Hello fresh is America's number one meal kit. Monday dot com work o s is a customisable platform that gives teams the ability to easily create the works oft where they need and want for their organization. What is the best way to conceptualize levels of selection in biology? And how do you divide up reality? The guest from our day, arvid agren, worked as a biologist on this problem.

One of the brilliant achievements of Darwin’s theory of natural selection was to help explain apparently “purposeful” or “designed” aspects of biology in a purely mechanistic theory of unguided evolution. Features are good if they help organisms survive. But should we put organisms at the center of our attention, or the genetic information that governs those features? Arvid Ågren helps us understand the attraction of the “selfish gene” view of evolution, as well as its shortcomings. This biological excursion has deep connections to philosophical issues of levels and emergence.
