Peacock Butterfly Predator Defenses The photographs below represent the experimental and control groups used in the peacock butterfly experiment discussed in Section 1.6. See if you can identify the experimental groups and match them up with the relevant control group(s). Hint: Identify which variable is being tested in each group (each variable has a control). A Wing spots painted out B Wing spots visible; wings silenced C Wing spots painted out; wings silenced D Wings painted but spots visible E Wings cut but not silenced F Wings painted, spots visible; wings cut, not silenced Peacock butterfly experiment A With wings folded, a peacock butterfly resembles a dead leaf, so it is appropriately camouflaged from predatory birds. B When a predatory bird approaches, a butterfly flicks its wings open and closed, revealing brilliant spots and producing hissing and clicking sounds. C Researchers tested whether the wing-flicking and sound-making behaviors of peacock butterflies affected predation by blue tits (a type of songbird). Experimental Treatment Number of Butterflies Eaten Wing spots concealed 5 of 10 (50%) Wings silenced 0 of 8 (0%) Wing spots painted out and wings silenced 8 of 10 (80%) No treatment 0 of 9 (0%) Proceedings of the Royal Society of London, Series B (2005) 272: 12031207. D The researchers painted out the spots of some butterflies, cut the soundmaking part of the wings on others, and did both to a third group; then exposed each butterfly to a hungry blue tit for 30 minutes. Results support only the hypothesis that peacock butterfly spots deter predatory birds. FIGURE 1.12 Testing the defensive value of two peacock butterfly behaviors.

Sexual selection is kind of natural selection in which characteristics related to mating success are the targets of selection. male features are always the key characteristics selected. competition among individuals of the same sex is always involved. infertility is the most common problem. All of the choices are correct.
Which of the following sexual traits is LEAST likely to have evolved due to male-male competition for mates, also known as intraspecific sexual selection?a) Enlarged femurs that an insect uses to kick other malesb) Brushes on the tip of a dragonfly penis used to remove sperm of other malesc) Mate-guarding behavior of a warbler during the female’s fertile periodd) Elongated tails of the male swordtail fish used during courtship
During mating season, male rams compete with each other for access to females. This describes (please just select one answer the one the best fits) intersexual selection intrasexual selection the direct benefits model Hamilton-Zuk hypothesis Fisherian sexual selection
Intrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.
Some physical traits are a disadvantage for species survival, explain the role sexual selection plays in maintaining these traits in the population.
