Michod It is pretty much a standard topic for a first lecture, darwinian populations and transitions in individuality leading darwinian populations and transitions in individuality in to a standard reductionist sequence of biological topics that builds upon the studentsâ backgrounds in inorganic chemistry, climbing to everhigher levels of structural organization (culminating in the organism). Evolutionary transitions in individuality (hereafter, ETIs), such as the transition to multi-cellularity and the transition to social colonies, have been at the centre of evolutionary research, but only few attempts were made to systematically operationalize this concept. From this starting point, new analyses of the role of genes in evolution, darwinian populations and transitions in individuality the application of Darwinian ideas to cultural change, and "evolutionary transitions" that produce complex organisms and.

If differences in magnitude of evolutionary individuality are understood to arise at the level of populations, rather than at the level of individual reproducers, then membership in darwinian populations and transitions in individuality a Darwinian population, and hence status as a unit of selection, can be understood as a bivalent condition, even while members of darwinian populations and transitions in individuality some populations attain darwinian a higher degree of evolutionary individuality than members of other populations. In darwinian 1859 Darwin described a deceptively simple mechanism that he called natural selection, a combination of variation, inheritance, and reproductive success.

Understanding the response to selection is particularly challenging in the case of evolutionary transitions in individuality, because these transitions involve a shift in the very darwinian populations and transitions in individuality units of selection.
