There is not a simple answer. It depends on few factores at least, least
of which is that one cannot be good at everthing. It takes to much time
to do so, so we specialise.
Indeed, I know exactly why I am a bad speller. Again it goes back to
>(esp. British people) yet
Clearly this is not supported by any evidence. Abilities, by and large
are pretty uniformly spread amongst the races. I agree that there are
some differences, but your basic claim here is quite nonsense.

No. Not at all.

You need to self evaluate your earlier childhood. Most things have
explanations, if you look hard enough.

This is pure speculation on your part. There is nothing definite about

Ite just not as simple as this.

This is pretty much incorrect. For starters, I am actually quite vocal
in support of genetics, and have looked at this in some detail. Indeed,
two simple assumptions explain much about emotion and behaviour, e.g.
1 Traits are continuously and randomly generated, which are subsequently
selected by the environment.
2 Traits are passed on to offspring.
Traits can be either genes, i.e. physical characteristics, or memes,
which are concept/idea characteristics.
The basic assumption that evolution has programmed relatively fixed
abilities into different individuals is fundamentally flawed. This would
be to limiting. Evolution is much more rich and complex than this.
Individuals characteristics are controlled strongly by the environment.
Characteristics, are in essence, software programmable. For example,
most of us feel a bit sick if we see someone get their head chopped off.
Clearly then, there is a *genetic*, physical mechanism that manifests
itself as the emotion "disgust". However, if for example, one was to see
a man with an axe just about to chop of the head of ones own child, and
you blew his brains out first, there might well be no feeling of disgust
at the blood at all. So, it can be seen that the environment is a key
factor in telling one how physical characteristic actually manifest
themselves. The most classic case are the insects that are born with
different colours depending on the temperature.
Certainly, I agree that there must be a select few that excel due to a
preferential genetic disposition, that is, after all part of the basis
of survival of the "fittest". However, the genetic differences between
most individuals are simple not that marked to make a significant impact
on the actual differences observed.
Overall, you need to do some serious reading on the link between
genetics and the enviorment.
