"Over a decade ago, "all human behavioral traits are heritable" was stated as the first law of behavior genetics". A new study looked at whether trust was affected by genetics.

The authors found that "genetic influences are smaller for trust, and propose that experiences with or observations of the behavior of other people shape trust more strongly than other traits".

    wrong way around! Exons are the coding (i.e. turned into amino acids/protein) and the Introns are the spacing. Note, despite the comment misconception, many(!) biologists never really thought it was "junk DNA", since biology is necessarily quite conservative with resources. However, not knowing what is does specifically, gets communicated to the outside world as "junk". We now now it is really very important.

    There is no correlation between number of genes and organism complexity (I think this is called the C-paradox).

    The mechanism of alternative splicing is one such way in which greater complexity is obtained from few genes. The same stretch of DNA can produce different proteins, and these proteins can also be modified to function in different roles.

    Look around the natural world, and complex "preprogrammed" behaviour is everywhere. It may be something that is a "threshold" effect - you need a certain amount of "complexity" to get certain forms of intelligence, say. Just rambling...
