Even children are the result of their environment, what intellectual stimulation they get, what they eat, what they learn and so on. Those environmental differencies are visible in an IQ test. Also reaching puberty earlier or later is also dependant of environmental factors. For example Danish children are reaching puberty earlier and earlier. Maybe they (to use your logic) are regressing and becoming apes?? ---------- Post added 2010-06-27 at 12:52 ---------- Not long ago, there were a lot of people up here in the nordic countries that could not count to seven, nor could they write or read. Today, nearly all people here can write and read and count to seven. And still the genetic makeup of the people is the same. So counting to seven, reading, writing and such things are skills that are learned, they are not genetically inherited.
