Да мне-то откуда знать? Не знаю я ничего ни про разум, ни про верблюдов.
Но на моей способности иметь потомство это никак не отразилось.

Да легко. Просто они вместо думания разных мыслей занимались именно деланием потомства.

... argument against a substantial heritability for IQ differences neglects three special considerations:
1. the help offered to lower-IQ people by individual benefactors, churches, charities and governments;
2. the economic demand (till very recently) for manual labour and basic soldiering and domestic skills; and
3. the rewards available for criminality (even when the criminal is detected, if proceeds have been transferred to kin, and if there are few penalties for a criminal's biological relatives).
So perhaps there need have been no general relation between IQ and fertility over at least the past century. Whatever may have happened across evolutionary history, intellectual limitations could easily have remained perfectly heritable across recent generations in the West; and, since 1970, at least in the USA, out-of-wedlock births have risen sharply among girls and women of below-average IQ (see Chapter IV).(21) In short, g has not lately been a fitness character: genes for the full range of IQ differences can easily have been passed on.

Иначе говоря вклад наследственности и окружающей среды в уровень интеллектуального развития примерно одинаков и один неотделим от другого
In Minneapolis, during the 1980's, Tom Bouchard, David Lykken and co-workers brought together the most widely separated pairs of MZ twins to have been studied by psychologists.(27) Quite often one of the twins, or a friend, wrote in to Minneapolis after reading an article in a newspaper about the project or seeing an advert. Twin pairs were offered a week's accommodation and hospitality in return for co-operating in full medical and psychological examinations. The 48 Minnesota MZa pairs were around age forty at the time they were interviewed and tested; and they had typically been separated for some twenty years - from around five months after birth. The pairs' degree and timing of separation turned out to bear no relation to their correlation in overall IQ Their within-pair IQ correlation of .78 was as high as the 40-year test-retest correlation for IQ (see Chapter 1). The twins' home environments had in fact correlated modestly, at .27, for social class; but since the adoptive fathers' SES levels correlated merely at .17 with the eventual IQ's of the twins that they had reared, the similarity between the twins in home SES could not begin to explain their similarity in IQ.
Within normal demographic and environmental ranges of the mid-twentieth century West, the MZa correlation indicates a broad heritability of IQ of around 75%. Spelling this out, some 45% of population variation arises from genetic factors that can be transmitted from parents to children [i.e. from narrowly heritable factors that can be subjected to selective breeding], and a further 30% arises from genetic factors that are not conventionally [i.e. narrowly] 'inherited'. The remaining 25% of population variance in IQ occurs because of the environmental differences between homes (10%), other environmental influences (5%) and sheer test unreliability (around 10%).

Italians urged to switch off TVs
Television networks in Italy are facing a nationwide weekend walkout - not by staff, but by unhappy viewers...
The strike's organisers, campaign group Esterni, have arranged discounts at a range of venues for people who bring their remote controls with them...
Television is one of the principal causes of dullness and isolation, and is a drain on precious commodity of human time, according to the Esterni website...
Italian television has come under the spotlight recently regarding who controls it...
Protesters took to the streets earlier this month after the Senate backed a bill that will essentially allow Italian Prime Minister Silvio Berlusconi to strengthen his hold on the media.
