- It’s sometimes said that the reason an animal does something is that it’s “for the good of the species.” Why is this argument incorrect?Discuss some advantages of sociality for animals. If social living has so many advantages, why do many animals successfully live alone?Imagine a friend tells you that humans are naturally aggressive, "just look at chimpanzees." Question: What specific information would you share with them about bonobos, muriquis, and the distance of our common ancestor with apes? At a minimum, you will need to reference the bonobo film, the article No Alpha Males Allowed, and the lecture.

- Consider the temperature effect in the sex determination of a turtle species represented in the graph below. 100 What effect would a decrease in temperature below the epivotal temperature have on sex ratios of these turtles? 50 FT MT Temperature Fewer males and females will result. None of the other answers is correct. No difference in the proportion of females to males will result as only colder temperatures will alter the sex ratio in the offspring. More males than females will result. More females than males will result. To Percent female O O O OOften relinquishing the young ones going to food shortage is one of the common behaviour as exhibit by mice. clarify how this conduct might have developed due to the life history and reproductive compromisesrences Belding's ground squirrels (Spermophilus beldingi) live in closely related groups. When they feed in the open, certain individuals (guard squirrels) watch for predators instead of feeding. The guard squirrels give an alarm call when a predator is sighted, allowing the rest of the group to run to safety. Researchers have noted that, because the alarm call draws attention to the guard, the guard is more likely to be caught by the predator and therefore has a lower survival rate in comparison with the other squirrels.Which of the following best explains the behavior of the guard squirrels? * anline la "eriods 1 and 2 iods MP1, Highschool hool MP3, MP4 The behavior of the guard squirrels increases the survival of cese relatives that share the genes of the guard squirrels. d Thu Fri Option Guard squirrels typically have recessive alleles, and by sacrificing themselves, they lessen the chance that recessive alleles will get passed on. The guard squirrels confuse the predator, lowering…
- What is migration and what triggers it? What forms of animal communication are there? ExplainAnimals have the innate ability to escape from predation, give its example.Fish produce a hormone called isotocin, a hormone that is similar to oxytocin in mammals. Both hormones, oxytocin and isotocin, have been linked to social behaviors including the suppression of social anxiety, trust, and attachment. Prior to this study, the relationship between isotocin in the bloodstream and the amount of aggression or submission individual cichlid fish display was unknown. The researchers hypothesized that isotocin would suppress aggressive behaviors in cichlids to promote social cohesion as these fish exist in large social groups (schools). To address this hypothesis, each of 10 fish were exposed to two treatments, 1 week apart. One at a time, a fish was randomly selected from the group of 10 and either injected with a saline solution (that served as the control) or with isotocin. After this injection, the fish was returned to its group and the amount of aggressive and submissive behaviors the fish demonstrated was recorded for the next 10 minutes. One week later…
