From the essay: 'Professors Mark Hanson and Peter Gluckman published their review of the evolution of puberty in Trends in Endocrinology and Metabolism (Jan. 2006). The authors discuss the various adaptive mechanisms that may influence the early or late onset of puberty and menstruation in human beings, and argue that modern life has allowed a return to the developmental pattern evolved for hunter-gatherer societies.
Over the past 100 years there has been a marked trend for a reduction in the age of menarche. In populations of Northern European origin, the age of menarche is now approximately three years earlier than it was 100 years ago. The trend, write Hanson and Gluckman, “is generally interpreted as being a reflection of improved nutrition and reduced infection in childhood over the past two centuries”. Significantly, the influence of such environmental factors is delimited – puberty will not continue to arrive ever earlier in childhood. The age at which it will ‘naturally’ occur is evolutionarily hard-wired.
The authors write: “We propose that human females evolved to enter puberty at a relatively young age and progressed to reproductive competence at 11-13 years of age. This would have matched the degree of psychosocial maturation necessary to function as an adult in Paleolithic society based on small groups of hunter-gatherers.
.. For the first time in our evolutionary history, biological puberty in females significantly precedes, rather than being matched to, the age of successful functioning as an adult. This mismatch between the age of biological and psychosocial maturation constitutes a fundamental issue for modern society. Our social structures have been developed in the expectation of longer childhood, prolonged education and training, and later reproductive competence. This emerging mismatch creates fundamental pressures on contemporary adolescents and on how they live in society.”

to Adulthood. Breasts, Erections, Menstration, Hair, Education'.
The main sexuality pages on the evolution of
our diverse sexual behaviors have good content and are well worth browsing
(see links at top of page). And the list of related
sexuality terms that people actually search is informative (to say
the least!).
Want to be Involved? Join us in this research,
which provides an excellent opportunity to present to the world the latest
knowledge about the thing we all find most interesting - sex! The work
will not just benefit humanity, it will profoundly enhance your own sexuality
as you learn more about our complex and diverse sexual evolution.
We seek help in finding the latest scientific
(evolutionary) research on our biological and cultural sexual evolution
and distributing content (overviews / summaries) to relevant pages.
This site is well respected. We are listed as
the Top
Philosophy Website on the Internet with around 500,000 page views each
week. So your contributions will be seen and read, and will be providing
humanity with a great source of wisdom about a very important subject (that
currently suffers due to cultural / religious myths).
If you would like to be involved (or have comments about this website) please write to us using the form lower on this page. Many thanks! Karene
Analyse
any human emotion, no matter how far it may be removed from the sphere
of sex, and you are sure to discover somewhere the primal impulse, to which
life owes its perpetuation. ... The primitive stages can always be re-established;
the primitive mind is, in the fullest meaning of the word, imperishable.
... Mans most disagreeable habits and idiosyncrasies, his deceit, his cowardice,
his lack of reverence, are engendered by his incomplete adjustment to a
complicated civilisation. It is the result of the conflict between our
instincts and our culture. (Sigmund Freud)
