Celestina has touched upon the one issue I was abstracting away from, and that is the ability of our colonists to psychologically support the endeavor over the long term. Further the appropriateness of their sociological norms.
Here our assumptions make the world of difference. If we assume a less-than-rigorous selection, I agree with Ex Tanks comments previously, most of these folks will go insane and probably commit suicide, either deliberate or indirectly.
However, I believe that our optimists and the OP have posited some kind of active selection and training. In the last rounds, I have been working with the assumption that they have all had some kind of military like survival training, albeit focused on using neolithic techniques. I assumed further that they would be trained as best one could for the application of such in new environments. And of course, all the prior presumes a high degree of selectivity, as in military elite teams. Having no first hand experience here, I defer to any military folks in re observations about the appropriateness of this model.
So, working on the assumption that these are all (a) volunteers at some level — who think at least that they want to try to recreate civilization (b) selected through rigorous techniques to weed out the obviously too brittle © trained to adapt to the harshness facing them: I still see serious long term problems. Maybe not the first year, maybe not the second year, but in the long run.
I posit the following problems:
Social structure: no matter what the training, the team/group (shall we continue to say 3k or 5k individuals) will still have modern group social structures as their background assumptions. How well will such socialization work — at this scale of at least 500 up to 5k individuals — when they have to break out into roaming hunter gather bands?
Mortality assumptions: how well will the group(s) actually cohere when what I think we have to assume is relatively high mortality begins to kick in? It’s one thing to deal with this in the abstract, but our volunteers are nonetheless psychologically adapted to much lower mortality rates. What happens to group(s) begin to lose members, e.g. Jose and Fernandez get stomped by megafauna? What impacts on subsistence patterns?
Hubris of Science: the group will need to be made up of very proactive, positive people. This contains its own issues. Selection bias in re understanding the new environment and possibly excessive optimism with initial successes may lead to inappropriate choices, including too early fixed or semi-fixed settlement and too high population density.
I foresee the following effects:
(a) Bands will tend regroup for safety and psychological support in numbers environmentally unsustainable in the long term. Further, assuming some attempts at centralized leadership, say on military lines, centralization will impose costs and risks which may outweigh benefits by restricting “roaming area” and imposing communication costs (e.g. runners) which may not be supportable. Inappropriately large h-g bands will raise risk of too rapidly depleting “known” environment/area and raising disease/environmental disaster risk.
A further item in re social structure, and that is tensions in re sex relations. First, women will be much more valuable than men in the long term, insofar as group survival will depend largely on producing a second generation as well as their basic food gathering role. Higher male mortality rates will likely produce a destabilizing gender imbalance. For all the snickering about harems and the like, our group will not likely be really adapted to the idea of multiple mates, which may well be necessary. This will imply tensions and problems in re adjustment which may, at the very least, be presumed to reduce efficiency.
(b) Connected to (a) but also operating independently, there will no doubt be negative reactions to the first wave of mortality. Early mistakes of all kinds, probably when the group(s) initial guard is down — say six months to a year into the project — will produce a wave of fatalities/casualties. I suspect that this will in turn tend to create a risk averse environment. Also note of course the connection with gender imbalance above. When we leave aside fantasy jollies, this could be a non-trivial problem. Effects will probably tend to go in the direction of foregone mobility and a tendency to err in the direction of settlement (already a sub-conscious bias on the part of our folks) which in the long run may be fatal due to issues of resource exhaustion as well as disease issues.
© In regards to Hubris, I see the following issue: on the assumption we are working on some alternate Middle East/ancient pre-man Middle East we are looking at an environment with some serious degree of variability. I believe that the unconscious developed world bias to ignore variability or to assume stability (for we have largely stabilized our environment) is likely to get our group in trouble over the medium term.
Let us presume they arrive at the beginning of a five year wet cycle. They get to know their chosen area fairly well, and suffer only moderate mortality rates. Natural surplus in the wet period is enough to support a quasi-settled life. After the first year or two, our 5k group has colonized the area, and their guard slips. Whether with centralized control or not, they slip into a quasi-settled lifestyle living more or less at the border of the wet-cycle environment’s capacity with supportable but only in this cycle population density. But this seems fine, they believe they have mastered their environment, marginal progress is being made to domestication of some plants and animals (say goat precursors). Their goal is, after all, settlement.
Then year six, severe dry season hits, taking them unawares. Moderate storage from prior years takes them through to year seven w/o elevated mortality, but group is weakened. Drought continues (perhaps a three or four year cycle). Spreading out is difficult as they have not adequately come to know their out-region environment and they now face severe competition with wild-life, including predatation from pressed predators such as lions, perhaps mega-predators. Fish and other caloric income plunges and river/coastal predators also step up pressure. We could see an absolute population collapse right here. At the very least, they lose their hard won gains, much time and energy lost, and the groups will have to make an emergency dispersal, possibly permanently losing contact or dying out in new stressed environments.
In essence I see an elevated risk of medium term underestimating environment risk leading to a population crash.
The final issue is group cohesion. Clearly in connection with all these stresses we can not rule out the mega-group breaking up into hostile bands some years down the road, even with military discipline. Tensions of differences in re survival choices, ‘relationship’ driven tensions etc. will have to be dealt with without a real authority super-structure. As such, re- emergence of pre-modern clannishness is highly likely in the long run, further undermining efforts to a quick transition to non-hunter-gatherer life. Put this in the context of the drought scenario described above and I think we can all see the recipe for disaster.
I don’t believe that the above is even particularly pessimistic, for I presume they do survive the scenario, but with a shattered social structure. Future of tech-civ? Thousands of years away.
Added comment in re presence of other hominids:
After some consideration, I believe that we should not assume that this changes the equation very much. Badtz has made the assumption that they could be enslaved and put to work. I see several issues: depending on who they are (I assume at least homo erectus) they may be more dangerous for our group than the reverse. At least, I do not think we can assume there is automatic superiority.
Second, in re enslavement, this presumes (a) ability to use slaves effectively (b) ability to control. In re (a), we should recall that at the hunter gatherer level, we are working with little to no surplus carried over. It is difficult to imagine being able to use slaves economically to produce advantage. They are as likely to be a drain as not, except if a conscious policy of working them to death was adopted. The problem with this is (b) ability to control and whether effort to control yields benefits — in a hunter gatherer context — which exceed costs in terms of time. Further, a policy of working slaves to death implies a degree of de- socialization in re 21st century norms with dangerous implications in re group psychology/in group dynamics.
Per Patterson, Slavery and Social Death pre-settled/agricultural slavery did not show economic use patterns. Rather it seems to have been religious/death substitute, and in large part was “uneconomic” where it existed, unless understood in terms of increasing the group size and eventual assimilation. In the case of our experiment, I believe the latter is impossible, the former irrelevant.
Final analysis:
Odds for the experiment as per OP, and even allowing for rigorous preparation, run towards zero for recreating civilization rapidly. Even survival is something of a crap shoot, but in the context of allowing for a well-selected and trained group, I think slightly better than even in the long run.
My analysis is that a virgin world settlement successfully recreating industrial society requires significant physical capital to go along with the human capital. Even in this case, historical settlement examples, e.g. early English settlement of North America suggest that risks are high.
This would, however, make an interesting if grim novel if written with strict realism.
