Document Summary
The similarities in personality between siblings is less than the similarities in look, sound and movement. Prof"s example from 8th grade: 50 kids, 25 boys and 25 girls, favourite girl: darlene, favourite boy: jimmy, prof ended up getting 3: strongest, most athletic and smartest, prof"s (cid:374)e(cid:448)er-never occupation: playboy. Images and reality: the essence of competition is not direct confrontation. It consists instead of behaviours designed to acquire limited or better resources at the expense of others who are attempting to acquire those resources. Competitors need not ever meet to engage in intrasexual competition. Poor mating choices typically are costlier to females than to males in the currency of reproductive success: females look for males who will invest and stay together with them and their offspring. What women must offer: the primary reproductive constraint for men consists of gaining access to reproductively valuable women. Study 1: constructing a taxonomy of acts and tactics used in intrasexual competition.
