Dear Christophe,<br>
<br>
My approach to pre-human evolution is a very narrow but general one, <br>
namely, the specifically human evolution of symbols. As any other <br>
organism, thermodynamically, humans are metastable, active systems far <br>
from equilibrium. Minor internal or external effects may trigger <br>
macroscopic activities by releasing energy that had been accumulated <br>
internally.<br>
<br>
To those small triggers belong neuronal signals which, as a result of <br>
mental processes, seem to play a much more important role in humans than <br>
in any other species. Any activities, including sexual ones, are started <br>
or stopped by decisions which release an associated trigger for, say, a <br>
well-structured cascade of muscle contractions or the like.<br>
<br>
Such decisions are the result of alternative prediction models for the <br>
expected future impact of the perticular decision. Many such prediction <br>
models are genetically inherited and result from phylogenetic experience <br>
of all successful ancestors, other such models from the individual <br>
ontogenetic experience during the personal life, and finally, rather <br>
specific for humans, certain models result from cultural experience by <br>
symbolic communication with other humans by books, diaries, chats etc.<br>
<br>
Prediction models associate weights to the alternative potential <br>
activities. Comparison of those weights results in a decision. From <br>
introspection we know that inherited weights include pain, anxiety, <br>
happiness or pleasure, as "qualia", and this may apply similarly to all <br>
higher animals.<br>
<br>
To survive on the ground, hominins developed intense social cooperation, <br>
controlled by symbolic mutual communication and advanced mental <br>
information processing. The progress of such capabilities dominated <br>
hominin evolution, including the later development of science and <br>
technology with its sophisticated prediction models in the form of <br>
cooking recipes, mathematical theories or technical construction plans.<br>
<br>
For more details, please see "On the evolution of symbols and prediction <br>
models", <a href="https://urldefense.com/v3/__https://doi.org/10.1007/s12304-023-09528-9__;!!D9dNQwwGXtA!X0UPW5W1m15CIzAVuH6Vr2hHuvgNIaWUBWu2GwmvOKFAVYDfgEkW-F202WbVoxKGd1e-HxoRZ8EdQKQ-gJBtZT4qSJw$">

>_). To limit that mental <br>
>> suffering our ancestors may have been obliged to look for new anxiety <br>
>> limitation processes. Pleasure, as naturally limiting anxiety, could <br>
>> have been a candidate for various developments in that perspective. <br>
>> More precisely, it was possible for our ancestors to extend sexual <br>
>> pleasure by developing its occurrence independently of reproduction <br>
>> concerns. Developing and amplifying sexual relations could have been <br>
>> an easy, and quite natural, ?way for our ancestors to limit the <br>
>> anxiety increase they were facing.<br>
>> What is proposed here is that our ancestors have capitalized on <br>
>> sexual pleasures to develop sources of anxiety limitation. This could <br>
>> have led pre-human sexuality to become highly ritualized and very <br>
>> different from chimpanzee?s sexual behaviours.<br>
>> For instance, here are some human sexual specificities the <br>
>> implementation of which could illustrate the search for more pleasure <br>
>> by our pre-human ancestors:<br>
>> -?No mating season, sexual pleasure possible at any time. Permanent <br>
>> breast as signal.<br>
>> - Sexual behaviors embedded in symbolic, emotional, and cultural <br>
>> systems. More emotional sharing by face mating.<br>
>> - Sexual pleasure layered with self-consciousness, fantasy, <br>
>> attachment, anxiety, and meaning.<br>
>> - Sexual pleasure more intense as psychologically deeper, more <br>
>> elaborated and more cognitively amplified.<br>
>> The above hypothesis brings sexuality and anxiety limitation to be at <br>
>> the forefront of human motivations. This subject is not new but <br>
>> deserves being developed a bit more, I feel.<br>
>> Thanks again Rainer for having introduced it.<br>
