I have no idea why it's the poor people ,that make the most number of babies ; when they really can't afford any ?
The most successful approach to ensuring a genetic lineage when lower IQ, is to have lots of offspring. This increases the chance for anomolously above average intelligence (average of the parents) in at least one of the offspring, so that a few of a larger number survive.
The most successful approach to ensuring a genetic lineage when higher IQ, is to use that intellect to ensure the survival of a more manageable smaller number of offspring who will typically have the average intelligence of the higher IQ parents . This number is more in line with what natural resources can provide to those offspring to ensure a higher survival rate to a smaller number.
Also of note is the proof that exists that the female passes on intelligence traits, while the male does not have any significant influence on intelligence of offspring (but does pass on other traits like emotional control).
If you run the numbers prior to 200 years ago, you will find that with reproduction vs mortality prior to reproduction, things evened out. Run the numbers in the modern era, and you will find alarming results as mortality in both groups has dropped to near zero, even though reproduction is still higher in lower IQ groups.
