So he never tried out his own holo-memiors?

Also this would imply Tom wrote more of them than Harry and the Doctor combined, at which point it's probably Tom's holo-memiors anyways.
This is all consistent behavioral assumptions about a guy who was an ensign for seven years, I think.

Sort of.

You'd see a predator/prey paired relationship lock in such a case. Promptly followed by the predator going extinct because either the species ate all of the prey species or because the prey species successfully outlasted the predator. Promptly followed by the prey species becoming a persistent pest until either the local ecology adapts or is stripped and dies as the former prey species breeds without constraint except food.
No. If the prey can handle their own toxins without dying, something else can deal with their toxins while eating them.

However, almost certainly, you'd see predators becoming specialized to a very specific range of prey in such a situation.
...Since these replies parallel each other I'm responding jointly.

What I'm getting at is that it seems to me that... Well, specialized predator/prey relationships do favor things like parasites or fungal infections. And don't favor large apex predators whose presence would be immediately obvious on a casual biological survey by a lone Starfleet explorer captain.

Parasites and disease germs (fungi, etc.) have short life-cycles and can rapidly evolve resistance to a new toxin. Apex predators, as a rule, don't, so they can't.

You can have a type of insect that "preys" solely on a specific species of herbivore and cannot survive on the blood of other herbivores. Or a type of hostile fungal infection that survives in that herbivore's gut and spreads itself through feces, and does not survive or thrive in other species. But something like a lion isn't going to do very well if it can only safely eat the flesh of one species, and may not even do well if it can only subsist on the flesh of a cluster of closely related species.

Likewise, if most or all large land animals are already toxic, and mutually toxic due to various species getting into toxicity arms races with different species of specialized parasites and infections... It presents a considerable barrier to any one species evolving to prey on other large land animals. Because you don't just have to evolve the ability to chew and digest larger amounts of meat, you have to evolve the corresponding poison resistance. The only time this would be viable is if a cluster of closely related species already had similar blends of toxins, and were thus mutually immune to each other's toxins, making it possible for a predatory species to evolve a sort of pseudo-cannibalistic behavior.

So you could have a species like bears, that can eat a mixed plant/animal diet... But the bears could only prey on other species closely related to bears (i.e. skunks and raccoons), not on unrelated species (i.e. deer, rabbits, and pigs). This would greatly limit the viability of being an apex predator, and you would not expect to see apex predator species flourish UNLESS they were well adapted to subsist on a mainly-vegetable diet.

Alternatively, you would see predation on other, more distantly classes of animal (e.g. mammals preying on fish or insects), because those other classes of animal would not have the toxicity adaptation and would therefore be edible.

Or predators would form symbiotic relationships with the microbes that can break down the prey's toxins and predators in different regions would have different microorganisms living in them to deal with the mix of prey in a specific area.

I'm sure there are more possible solutions. Biology gets inventive sometimes.
Yes, but on the other hand, evolution tends to work incrementally. Some niches just don't get filled, if filling them would require multiple unrelated adaptations to evolve in the same species at the same time.

I'm not proposing an explanation that says GUARANTEED NO LARGE CARNIVORES EVER. I'm proposing an explanation that says "large, primarily carnivorous animals, occupying niches comparable to the apex predators of Earth, would be statistically less likely to emerge here."
 
So-so. In principle it could work, but that kind of biochemical defense is fairly easy to circumvent, evolutionarily speaking; Compare antibiotics, and how the more you use them, the more you get pathogens that have developed immunity to them. On the scale you're talking about, predators would adapt pretty damn fast, and the poison would almost have to have developed before complex animals did in order to be spread across all animals. Barring targeted outside intervention, of course.
I'm proposing a situation in which one specific class of animal on the Shanpurr homeworld, the one which through historical happenstance is the dominant species of land animal (analogous to mammals on Earth), has this adaptation. And different species would have different toxins or blends of same, precisely because they are in a constant evolutionary arms race with various kinds of parasites or pathogens. And this is a barrier, not an insurmountable barrier but nevertheless a barrier, for a hypothetical species in this class that evolves towards "carnivore" status of subsisting mainly on the flesh of other animals in that class.

So basically, if you are a [mammal-equivalent] on their planet, adapting to eat members of a new species presents some obstacles, and adapting to eat the flesh of large land animals in general presents considerable obstacles. This is in addition to any adaptations required in order to catch and kill members of those species in the first place, and to digest their meat.

Thus, evolution is slower to fill the "apex land predator" niches on this planet. Surviving in such a niche is more precarious*. And the species that do function in that niche are more likely to be "multirole" species that can also function reasonably well on a primarily plant-based diet.

I actually have a theory about that. You know how in quest star trek the original generation is a mix of exaggerations, and excessive visual shorthand? well enterprise was an inquest docudrama production, and dear doctor got them sued by the estate of just about everyone involved who had one. The actual situation on the ground was likely greatly oversimplified, with lots of important facts left out.
In my "2235 quest" idea, the basic approach would be to slam the reset button very hard, and justify it with aftermath from the Temporal Cold War (that is, altering the timeline starting in the 2230s can loop back and retroactively alter events that took place at an earlier point in time).

