There is a magazine called National Geographic (commonly known as National Geographic) (I have already mentioned the magazine several times on this blog).。In its July 2023 issue (latest issue)、Humans as “tool-using animals”、Follow the chimpanzees、3The parrot was added as the second animal.、Although it is a small article, it is reported。
Experiments conducted at the University of Veterinary Medicine in Vienna, Austria are introduced.。The intelligence of parrots has been known for a long time.、As an animal that uses tools、Darwin confirmed this in the Galapagos.、Including an example of a bird called a finch using a tool to dig out insects from a tree.、Already known in many varieties。
What are you doing now?、That's what I thought when I read it、Differently use two types of tools depending on the situation、"Use as a set" as needed。This can be done、Until now, it was thought that there were only humans and chimpanzees.。That's fine too。A similar point has already been pointed out with regard to language ability.、Don't just imitate something like the so-called "parrot"、Understand the meaning of language、I can only think that it is responding、Many examples of high intelligence have been reported.。
As an example from a certain book、In an experiment to teach arithmetic to chimpanzees, ``two add two equal'' ?(What is 2 plus 2?)、A parrot in the next room tapped on the wall and answered "Four".、There was this。Surprised, the researchers tried different numbers and found that they were all correct.。repeat over and over again、While teaching chimpanzees functions between numbers (arithmetic)、それをじっと隣室で聴いていたオウムが、その関数を理解してしまったとしか考えられないということですよね。ただのオウム返しとはまったく次元の異なる能力ですよね。If you think so、そのくらいは当然、本当はもっとすごいんじゃないですか？と言いたいような気さえします。
But、では他の動物は頭が悪い、と一概には言えないでしょう。because、地球上に棲むすべての生物は現在までの生存競争の勝者だけですから。「頭の悪い」（この言い方自体、人間視点一辺倒の偏見ですが）動物は生き残れなかったはずです。
逆に、人間は頭がいいのでしょうか？戦争は人類進化のための選択肢として、「状況に応じて」「使い分け」ているんでしょうか？数学ができる人は苦手な人より頭がいいんでしょうか？馬鹿な人を選挙で選ぶ人はもっとバカなんでしょうか？―済みません、「反省だけならサルでもできる」というかつての「流行語」を思い出してしまいました。たぶん反省さえできないと思いますけど、ニンゲンという動物は。
