>>11403122sure, it just depends what you mean by group selection. Group selection can be more precisely described by looking at competition at the individual level. Any case of group selection can be described like this, and cases of seemingly irrational group choices can be explained by individual competition. Competition between individuals doesn't always make sense either. It can be more precisely described by genetic competition, where success of the gene is more important than success of the individual.
While groups can outcompete other groups of the same kind, individuals can outcompete other individuals of the same kind, a gene doesn't compete with other copies of itself, as it's the unit that evolution actually occurs at. At the evolutionary scale, all that matters is success of the gene, which is why organisms that are seemingly unsuccessful in groups, or even unsuccessful as individuals persist, or even flourish.