My answer to all Enterprise-related questions would boil down to:

"Imagine that the series was created, and hit all the same story arcs, with most of the broad plot outlines being similar, but instead of it all being kinda crappy, imagine it was really really good. Yeah, that is what happened."

Actually, you forget another major constraint.

Toxins and toxin resistance are expensive investments, especially as the evolutionary arms race continues. Because of this, you generally see toxins (especially toxins in prey species) evolve in relatively stable environments. Because if the environment is not stable, having to spend, say, 1% of your food intake on producing a toxin is a bad investment if you need that 1% to not starve to dead. This is why generally speaking you see the most powerful poisons in species in warm environs and fewer species with weaker poisons in colder environs.

This equation changes again when the poison is a metabolic waste product, but in that case we're talking about a waste product, and the species producing it may be more tolerant of the poison, it will kill them eventually because it will eventually prohibit further metabolic activity. Either that, or something develops a way to metabolize the waste product and lives off it.
 
This is true, but it's also a fully general objection that can be raised to any conceivable species or class of species evolving to have any conceivable adaptation.

Obviously, EVERYTHING involving biology and metabolism is a complicated multi-factor combination of different things. And every possible evolutionary adaptation is the result of SOME tradeoff point among all these multivariable factors- accepting more intelligence at the cost of more traumatic and risky births, accepting more resistance to some environmental factor at the cost of being maladapted to another environment, accepting toxins that kill noxious parasites dead dead dead at the cost of needing to eat more calories to survive, and so on.

What I'm getting at is that we can plausibly imagine alternate ecosystems, biochemistries, et cetera, such that these tradeoffs are made differently. Where different "price points" on the various sliding scales of tradeoffs are optimal. And that this can in principle have significant consequences. Consequences like "it's a lot harder to be an apex predator on this planet" or "it's a lot easier to be an apex predator on that planet."

And I'm proposing the 'toxicity' thing as one mechanism that might push a given planetary ecology, or at least the parts of it where intelligent life might notionally emerge, towards the "harder to be an apex predator here" end of the spectrum.

I think that's close to the same solition that I've shrugged my way to with regards to Enterprise.

Uh, what? Who was sniping? Not being sarcastic here, legit question.

I also got the impression you got more toxic species relatively speaking as well. However, I was implying that warm environs are more long term stable than cold environs.

Again, not necessarily. Droughts, wildfires, or the complex and interdependent ecosystem of rainforests, do not for a more stable environment make than unusually cold winters, I don't think.
 
I also got the impression you got more toxic species relatively speaking as well. However, I was implying that warm environs are more long term stable than cold environs.
Looping back to your original point, in colder climates, disease and parasitism and predation are relatively lesser threats, while cold and resource scarcity are proportionately greater threats.

Thus, an adaptation that defends against other organisms at the cost of resources isn't very valuable to creatures that live in the arctic. Unless of course it's a low-cost variation on some adaptation that would be needed anyway (i.e. you need fur anyway, so it might as well be colored for camouflage).

And I'm proposing the 'toxicity' thing as one mechanism that might push a given planetary ecology, or at least the parts of it where intelligent life might notionally emerge, towards the "harder to be an apex predator here" end of the spectrum.

OK.

To start with, all alternate ecosystems must work with the same laws of physics. Energy is energy. Entropy is entropy. And every organism will try to get away with as much as possible.

And animals that are walking around are really concentrated sources of nutrition. If an organism can eat them, that organism gets a big leg up. No need to sit there photosynthesizing, or chemosynthesizing, or filter feeding, or spending hours grazing... Against that, there are downsides to being a predator. Like risks of injury from fighting with prey. Like the risk that you'll starve from all your prey will run away. And there aren't room for too many creatures like you. (There may be billions of blades of grass, millions of insects living on that grass, hundreds of thousands of large herbivores but only thousands of predators in an area.) But generally, it's a pretty good strategy to eat meat.

So if you have a situation where the prey are deploying lots of toxins... Well, of course that makes things harder on the predators. But it is still a great strategy. So less organisms might be predators, but there'd still be plenty of predators.

Especially since the prey are diverting energy from being fast, from being strong, from breeding faster, from being more social, from being able to eat themselves, and using it to make poison. So the prey are weaker in some other area to compensate for being better at poison.

The weakness of they prey and the necessity to adapt to eating very specific prey would, I would think, encourage the evolution of smaller and more social predators or of predators with very large ranges so they could get more out of the prey in their range.

I would think that flocks of predatory birds would be especially successful, since they could have very large ranges and their small size wouldn't be as much of a disadvantage as it is on Earth since predators would want to be small in any case, so that they could maintain useful breeding populations on the available population of prey.



