>From what I understand, prenatal stress during certain fetal critical
periods can cause the mother's hormonal levels and ratios to
fluctuate, resulting in an increased likelihood of homosexual
orientation in the child. This makes evolutionary sense; if the
environment is hostile enough to cause hardship-induced stress to
the mother, it is likely (the rule - though periodically broken - being
environmental inertia) to be rough on succeeding generations.
Individuals who would not have children of their own and could
therefore devote resources to the well-being of their siblings'
children would help sustain a genetic line through these times; when
the environment improved and stress dscreased, so would the
homosexual percentage of the population. I believe a study was
done in Germany with children born in and immediately after the W
W II period.
