    Description / Table of Contents: Zusammenfassung Mit einigen bekannten Ausnahmen, z. B. Sichelzellanämie, kommen genetische Merkmale, die bei den Urvölkern von Jägern und Sammlern ungünstig oder sogar schädlich wirkten, mit niedriger Häufigkeit vor. Genetisch bedingte schädliche Merkmale, die selten unter Urvölkern gefunden werden, kommen jedoch häufiger vor bei Bevölkerungen, die eine lange Geschichte bzw. Vorgeschichte der “Zivilisation” besitzen, wie z. B. in China, Japan oder Europa. Ein Darwinist würde behaupten, daß bei “zivilisierten” Wohnorten solche Merkmale selektiv weniger nachteilig wirken, d. h., daß die selektive Ausscheidung langsamer vorgeht. Anders gesagt: der mit der “Zivilisation” verbundene Wechsel des Wohnortes bildet einen Grund für eine Milderung der Strenge der natürlichen Auslese. Es werden einige genetisch bestimmte oder genetisch beeinflußte Merkmale besprochen, die den Unterschied zwischen den Häufigkeiten (niedrig bei Urvölkern, hoch bei “zivilisierten” Völkern) aufzeigen,. Für 4 solcher Fälle: Farbensinnstörungen, Kurzsichtigkeit, Nasenscheidenwand-Deformitäten und anomale kleine Außenöffnungen der Tränenwege werden die Befunde aus den Bevölkerungen dargestellt.
    Notes: Summary Genetic traits which are disadvantageous or deleterious in “primitive” cultures, of hunters and food gatherers, have very low frequencies in almost all cases. There are a few special exceptions, such as the sickle cell trait. Some deleterious traits under genetic control are rare in “primitive” populations but have fairly high frequencies in populations with long histories or prehistories of “civilization”, such as Chinese, Japanese or European populations. The Darwinist might suggest that these traits have less selective disadvantage, that is, lower rates of selective elimination, in “civilized” habitats; i.e. that the various changes in habitat accompanying “civilization” have caused the rigor of natural selection to relax, in part or perhaps completely. Several cases are discussed of traits under genetic control or genetic influence which demonstrate this phenomenal contrast, between low frequencies among “primitive” populations and high frequencies among “civilized” populations. Population data are presented for 4 such cases: colorblindness, myopia, abnormality of the nasal septum and abnormally small external opening of the tear duct.

    Notes: Abstract Cocaine was administered orally on a double-blind basis to depressed patients and effects on EEG-monitored sleep were assessed. In doses which did not produce consistent effects on vital signs or mood, cocaine significantly reduced total sleep and rapid eye movement (REM) sleep. The REM sleep supression with cocaine administration and rebound upon cocaine discontinuation was dose related; there was a greater effect at higher doses. Two properties of cocaine appear to closely correspond to those of many other drugs which suppress REM sleep in man—enhancement of functional catecholamines and/or high drug-abuse potential.
