Summary Introduction
Introduction: Certainty of paternity is the degree to which a probable parent individual can be sure that an offspring is truly his or hers. In many species, males fertilize eggs externally to ensure their paternity and provide parental care to eggs or new offspring. In species with internal fertilization, male parent cannot be sure of parentage, but the females are 100% certain the offspring are theirs and provide parental care to their young ones.

In Biology of Beauty, Cowley found that contemporaryfemales are attracted to males with broad foreheads and strong chins, and that this effect persisted across different cultures. How did Cowley explain this result?
A. This is a trick question- this attraction is culturally relative
B. Males compete for access to females by developing these features as a form of male-male competition
C. There is no evidence that females really are differentially attracted to males with these features
D. Attraction to males with these features is adaptive for females because males with these traits are usually sexually mature and have healthy immune systems
E. Only some human cultures value these traits as attractive.

Both a. and b.
d.

She will become less attached to them and start to neglect them
c.
She will become frightened of them and try to flee

- Conventional signals are not costly because they often entail slight visible variations in only a small portion of the body, but they can be rendered honest through social reinforcement. Which example best demonstrates this case? A. Birds with large throat patches with poor fighting ability are attacked more often by dominant birds. B. Aggressive wasps with facial patterns indicating their fighting ability are less likely to be attacked. C. A dominant lion is able to evict younger chalengers from the pride. D.

When males meet a female and self-sacrifice, it activates enzymes that make his sperm more fit and able to fertilize more eggs. b. Males are able to mate with one female, then mate with another female nearby, before being devoured by the first female. C. Males only use self-sacrificing behaviour once they have mated with several females and have exhausted their sperm supplies. d. The chance of a male meeting more than one female is quite low; self-sacrifice maximizes mating time with and sperm transfer to any female the male finds.arrow_forwardYou discover a new species of reptile that can either lay eggs or have live birth.
