A new member of the family: Aristoteles II

Aristoteles (Greek: Ἀριστοτέλης, Aristotélēs) is 10weeks today, and is named after our old dog Ari (which was a short form for Aristoteles) as well as the philosopher Aristoteles (in English known as Aristotle) who is known to be the funder of the science biology.

Aristotle's classification of living things contains some elements which still existed in the nineteenth century. What the modern zoologist would call vertebrates and invertebrates, Aristotle called 'animals with blood' and 'animals without blood' (he was not to know that complex invertebrates do make use of haemoglobin, but of a different kind from vertebrates). Animals with blood were divided into live-bearing (humans and mammals), and egg-bearing (birds and fish). Invertebrates ('animals without blood') are insects, crustacea (divided into non-shelled – cephalopods – and shelled) and testacea (molluscs). In some respects, this incomplete classification is better than that of Linnaeus, who crowded the invertebrata together into two groups, Insecta and Vermes (worms).
