neglected, is an important parameter in regards to the concept of fitness. I will show some of the benefits of taking it seriously using the example of recent debates over evolutionary transitions in individuality. I start from Okasha’s assert...
متن کاملSocial niche construction and evolutionary transitions in individuality
Social evolution theory conventionally takes an externalist explanatory stance, treating observed cooperation as explanandum and the positive assortment of cooperative behaviour as explanans. We ask how the circumstances bringing about this positive assortment arose in the first place. Rather than merely push the explanatory problem back a step, we move from an externalist to an interactionist ...
