據(jù)美國(guó)《科學(xué)》雜志在線新聞報(bào)道，對(duì)300多幅來(lái)自自然歷史博物館和教科書(shū)中的狗,、馬和羚羊的圖片,，以及動(dòng)物玩具的姿態(tài)進(jìn)行的分析表明，在藝術(shù)家所描繪的四足動(dòng)物中,，有50%的步態(tài)實(shí)際上都是站不穩(wěn)的,。
傳統(tǒng)的“四肢落地模式”認(rèn)為動(dòng)物在運(yùn)動(dòng)時(shí)左后肢先落地，隨后是左前肢,，再后是右后肢,，最后是右前肢。然而如果動(dòng)物真的這樣奔跑,，它們很有可能會(huì)失去重心,，并最終跌倒。研究人員在1月27日出版的《現(xiàn)代生物學(xué)》（Current Biology）雜志上報(bào)告了這一發(fā)現(xiàn),。（生物谷Bioon.com）

Summary
Since the work of the photographer Eadweard Muybridge in the 1880s [1,2], experts know well how quadruped animals walk. All walking tetrapods advance their legs in the same sequence, and only the timing of supporting feet may differ [3,4,5,6]. Given the long time since Muybridge's work, one would assume that this knowledge should be reflected in the depictions of walking quadrupeds made by work of painters, taxidermists, anatomists and toy designers. The postures of legs of walking horses, however, are frequently erroneously illustrated in the fine arts [7]. To see if this also applies to museums, veterinary books and toy shops, we collected hundreds of walking depictions and tested whether or not they correctly display limb positions. We found that almost half of the depictions are wrong. This high error rate in walking illustrations in natural history museums and veterinary anatomy books is particularly unexpected in a time where high-speed cameras and the internet offer ideal possibilities to obtain reliable quantitative information about tetrapod walking.
