狗比貓更聰明

狗比貓更聰明

牛津大學(xué)的科學(xué)家們稱，“人類最好朋友”的智力在數(shù)百萬(wàn)年的進(jìn)化速度要遠(yuǎn)超不怎么合群的貓。

先前的觀點(diǎn)認(rèn)為貓要狗聰明，因?yàn)樗枰年P(guān)注度更低，但研究人員發(fā)現(xiàn)，由于貓不怎么合群，貓的大腦要小得多。

科學(xué)家們首次畫(huà)出了各種不同哺乳動(dòng)物的大腦在六千萬(wàn)年間的演變圖貓和狗哪個(gè)智商高，確定了它們大腦變化的巨大差異。他們發(fā)現(xiàn)，動(dòng)物大腦的體積與其身體其它部分、它的社交程度有聯(lián)系。

研究分析了500多種活著的動(dòng)物和哺乳動(dòng)物化石大腦和身體體積的數(shù)據(jù)。猴子大腦的增大幅度是最大的，其它動(dòng)物依次是馬、海豚、駱駝、狗。研究發(fā)現(xiàn)有相對(duì)更大大腦的哺乳動(dòng)物群體傾向于生活在穩(wěn)定的社會(huì)群體中，諸如貓、鹿、犀牛等更為孤獨(dú)哺乳動(dòng)物的大腦增長(zhǎng)幅度在同一期間要慢得多。

先前的研究稱，相對(duì)于身體體積的大腦增長(zhǎng)速度的規(guī)律在所有動(dòng)物種類中都是一樣的。在《國(guó)家科學(xué)院院刊》發(fā)表的這一研究報(bào)告推翻了那一觀點(diǎn)。研究表明貓和狗哪個(gè)智商高，不同哺乳動(dòng)物種類的大腦增長(zhǎng)模型存在著很大的不同，不是所有哺乳動(dòng)物都有更大的大腦。研究暗示，喜歡社交的動(dòng)物要思考更多東西。

主持這項(xiàng)研究的蘇珊妮-舒爾茨稱：“狗一直被認(rèn)為是更加喜歡社交的動(dòng)物，而貓喜歡獨(dú)自玩。但看上去互動(dòng)對(duì)于大腦是有益的，并擴(kuò)展至其他物種貓和狗哪個(gè)智商高，就像我們自身。我們比猴子和猩猩更為社會(huì)化，這種共處的能力幫助我們獲得了地球的主導(dǎo)權(quán)。”