Now, if you have a situation where rapid environmental change has disrupted the close relationships between evolved predators and prey, meaning the predators haven't been able to get enough food to maintain a viable population, well, that means there is a big fat opportunity for a new predator to evolve to fill that niche.

As an example, when we look back in the fossil record to see what happened after the great impact that killed the dinosaurs, ecosystems seem to have been heavily disrupted for a few hundred thousand years. But remarkably quickly, the ecological niches were filled up. After around 5 million years (an evolutionary blink of an eye) the diversity of land-based life had reached about the same level as before the impact.

If you have a situation where there are factors making things changing too fast for predators to emerge as a major part of the ecosystem, then selective pressure for prey species to maintain their toxin levels will fall, meaning that more fit but less toxic prey species will evolve and out-compete the slow, weak, less fertile, less sociable prey species and then provide opportunities for unspecialised predators.

Also, I would like to say that an ecosystem with rapid change and lots of toxic animals that required very specific strategies to detoxify and eat sounds like a great environment to encourage the evolution of intelligent predators.

The rapid change means there's not much competition from other predators but there is a big fat opportunity that makes a big expensive brain something that can pay off.

Sounds like a situation that should have encouraged predatory Shanpurr.



Also, what you are speaking about "apex predators", here's the actual quote from the omake by AKuz:

Shan is one of two known biospheres to produce intelligent life that posses a very limited degree of predation and aggression in flora and fauna. Most species, including the Shanpurr themselves, are Herbivorous.

Yes, it is easier to imagine an ecology that lacks apex predators like lions or tyrannosaurs. And maybe, as you say, the casual survey didn't notice the small predators, but the choice of words "very limited degree of predation and aggression" seems to imply more to me.

And it is less easy to imagine an ecology without foxes, jackals and falcons.



Nnnnot necessarily true. As my prof put it, the main reason you get more poisonous species in warm climates is that you get more species in warm climates, period.

Hm. I can't think of anything really toxic from outside the more fertile ecosystems on earth. The most toxic things I can think of all live in rainforests or coral reefs.

Okay, I'm going to be perfectly honest, I'm giving up on this conversation. I'm not in any way disputing your intelligence, your expertise, or your correctness.

But... before I stop, I would like to make a point about why I think this kind of approach can become counterproductive.

Something I said a long time ago on another forum, that got 'promoted' to Atomic Rocket...

Respecting Science - Atomic Rockets

I said:
I suspect that most of these wannabe writers are getting their first introduction to 'putting the science in science fiction' in the format "you can't do that." You can't have a planet-city because of heat pollution, you can't have an FTL communication system because it creates causality loops, and so on.

It's pretty depressing when every cool idea you ever have is getting shot full of holes, especially by someone who talks down to you. At some point, the natural reaction is to say "F--- it, I'm never going to get anything done if I keep listening to this guy drone on about all the things I can't do!"

Science and fiction aren't the only place where this happens. People can only juggle a limited number of important points in their head at a time; if you pile enough rules and confounding variables on them they start rejecting some of them simply as a defense mechanism.

So I think a lot of them are rejecting science because of a marketing failure; science is presented to them as a list of things they can't do. And the list is so long that they can't possibly remember all the rules, which makes it even more off-putting.

Talk to people about what they can do, or suggest what they should do, and they'll be less inclined to rebel against your advice than if you tell them they're wrong and dumb.

Most people prefer to be left with some ideas that are at least as interesting as the ideas that get shot down by the power of SCIENCE!, because otherwise they come away from the exchange of ideas poorer rather than richer.
I would like to humbly suggest that if you want people to listen to you about crafting biologically plausible alien ecosystems, you start by taking a premise like "imagine a world where predation is minimal and an intelligent species emerges that is super-social and very nonviolent" and helping them achieve it, or slightly redirecting their ambitions so that they achieve the relevant aim without stomping over as many scientific laws.

If you start with the opposite approach, and you pursue it vigorously enough... You are ensuring that people will have very little incentive to consult a biologist before telling a good story.

Because if you do things the former way, they come to you with an interesting story, and they leave with a scientifically (less im)plausible interesting story.

If you do things the latter way, they come to you with an interesting story, and they leave without one.

True.

I reject these premises and feel no more required to abide by them than a television scriptwirter with 18 hours to break a new episode.

Your move.

I sincerely wish you all the best in finding the audience who want to read the stories you want to tell.

I would like everyone to know that all of my OC species and worlds were completely hard science based and perfectly plausible.

Especially those fuzzy green muppets from Lamarck.

You've done well in avoiding explaining things that don't need to be explained.

It's not like we need an explanation of why the fuzzy green muppets are fuzzy green muppets for most stories we'd want to tell about them.

Snakes, spiders and scorpions come to mind..

I seem to remember that the ones in more northerly climates are less toxic than ones is warmer and richer climates.

Of course, I may be wrong. For one thing, on Earth, the cooler climates tend to be more disrupted by human intervention. Also, the changes the climate fluctuations of the ice age had a bigger impact in the cooler ecoregions.
