Natural and sexual selection in a monogamous historical human population.
Whether and how human populations exposed to the agricultural revolution are still affected by Darwinian selection remains controversial among social scientists, biologists, and the general public. Although methods of studying selection in natural populations are well established, our understanding of selection in humans has been limited by the availability of suitable datasets. Here, we presen...
متن کاملMulti-level selection in biology
Okasha (2006) proposed distinguishing aspects of selection: those based in particle level traits (MSL1), and those based in group level traits (MSL2). It is proposed here that MSL1 can usefully be further split into two aspects, one (MLS1 E) representing selection of particles based in their individual interaction with environmental properties, and one (MLS1 G) representing Multi Level Selectio...
متن کاملSexual Selection: Copycat Mating
Female zebra finches may be influenced by the choices of other females when selecting mates, challenging the view that mate-choice copying should not occur in species with biparental care. Choosing a mate is not a simple business. A female needs a male in order to reproduce, but how does she know which one to pick? How can she find a good mate without wasting too much time and effort? One answe...
متن کاملAn Individual-based Approach To Multi-level Selection
Evolutionary Algorithms (EAs) are in this case counter-intuitive since they try to evolve a solution for the entire problem as a whole. EAs may show improvement when they can create more complex evolutionary units through some form of cooperative combination of sub-solutions similar to divide-and-conquer. In other words, instead of trying to evolve a single solution for the problem, solutions m...
متن کاملSexual selection and mating systems.
Sexual selection is among the most powerful of all evolutionary forces. It occurs when individuals within one sex secure mates and produce offspring at the expense of other individuals within the same sex. Darwin was first to recognize the power of sexual selection to change male and female phenotypes, and, in noting that sexual selection is nonubiquitous, Darwin was also first to recognize the...
