Step by step
Solved in 2 steps
- What are Mate Preferences Between Women and Men? why do females have a greater disadvantage compared to males concerning sexual reproduction? How has this difference between the sex shape sexual selection in general? Choose one form of communication and explain how it is used by competing sex is attracting a mate. How can altruism be adaptive if it can result in fewer offspring for an individual?
- How might the following findings be understood in terms of the adaptive value of female mate preferences? Deep-voiced men have more children in a traditional hunter- gatherer culture, the Hazda of Tanzania. Taller men are more likely to be chosen in speed-dating competitions than their shorter rivals (Belot and Fancesconi 2006) and are more likely to be chosen as sperm donors by women in California (Egan 2006). Images of men with slightly bloodshot eyes are judged less attractive than photographs of the same men in which the whites of the eyes are clear (Provine et al. 2011). Please Do not write from an online sourceEarlier explanations of altruistic behavior as a form of group selec-tion have been supplanted by Hamilton’s hypothesis of kin selection. What distinguishes kin selection and how does it accord with the no-tion of inclusive fitness, the relative number of an individual’s alleles that pass to the next generation?Do animals benefit their own biological fitness if they sacrifice food or a chance to breed and thereby allow their kin to have more offspring? Is such behavior true altruism? Why or why not?
- What are indirect fitness benefits of siblicide? When would an individual gain more from siblicide than from inclusive fitness benefits? When might it be worth it for a subordinate to fight to the death with its dominant sibling?In a species of birds, males court females by dancing and subordinate males are seen to join a dominant male and help in his dancing displays, though the subordinate receives no mating opportunities. If the subordinate male DOES NOT inherit the dominant male's territory upon its death, how would you explain this cooperative behavior? O Altruism, because the subordinate is receiving direct benefits O Mutualism, because the subordinate is receiving direct benefits O Altruism, because the subordinate is receiving indirect benefits O Mutualism, because the subordinate is receiving indirect benefitsHamilton's Rule describes the relationship between cost and relationship in the evolution of altruistic behavior. Which of the following do not support Hamilton's rule: In colonies of Naked Mole Rates, only one female is reproductive. Cattle egrets sometimes kill their siblings. Wood mouse sperm will sacrifice themselves to assist a "sibling" sperm to fertilize an egg. O A Prairie Dog trills in response to an oncoming predator and is more likely to be eaten because it exhibits this behavior.
