chimpanzees and their use of tools. However, his argument that animals learn based on experience or observation is slightly more persuasive than his argument that animals are ruled by custom or instinct. One argument of Hume’s is that animals learn things based on experiences of cause and effect. He expands on this by giving an example of a horse not attempting to jump higher than it knows it can from past experience (Hume, pg. 68). This account of the reason of animals is persuasive because it can be seen as true…

Crack! The shell of an abalone breaks upon a rock after a sea otter repeatedly bangs the shell against the rock in order to retrieve the meat inside of it. Conducting an observation that validates sea otters’ use of tools would have to include the time and duration of the observation, the number of specimens to be observed, and a method of observation. The time and duration of the observation of the animal is a crucial element in the experiment. In “The Great Crow Fallacy,” the author states,…

the roots of collective learning from the use of stone tools to the present and its potential in the future. When I look at the technology around me, my phone, my laptop, my car, I think about the effort and knowledge that went into creating these things. The same kind of effort and knowledge went into creating human societies, religions, legal systems, literature, and sciences. All of this is not the work of one man but the collective effort of millions of minds interacting…

From the beginning of humankind tools people have used for the use of survival and livelihood. One of the most useful but underrated tools ever invented, the tomahawk’s humble beginnings go back thousands of years to the days of wood and stone. Of all of the forms that this tool took, pipe tomahawks have received the least attention. The pipe tomahawk and the DeQuindre tomahawk both possess great and interesting traits. Though a form of the hatchet, the tomahawk has a slightly more elaborate…

In discovering the capabilities of bonobos and chimpanzees making use of sophisticated pre-agricultural tools this potentially changes the way hominin evolution developed. Such usage of tools was once regarded as a particular characteristic of archaic pre-humans. Bonobos were observed performing complex action such as using tools to extract food, or using spears for attack or defense. Bonobos are similar to chimpanzees, but previously bonobos did not show a cultural diversity in use of tools as…

Background: The goal of this examination was to compare the suspect’s tools that were submitted to the markings that were found on seven (7) items of evidence. In order to determine if a tool that was submitted could have left a particular mark, class characteristics from both the tools and the mark were observed and recorded, as well as compared to one another in order to narrow down the list of potential tools that could have left a tool mark found on a given item of evidence. Some class…

In northeast Brazil, the capuchins have a food source limited to hard shelled fruits and seeds. As a survival adaptation they learned how to make use of the available sources by the use of stone tools. Interestingly enough, they don’t just use any old rock that they can find. The capuchins make sure that their “hammers” are the perfect size to swing with but are also made out of a hard enough material- such as quartzite. Sandstone is usually used as an anvil. The perfect tools don’t just go to…

1.1 Explain the typical axis conventions of the following machine tool in the form of a written report. Lathe Machine Tool Lathe machine is a machine tool that rotates the work piece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the work piece to create an object with symmetry about an axis of rotation. (n.d.) Typical axis conventions of the Lathe Machine tool • The work piece is…
