Footnote 138: Arist. _de Caelo_, Β, 13. 295 b 10, εἰσὶ δέ τινες οἳ διὰ τὴν ὁμοιότητά φασιν αὐτὴν (τὴν γῆν) μένειν, ὥσπερ τῶν ἀρχαίων Ἀναξίμανδρος· μᾶλλον μὲν γὰρ οὐθὲν ἄνω ἢ κάτω ἢ εἰς τὰ πλάγια φέρεσθαι προσήκειν τὸ ἐπὶ τοῦ μέσου ἱδρυμένον καὶ ὁμοίως πρὸς τὰ ἔσχατα ἔχον. That Aristotle is really reproducing Anaximander seems to be shown by the use of ὁμοιότης in the old sense of “equality.” [Sidenote: Animals.] 21. We have seen enough to show us that the speculations of Anaximander about the world were of an extremely daring character; we come now to the crowning audacity of all, his theory of the origin of living creatures. The Theophrastean account of this has been well preserved by the doxographers:— Living creatures arose from the moist element as it was evaporated by the sun. Man was like another animal, namely, a fish, in the beginning.—Hipp. _Ref._ i. 6 (R. P. 22 a). The first animals were produced in the moisture, each enclosed in a prickly bark. As they advanced in age, they came out upon the drier part. When the bark broke off,[139] they survived for a short time.—Aet. v. 19, 1 (R. P. 22). Further, he says that originally man was born from animals of another species. His reason is that while other animals quickly find food by themselves, man alone requires a lengthy period of suckling. Hence, had he been originally as he is now, he would never have survived.—Ps.-Plut. _Strom._ fr. 2 (R. P. _ib._). He declares that at first human beings arose in the inside of fishes, and after having been reared like sharks,[140] and become capable of protecting themselves, they were finally cast ashore and took to land.—Plut. _Symp. Quaest._ 730 f (R. P. _ib._). Footnote 139: This is to be understood in the light of what we are told about γαλεοί below. Cf. Arist. _Hist. An._ Ζ, 10. 565 a 25, τοῖς μὲν οὖν σκυλίοις, οὓς καλοῦσί τινες νεβρίας γαλεούς, ὅταν περιρραγῇ καὶ ἐκπέσῃ τὸ ὄστρακον, γίνονται οἱ νεοττοί. Footnote 140: Reading ὥσπερ οἱ γαλεοί for ὥσπερ οἱ παλαιοί with Doehner, who compares Plut. _de soll. anim._ 982 a, where the φιλόστοργον of the shark is described. See p. 74, _n._ 141.
