evolutionary advantage of overpopulating

10.14: pol/overpopulation/evolutionary advantage for the poor:

. not only are the poor losing more children to sickness,

they may also need to compensate for losses from

implied survival tactics of the culture .

. often the only way to spread genes of the poor

is to send out pioneers to invade areas already populated;

and, because this style of invasion is so dangerous,

it can only succeed when large numbers are involved .
