Answer to Question 1
Answer: Reproductive fitness is a function of the success with which an organism reproduces. Reproduction is more costly to females in terms of the cost, time, and effort, and is far less costly for males. Because the costs of reproduction for females are high, they selectively seek out mates who appear likely to possess the necessary resources to invest in the rearing of offspring. Evolutionary researchers use this idea to explain why women are more interested than are men in such characteristics as ambition, industriousness, and good earning capacity. They also use this idea to explain why women are more concerned with emotional fidelity than with sexual fidelity. In contrast, because the cost of reproduction for males is low, they seek to reproduce with as many mates as possible. Of course, they do not seek out just any mate; they seek out mates who seem reproductively fit. Evolutionary researchers use this idea to explain why physical attractiveness seems more important to men and why men are more concerned with sexual fidelity than with emotional fidelity.
