Animals have been hunted and farmed for their fur to make items such as coats and hats. [173] Dyestuffs including carmine , [174] [175] shellac, [176] [177] and kermes [178] [179] have been made from the bodies of insects. Working animals including cattle and horses have been used for work and transport from the first days of agriculture. [180]

Animals such as horses and deer are among the earliest subjects of art, being found in the Upper Paleolithic cave paintings such as at Lascaux.

He criticized the dichotomous taxonomy practiced in Plato's Academy, since much of the time, it is superfluous and “pointless.” [2] He concludes by defending the study of animals as a science as important as that of celestial bodies. [3] Aristotle affirmed that every living being consists of two intrinsic parts: [4] Primary matter (οὐσία)
The earliest animals may belong to the genus Dickinsonia, [2] 571 million to 539 million years ago. [3] Individual Dickinsonia typically resemble a bilaterally symmetrical ribbed oval. They kept growing until they were covered with sediment or otherwise killed, [4] and spent most of their lives with their bodies firmly anchored to the sediment. [5]
