For this discussion post, I want you to search primates and tooluse: How did tool use begin? do all primates use tools? Why is thisso important for non-human primates? In your post-I want you totell us about the tool use you found and the primates who use it.Then, I want you to hyperlink the article, so we can see it. Andthen…do you think this tool use is similar to our humanancestors?
To summarize: 1. Look up primates and tool use; 2. Find anarticle you like, and want to share; 3. Summarize the article forus, and give us the article / webpage your found in a hyperlink; 4.Do you think this skill set is similar to those developed by our”not quite human yet” ancestors? Why or why not?
Answer:
•Order Primates of class Mammalia includes lemurs, tarsiers,monkeys, apes, and humans. Non-human primates live primarily in thetropical or subtropical regions of South America, Africa, andAsia.
•Characteristics:- possess adaptationsfor climbing trees, as they all descended from tree-dwellers.
•1) a rotating shoulderjoint,
• 2) a big toe that is widelyseparated from the other toes and thumbs, which are widelyseparated from fingers (except humans), which allow for grippingbranches,
•3) stereoscopicvision, twooverlapping fields of vision from the eyes, which allows for theperception of depth and gauging distance.
•4)Othercharacteristics of primates are brainsthat are larger than those of most other mammals,
•5)claws that have been modified into flattenednails,
•6) only oneoffspring per pregnancy, and a trend toward holding the bodyupright.
•Order Primates is divided into twogroups:
1. Prosimians include the bush babies of Africa, the lemurs ofMadagascar, and the lorises, pottos, andtarsiers of Southeast Asia.
2.Anthropoids include monkeys, apes, and humans.
[Note:- prosimianstend to be nocturnal (in contrast todiurnal anthropoids) and exhibit a smaller size and smaller brainthan anthropoids.]
•primates and tool use:-Primates arewell known for using tools for hunting or gathering food and water, cover forrain, and self-defence.
•chimpanzees have been using stone tools in the rainforests of Ivory Coast for at least4300 years. The chimpanzee Stone Age began at least that early, andmaybe even earlier.[says Boesch.] Chimpanzees don’t use fire, therefore they don’t need to know how todoit. To learn how tomakefire, they would needto already use it and value fire making skill.Lead researcher JuanLapuente, fromthe Comoe Chimpanzee Conservation Project, in IvoryCoast, explained thatusing similar brush-tipped sticks to dip into bees’ nests for honeywas common in chimpanzee populations acrossAfrica. “These chimps use especially long brush tips thatthey make specifically for water – much longer than those used forhoney. They are even capable of making spears to hunt otherprimates for meat, and are known to have developed specialized toolkits for foraging army ants.
•Wild capuchin monkeys useanvils and stone poundingtools.•These were use large,heavy stones to crack hard Panda nuts as well as small stones to break open softerpalm oil nuts.
•Orangutans inthe wild have developed and passed along a way to makeimprovised whistlesfrom bundles of leaves, which they useto help ward off predators. This apparently marks the first time ananimal has been known to use a tool to help itcommunicate,.Orangutans repel insects by waving a bough.
- Bonobos may break off parts of trees and drag themnoisily in the direction they want others tofollow.
•Baboons, members of the old world monkeysubfamily, use twigs as tools to pry insects or pebbles from theground. Bonobos may break off parts of trees and drag themnoisily in the direction they want others to follow.
•Gorillas are knownto use branches as walkingsticks to test water depth andtrunks from shrubs as makeshift bridges to cross deep patches ofswamp. While other great apes mostly use tools to help get at food,gorillas apparently use them to help them deal with theirsurroundings in other ways. gorillas usesticks to rake in items; in captivity, they copy humans’ actionssuch as tickling others with twigs.
•Dolphins are renowned as brainiacs ofthe seas, and scientists recently discovered they can be tool-usingworkaholics as well. A group of bottlenose dolphins in Shark Bay,Australia, carries marine sponges in their beaks to stirocean-bottom sand and uncover prey, spending more time hunting withtools than any animal besides humans.
•Sea otters, the largest members of the weasel family,use stones to hammer abalone shells off the rocks and crack thehard shells of prey open, making them the only known tool-usingmarine mammal for decades, until dolphins camealong.
•Elephants are among themost intelligent animals in the world, with brains larger than those of any other landanimal. Anecdotes suggest they can intentionally drop logs or rockson electric fences to short them out and plug up water holes withballs of chewed bark to keep other animals from drinking them away.Asian elephants are even known to systematically modify branches toswat at flies, breaking them down to ideal lengths for attackingthe insects.
Gibbons incaptivity have hung pieces of rope or blanket on their cages tomake swings.
•Early humans in East Africa used hammerstones to strike stonecores and produce sharp flakes. For more than 2 million years,early humans used these tools to cut, pound, crush, and access newfoods—including meat from large animals. Thestone toolsmay have been made by Australopithecus afarensis orKenyanthropus platyops— (a3.2 to 3.5-million-year-old Pliocene hominin fossil discovered in1999) the species whose best fossil example is Lucy, whichinhabited East Africa at the same time as the date of theoldest stonetools.
