Summary

This article is research about Brains, Tools, Innovation, and Biogeography in Crows and Ravens by Knud Jonsson, Pierre-Henri Fabre1 and Martin Irestedt. In their research they studied the relationships of different species of Crows and Ravens in different countries. Also, they measured brain sizes, body mass, tools that they used and strategies of feeding. As the result of their research they have found out that that crows originated in the Palaearctic in the Miocene from where they spread from North America then Caribbean, Africa, Australia and Asia. Thus, there is no explanation to the brain sizes of Crows and Ravens has any relation on tool use, strategies of getting food and colonization. Rather it appears that the large brain had already evolved from their ancestor of Crows and Ravens, causing a high cognitive and ability to overcome challenges using their innovative talent. According to Knud Jonsson “Having large brain doesn’t mean their smart but what matter is the knowledge in it”.

    The aim of this essay is to investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group is a group of social theories, postulating that primate cognition is a result of complex social interactions between individuals, and in this essay this group will be represented by the Social Brain Hypothesis proposed by British anthropologist Robin Dunbar. The second group encompasses the ecological theories that are based on a premise that primate intelligence originated from complex interactions with the environment. A “delegate” from this group in my discussion will be the Visual Specialisation Hypothesis introduced by Robert Barton (1998), who argues that primate encephalisation is connected to frugivorous diet and the need of advanced visual abilities. Finally, the Cultural Intelligence Hypothesis, which is a general name to multiple related views, proposes that large-brained primates possess “general intelligence” due to their great behavioural flexibility. This final theory will be included in the comparison just to offer an alternative view to the two mainly discussed theories above.…

    Krautwurst uses words such as “smart”, “perceptive”, and “exceedingly resourceful” to highlight the birds’ unique abilities. In other words, the birds are clever and proficient problem solvers.

    Early on in the novel, Chauntecleer is portrayed as a short tempered, vain, and arrogant ruler who is not at all likeable. While he is proud and undoubtedly stubborn, he is also characterized as fair, compassionate, and just. With his noble bearing, Chauntecleer keeps a sense of order in his land and the animals' lives by crowing the canonical hours and occasional crows in his strong magnificent voice. His crows are compared to the clock of the community. "Seven times a day, dutifully, with a deep sense of their importance, and by the immemorial command of the Divine, Chauntecleer crowed his canonical crows" (page 12). Crowing is his job and when he leads by his crows, the hens in his coop and the animals in his land are happy and unafraid, he is even able to make wrong things right.…

    Often times, when an individual with only basic knowledge of biological anthropology considers the adaptation and evolution a group, the importance of coevolution is either overlooked or understated. In the article Manipulation complexity in primates coevolved with brain size and terrestriality, which can be found in the magazine Nature, authors Sandra A. Heldstab, Zaida K. Kosonen, Sonja E. Koski, Judith M. Burkart, Carel P. van Schaik & Karin Isler, find that there is a plethora of evidence that says otherwise in the terms of manipulation complexity coevolving with terrestriality and brain size.…

    In the film of “The Birds the main characters consisted of Melanie Davis, Mitch Brenner, Annie Hayworth, Cathy Brenner, and Lydia Brenner. The film took place in the 1960s in two parts of California. The way the birds first attacked in the film was similar to the way they first attacked in the short story, in the film a sea gull swooped down and scratched Melanie Davis’ head. The main characters were very concerned with the birds behavior after the first attack and they took all of the signs and warnings seriously. They protected their homes by hanging wooden planks on their doors and windows. In the film police officers did not do anything to stop the attacks, they thought everything was normal. At the end of the film, the main characters manage to escape their home and head back to San Francisco while the…

    Birds in Macbeth

    • 701 Words
    • 3 Pages

    Birds that are not predators symbolize innocence, more specifically childhood. One could say that fowl are fair. Lady Macduff is aghast when she hears the news about her husband leaving Scotland. She tells her son that his father is dead, and asks what he will do. He replies he will live “as birds do, mother”(IV.ii.32). Lady Macduff then comments that he will not fear any kinds of traps, like an innocent bird unaware of its predators and trappers. Banquo and his son Fleance are on their way to Macbeth’s castle for a feast when a group of three murderers ambush the two. While Banquo tries to fend them off he exclaims, “Fly, good Fleance, fly, fly, fly”(III, iii, 17). What he says obviously compares Fleance to a bird, telling him to fly and be free from violence, thus innocent. When Macduff hears about the news of Macbeth killing his “pretty chickens and their dam, At one fell swoop”(IV, iii, 224-225), he calls Macbeth a “hell-kite”(IV, iii, 223). These lines are very dense when it comes to the symbolism of birds in Macbeth. One line establishes birds as horrible things capable of…

    Researchers were amazed more recently, with the discovery of the extent to which New Caledonian crows, attain conceptual abilities, Jeremy Rifkin said “In controlled experiments, scientists at Oxford University reported that two birds named Betty and Abel were given a choice between using two tools, one a straight wire, the other a hooked wire, to snag a piece of meat from inside a tube.” Self-awareness is another aspect, which raises the question of whether these animals’ inferiority affects their mentality.…

    Now when looking at Crow, we have to take a good look at his personality. At first Crow seemed very similar to Yusei, but as we got to know Crow, we quickly learned that he is truly his own person with his own dreams, goals, and ideals. That is shown through the fact that Crow is a hot headed and impulsive person that will do anything to protect those he cares about. This is one of the most important aspects of creating a good character. If Crow didn’t have this flaw, he would have just fallen into the heroic trope that so…
