Ah, but the environmental context of teenagers in most developed nations is
highly conducive to widespread sex and reproduction. The parental
investment of any particular person is not that important given a economic
and social structure that largely supports young and single parents in ways
in which our ancestors couldn't have done.
In Britain, which has very high teenage pregnacy rates compared to most
parts of Europe, there was a moral panic a few years back about teenage
girls getting pregnant just to get their own council flat, which was
massively overblown (despite their undoubtedly being some who did do just
that). In conditions where the state supports the pregnant poor, there's
little incentive for people to be choosy.
Interestingly, there's that issue though of low birth rates in developed
nations overall- how come given the material resources available to most
people in rich countries we don't have more kids? And how come the richest
people tend to have the fewest number of kids? Some say it's to do with the
massive social investment that it takes to become rich, and spreading those
resources between lots of kids threatens all of their chances (e.g. paying
for their educations etc. etc.). So whilst genetic factors suggest that the
adaptive strategy is to have lots of kids when you have lots of resources,
the cultural "survival" strategy supresses this.
Perhaps this is why teenage pregnancy is both a major taboo, and something
that happens a fair bit. In the first case this is because older people
recognise the problems of achieving the desired social status (for both
young parent and offspring) which gets you the resource awards when you have
a kid or two in tow, and because recognising that takes knowledge that only
comes with extensive learning and experience which teenagers don't have.
