In Diskussionen über Männlein und Weiblein das gefürchteste Totschlag-Argument: „Bei den Höhlenmenschen lief es halt so …“. Und deshalb auch dieses Zitat:
Why did cave-men live in caves? Caves are rare and expensive pieces of real estate. If you find one, it is likely to be already inhabited, thus you need to kick out the old tenants (bears?) in order to move in. Then you have to defend it from others who also want this nice piece of property. And it is difficult to defend a cave – it has one entrance – the rest is a trap. If the intruder is really dangerous you have two options: to go out and be killed outside, or remain inside and get killed in the cave.

Andere Einsichten, wieso es Eulen (= mich) und Lerchen (all die anderen da draussen, inkl. meiner Freundin) gibt:
A classical sociobiological just-so story posits that this kind of individual variation on the lark/owl continuum had an adaptive function, namely to ensure that at every time of night at least one member of the tribe was awake. Thus some stood guard early in the night, others late in the night, listening to the sounds of the jungle (or savannah, or whatever) while the midnight break is thought to have been used for copulating with whomever also happens to be awake at the time – this was before the social invention of sexual monogamy.
Mag man diesen Höhlenmenschen-Erklärungen noch so abgeneigt sein – zur Zeit ist dies die plausibelste Erklärung für unterschiedliche Schlaf-Rythmen …
