<p class="MsoNormal"><span lang="EN-GB">Dear Dr. Feistel,</span></p>
<p class="MsoNormal"><span lang="EN-GB">Thank you for this
stimulating and
conceptually ambitious contribution. Your integration of
ritualisation theory,
biosemiotics, and hominin evolution offers a provocative
framework for
interpreting permanent human breasts as ritualised sexual
symbols emerging from
breastfeeding as a prior use-activity. Framing sexual morphology
and behaviour
as components of evolving information systems is particularly
compelling within
the FIS context.</span></p>
<p class="MsoNormal"><span lang="EN-GB">In the spirit of
constructive dialogue, I
would like to raise a few points that may help clarify and
further strengthen
the proposal:</span></p>
<ol style="margin-top:0cm" start="1" type="1">
<li class="MsoNormal"
style="mso-list:l0 level1 lfo1;tab-stops:list 36.0pt"><span
lang="EN-GB">Causal sequence and empirical grounding.<br>
The proposed chain, from bipedalism to earlier weaning,
suppression of oestrus swelling, coercive mating dynamics, and
the evolution of permanent adipose breasts, is theoretically
coherent but empirically demanding. Each step implies specific
selective pressures that would ideally require converging
support from fossil, comparative primate, developmental, or
genetic evidence.</span></li>
<li class="MsoNormal"
style="mso-list:l0 level1 lfo1;tab-stops:list 36.0pt"><span
lang="EN-GB">Proto-use activity and ritualisation.<br>
The hypothesis that close visual or tactile “inspection” of
nipples or genitals functioned as an adaptive
fertility-detection activity later ritualised into courtship
behaviour is intriguing. Comparative data from extant
primates, however, would be important to substantiate this
proposed transitional stage.</span></li>
<li class="MsoNormal"
style="mso-list:l0 level1 lfo1;tab-stops:list 36.0pt"><span
lang="EN-GB">Menstruation and menopause within life-history
theory.<br>
The suggested link between contraceptive behaviour, recurrent
futile ovulation, menstruation, and a lowered menopause age
appears to depart from prevailing life-history explanations,
including standard formulations of the grandmother hypothesis.
Clarifying how this model complements or revises existing
frameworks would sharpen its theoretical positioning.</span></li>
<li class="MsoNormal"
style="mso-list:l0 level1 lfo1;tab-stops:list 36.0pt"><span
lang="EN-GB">Extension to contemporary social phenomena.<br>
While evolutionary legacies may shape behavioural
predispositions, present-day sexual conflict and demographic
patterns are strongly mediated by cultural, economic, and
institutional factors. A multi-level explanatory perspective
may therefore help avoid possible biological overextension.</span></li>
</ol>
<p class="MsoNormal"><span lang="EN-GB">Despite these open
questions, the strength
of your contribution lies in proposing a unified causal
narrative rather than
isolated adaptive accounts. By situating human sexual morphology
and behaviour
within an informational and semiotic framework, you invite
precisely the kind
of interdisciplinary exchange that FIS aims to foster.</span></p>
<p class="MsoNormal"><span lang="EN-GB">I look forward to further
elaboration and
discussion of the empirical and theoretical implications of this
model.</span></p>
<p class="MsoNormal"><span lang="EN-GB">Best regards,</span></p>

<p class="MsoNormal"><b style="mso-bidi-font-weight:normal"><span
lang="EN-GB" style="mso-ansi-language:EN-GB">Emergence of
Human Sexual Behaviour</span></b></p>
<p class="MsoNormal"><span lang="EN-GB"
style="mso-ansi-language:EN-GB">Natural evolution invented
symbols as information carriers, universally exploited by
any living being in various forms. As a rule, self-organised
symbols appear by ritualisation, a qualitative transition
from behavioural use-activities to related
signal-activities, as discovered by Julian Huxley in 1914.
Numerous novel and unparalleled symbols emerged in the
course of anthropogenesis. Sex symbols, or courtship habits,
are typically unambiguous intra-species information tools,
governing the species’ reproduction behaviour by starting
and terminating the mating season.</span></p>
<p class="MsoNormal"><span lang="EN-GB"
style="mso-ansi-language:EN-GB">Permanent adipose mammary
glands recognised as sex symbols are unique to humans only.
If those emerged by a ritualisation transition, what may
have been the use activity they had originated from?
Anatomically, the most likely such activity is
breastfeeding. However, lactating female mammals are
generally infertile and typically avoid any mating
activities in favour of their childcare. “The verdict is
still out on why the permanent breast evolved in humans”
wrote Deena Emera yet in 2024.</span></p>
<p class="MsoNormal"><span lang="EN-GB"
style="mso-ansi-language:EN-GB">Fossil and genetic evidence
is consistent with the plausible hypothesis that the last
common ancestor (LCA) of humans and great apes lived about 7
million years ago and was similar to recent chimpanzees. The
sexual behaviour of the latter, however, is very distinct
from that of humans. Female chimps breastfeed their
offspring, carried on their back, for about five years.
Premature weaning poses a high lethal risk to the helpless
infant. After weaning, females develop a prominent
anogenital swelling as a sex symbol that invites males to
mate. It is exclusively then that males show relevant sexual
interest, and preferably in old “ugly” females. How may
human sex life have evolved from such foreign roots during a
relatively short period of history? Likely, the radical
change was enforced by violent selective pressure.</span></p>
<p class="MsoNormal"><span lang="EN-GB"
style="mso-ansi-language:EN-GB">When the LCA gradually
turned to bipedalism, carrying older, heavier infants on the
back became impractical and weaning occurred earlier, with
increasing risks for the offspring and generally reduced
reproduction rates. Females suppressing the fertility
swelling protected the toddler by preventing early
pregnancy. Males responded with permanent sexual interest
also in non-swollen females. Females reacted with repulsive
frigidity, males in turn with coercive mating. Already from
a distance, ostentatious adipose breasts, perfectly
imitating lactating ones, prevented coercive male
approaches, who in return started closer visual, manual or
oral inspection of the nipples in order to check fertility
and reveal the possible fake. Successful contraception by
fertile females caused periodic futile ovulation and
subsequent regular menstruation. The resulting ovary
depletion lowered the menopause age into the lifespan, so
that old females became infertile and could take care of
their grandchildren when the mother became pregnant too
soon. This grandmother effect raised the reproduction rate
substantially, supporting enhanced migration pressure on the
younger generation. The previous inspection of female
nipples and genitals was no longer a necessary use-activity
and turned into a courtship habit of humans by a
ritualisation transition, similar to that of waterfowls
originally discovered by Huxley. </span></p>
<p class="MsoNormal"><span lang="EN-GB"
style="mso-ansi-language:EN-GB">This is a speculative
narrative of how the ritualisation of human sexual behaviour
was possibly caused by the transition to bipedal gait. The
genetic heritage of those old days may still influence the
social behaviour of modern humans and may be part of
contemporary sexual conflicts, such as sexual harassment,
high divorce rates or declining birth numbers in liberal
societies. Causal mental models are key for understanding
the origin of such problems rather than just lamenting and
deprecating their symptoms. Finding suitable compromises
between mutually inconsistent sexual interests may provide a
challenging but promising future solution, rather than
implementing restrictive, one-sided patriarchal or
matriarchal social suppression systems. </span></p>
