Document Summary
What is the adaptive value concerns the reproductive advantage of the behaviour. So be cautious of this when answer all the mc q on the exam. Does it represent sexual competition among females: there must be differences between available males, males must be in short supply, males limit their mating effort for parental effort. Females compete indirectly through: visual cues, bringing down of other females. Adaptive value of indirect competition: due to high parental investment: don"t want to risk any potential offspring, so instead compete through these indirect methods to acquire high quality males and resources for their offspring. When males are in short supply or if there are large diffs in males: females start competing for those higher quality males (= high paternal investment) Males: choose youth & health, but not necessarily peak fertility. Bateman"s principle (**exam know reproductive investments are related to bateman"s principle)) Females: greater parental investment, maximum reproductive potential < males, greater selectivity in mates.
