Uniquely explain the relationship between primate mating groups and sexual dimorphism in your own words.
Step by step
Solved in 2 steps
- Describe what sexual dimorphism is and why its existence is puzzling.My college Bio teacher asked me this question in response to one of my photos I posted on Facebook: "I wonder why some birds exhibit sexual dimorphism while others do not." Can someone explain this phenomenom in detail?Why does sexual dimorphism have important implications for studying human evolution? Explain why and prove it with examples.
- Why do females usually have the control in selecting mate and explain sexual dimorphism.What is sexual dimorphism? How can you say human beings exhibit sexual dimorphism?What causes sexual dimorphism? Give some examples of sexually dimorphic species, and why you think that form of sexual dimorphism arose.
- Polygyny is a common mating system in nature. Which one of the following scenarios is LEAST likely to result in a polygynous mating system? Male stalk-eyed flies form leks where receptive females come visit Male Neotropical giant damselfly defend water-filled tree holes, which are the oviposition sites for females. Suitable tree holes for oviposition are rare and females must mate with the resident male in exchange for access to the oviposition sites. Male Bengal tigers defend large territories that contain food sources. Female Bengal tigers visit male territories to mate. The density of the Bengal tiger is extremely low that male tigers rarely encounter more than one female in their lifetime. In the bumblebee-wolf Philanthus bicinctus, females are unreceptive until they finish constructing the long underground burrow as nest sites. Males search for locations containing a number of newly constructed burrows and attempt to control these sites against the intruders. Your cousin Peter…You have received a $500,000 grant from the National Science Foundation to study male signalling in peacock spiders. After your university takes most of that money for overhead costs, you now have a small amount left over to spend on peacock spider research over the next 3 years. What is the first question that you would focus on that you think would increase our understanding of peacock spider male displays the most? State a relevant hypothesis and explain briefly how you would go about testing it.Define sexual selection and describe an example of intersexual and intrasexual sexual selection in animals. Be sure to detail what trait(s) is/are being sexually selected.
- In seahorses, males incubate and care for offspring. Thus, the males are more likely to be tied up in reproduction at any point in time relative to females. Which sex do you predict will be the choosey sex in this species and why? Males -- because fewer are available to mate Males – because male-male competition is incredibly strong Females – because sperm are cheap to produce Female – because the operational sex ratio is biased in their favor The sperm of chimpanzees have faster swimming speeds than those of gorillas. Based on what you know about sperm competition, what would you predict about differences between these two species in female re-mating frequency and sperm viability? In chimps, females mate only once and sperm are viable for only a day In chimps, females mate multiply and sperm live for a long time In chimps, females mate only one, and sperm live for a long time In chimps, females mate multiply, and sperm live for only a day Which of the following sexual traits is…Male parental care occurs in only 7% of fishes and amphibianspecies with internal fertilization but in 69% of species with externalfertilization. Propose an explanation for why this is so.in sexual selection I need an explanation of why one sex is more choosy than the other
