Time 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 ...
متن کاملCooperation and conflict during evolutionary transitions in individuality.
Cooperation received much less attention 30 years ago than other forms of ecological interaction, such as competition and predation. Workers generally viewed cooperation as being of limited interest, of special relevance to certain species (e.g. social insects, birds, humans and our primate relatives) but not of general significance to life on earth. This view has changed, due in large part to ...
متن کاملOn the reorganization of fitness during evolutionary transitions in individuality.
The basic problem in an evolutionary transition is to understand how a group of individuals becomes a new kind of individual, possessing the property of heritable variation in fitness at the new level of organization. During an evolutionary transition, for example, from single cells to multicellular organisms, the new higher-level evolutionary unit (multicellular organism) gains its emergent pr...
متن کاملA Multi-level Selection Theory of Evolutionary Transitions in Individuality
The organization of the living world is hierarchical—lower level units group together and cooperate to form higher level units of organization (genes, chromosomes, bacterialike cells, eukaryotic-like cells (cells in cells), multicellular organisms and societies). How this came about is far from clear. What is clear is that the major landmarks in the diversification of life have involved transit...
