Howard, I really love this!
I had some alternative--or actually, additional thoughts--not ones I necessarily want to champion, but nonetheless I feel like sharing: Perhaps PTSD is adaptive for the individual and ultimately the group. A young hunter is out on the savannah and his brother/kin is savagely destroyed by lions, say. He might experience all sorts of emotions in response to witnessing this, perhaps the symptoms of PTSD. The emotions (as par Randy Nesse et al.) guide his behavior--i.e. staying at 'camp' not going on hunts, ruminating over and over the scene, etc etc. The symptoms like memory loss are maybe just "mind-spandrels."
The hippocampus goes into obsessive overdrive on the old memories at the expense of new ones. The hippocampus is still "carrying" the event. So...maybe the memory loss just represents a reorganization of the brain. A traumatic event, of course, can be life-altering. It takes a lot of brain power/energy to restructure neuronal morphology. People literally change after such events. Something new is being learned very quickly: a whole new way of being. "Don't charge at lions. Don't trust men from the neighboring tribe. Don't wear bones when hunting." * For such a thing to happen, the hippocampus can't be bothered with forming new memories. So the symptoms are the means to, and also the signs of, those changes. There's no doubt that a person suffering from the symptoms of PTSD would have garnered support, fear, and elicited a whole host of behavioral responses--as today. And that indeed an individual with the symptoms of PTSD would have been a marker--a reminding factor. Members of the group's physiology wouldn't have gone thrrough such dramatic and intense changes like the individual, but they (and their physiology to some degree) would be influenced in some fashion, surely.
Another thought. I don't actually know the statistics or have any data on this stuff, I can only speak from impressionistic observation and experience. But it seems to me that people who suffer with the symptoms of PTSD eventually stop suffering. ** The changes finally get wired--so they're no longer signposts for the group in that way...Though the group will have experienced the person in that state for a while and have their new state as reminding factor, too.
Anyway, to answer question: tremendous survival value for individual and group if the symptoms lead to 're-education' and changes in personality, behavioral response, etc etc.
*Magical thinking and OCD are related to these things and also were quite adaptive.
** Meds, of course, are very helpful...but I imagine that the change that mother nature has programmed the suffering person to go through doesn't actually happen with meds. And, I actually have no particular feeling on whether one way is better or worse..I don't have a romantic view that suffering through the symtoms of PTSD in today's world could be all that beneficial to the individual. I would look at it on a case-by-case basis, I suppose. (I generally take the view that people (unless they pose a threat in some way to self or others) need to experience such emotions for a tiny little while without meds--even PTSD. (I suffered with such symptoms (and then some!) for about 4-5 years without meds, btw. Not something I would advise everyone to do!!!)
More to think about and to write, but have to run!

If you have PTSD (post traumatic stress disorder), your hippocampus works poorly and you have a lot of trouble storing new memories. It’s your old memories that prevail, the memories of the horrid experience that produced your trauma to begin with. Is this fixation with a danger in the past helpful to your personal survival? Or is it helpful to something else—to the survival of society? If you suffer from PTSD, does your brain and body inflict that suffering every day to turn you into a signboard--a walking warning of danger to the rest of us?
Ted Coons proposes that us old folks lose our ability to remember recent events but still hang on to memories of our distant past for a reason. Not a reason that helps us aging elders, but a reason that helps the collective mind, the mass intellect of society. We elders, Ted thinks, are storage jugs keeping antique memories alive not for the sake of our personal survival, but for the sake of the younger folks who’ve had no opportunity to experience or remember the days when we elders were young and vigorous. Those youngsters have had no chance to remember the problems and solutions of our childhoods way back when, the problems and solutions of an earlier generation or two or three.
Can PTSD victims serve a similar function, as danger markers for those of us who’ve never experienced the horrors that the past-obsessed and present-challenged PTSD patients remember far, far better than they’d like? Are they walking warning signs to the rest of us? Are they, like all of us, disposable modules in the mass learning machine of culture, in the parallel distributed intelligence of the collective brain?
