Anthro2050 1st Edition Lecture 21Outline of Last Lecture I. Primate Cognition and CultureOutline of Current Lecture II. Primate Altruism and AffiliationIII.Primate ConservationCurrent LecturePrimate Altruism:Altruism: Getting along with and helping others at the cost of one's own fitness and without anyguaranteed help returned, although it often is.Why display altruistic behaviors when you can get put at risk?-group selection: having altruists in a group can help the group thrive. example, primates of various species all using various calls to alert each other to threats.- ken selection: since the goal of natural selection is to get as much of your genetic information into the next generation as possible, and since kin share genetic information with you, then helping them increases their fitness as well as your own. comes naturally, since in most groups primates are closely surrounded by kin.-reciprocal altruism is a system where you help others who help you in return. this requires knowing and keeping track of who has helped you, and coming in contact with that individual multiple times.- in humans, altruism goes further as the acts of altruism in humans are generally done with therecipient in mind, even if the person does not personally know the recipient (charities). Since primates do not do this generally, it is difficult to say if their acts of helping others is truly considered altruism.Primate Conservation-humans have been around for approximately 10,000 years. During that time, humans have expanded rapidly, and everywhere they expand, they modify the environments to fit their needs. However, since the human population has grown and expanded extremely quickly, environmental conservation is a very serious problem that needs to be handled with care.- it is a believed idea that the reason other homo species besides Homo sapiens are no longer around, is because Homo sapiens competed with them to extinction. We see modern primates These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.as well being pushed to their limits, by both natural and increasing human causes.- of the 625 currently known and existing primate species, 37 percent are endangered. In Madagascar alone, 60 percent of the species living there are endangered. Apes are heavily threatened, and it is believed in the next 10 years, Orangutans will exist only in captivity as they are dying out quickly in the wild.- habitat destruction is rapid and intense, especially with deforestation. Selective logging (the removal of only specific types of trees) has its pros and cons in the way it affects the primates in those areas. Fragmentation (breaking the forest into chunks of protected and destroyed area) has caused rapid changes to animals living in the protected areas of these chunks. Since they cannot leave safely into the opened spaces occupied by humans, they have a restricted pool of mates to breed with, which if the traits available are different enough from other groups in other fragments, over time can lead to speciation.- bushmeat is also a threat to local primates, as the people nearby need to feed themselves and their families, and will take what they can get, including for example, colobus monkeys.- the pet trade of people taking in primates as pets is also risky and dangerous, as people often do not fully know how to care for a primate, and forget that primates are not domesticated like cats and dogs are.- when eating primates or keeping them as pets, we run in to zoonoses. Zoonoses are infections and disease transmitted from animals to humans and each other. One example is ebola. Ebola isnot pleasant, but often not fatal to humans. However, it is very fatal to gorillas. During the 2005 ebola outbreak, gorillas were dying in huge numbers. In just one study group that year 5000 gorillas died from
