Hahahaha, this article is funny. This explains why migrants from "the 3rd world" can take away jobs in "developed" countries ... we took notes with a pen... not by choice but because most of us could not afford a computer. How ironic.
For species where there's an asymmetry in the parental investment, one of the sexes --the one with the smallest investment-- competes, while the other sex chooses. Thanks a lot Darwin.
Anyone who thinks parenting practices -other than the most extreme- shape behavior should think twice and look at the evidence. The blank slate by Steven Pinker might be a good starting point.
There's plenty of evidence that the effects of parenting are generally smaller than we would like them to be, again with a few exceptions.
