In SNW 1x09 All Those Who Wander, the crew reenact Aliens with a handful of baby Gorn as their adversaries. We learn that Gorn breed by infecting a host animal with eggs, which hatch and burst out of the host when mature (which can take months or hours, apparently depending on the host). The babies are immediately hostile to other baby Gorn, and are left to their own devices until they are picked up by adults at some indeterminate point. We also learn that these baby Gorn are themselves capable of implanting eggs in a host by spitting on them.
These baby Gorn seem like a full fledged viable species already: small, vicious hunters who are (like tribbles) basically born pregnant. From an evolutionary perspective, that’s plenty to propagate their own existence. It’s also a lifestyle that selects for intelligence (small hunters tend to be pretty smart) but seems like an unlikely route to developing genuine sapience. We’d expect these baby Gorn to have a relatively stable population given the turnaround times of egg maturation and their predilection towards cannibalism, and the later feature would also make it far less likely that any given individual would survive long enough to become an adult, as each fresh generation brings a wave of fresh adversaries who vastly outnumber the handful of survivors from previous waves.
Of course, we know there are adult Gorn. So, how did they come to be? Why would there be a species where the adults are intelligent and social enough to be a spacefaring power, and yet apparently nothing they learn as an adult is needed for an individual to pass on it’s genes?
I tried to touch on this in my OP, but the problem with this is that unless Gorn generations are very spread out (unlikely, given the rapid gestation period and rather ad-hoc method of implanting eggs), the odds of a “superior” elder beating out all of it’s slightly younger competition remains quite slim. This is a brawl, not a neatly organized bracket, and random chance will invariably play a big role in who wins and who loses. The top Gorn from generation A suddenly finds itself as merely a slightly advantaged individual in a whole new field of competitors the overwhelming likelihood is that one of them will prove the ultimate winner, and then suffer the same fate. If the “strongest M&M” were thrown into a fresh bracket instead of being mailed to the parent company, it’s almost certain to be toppled. You wind up with a species whose “true” lifespan and adult form is irrelevant, because every individual dies long before they come anywhere near adulthood.
More importantly from an evolutionary perspective, though, the success or lack thereof of an individual Gorn has almost no effect on their ability to reproduce. All the Gorn need, apparently, is to survive long enough to spit on a viable host. Anything that happens after they do that is irrelevant, and thus won’t be selected for evolutionarily. And it strikes me as highly improbable that growing to much greater size and having enormous strength (never mind developing sapience) are unlikely to emerge by pure chance without evolutionary pressures making those traits more likely to be passed on.
The “Strongest M&M” problem is probably mitigated by lower density of baby Gorn in the wild than what we’ve seen on screen so far. If a brood typically manages to winnow itself down to a single individual before any of them can spit on a host, and the hist typically has enough time to travel somewhere else before the next generation hatches, then you have a situation where the strongest of the babies will generally reproduce and then generally have the chance to continue growing into “true” adulthood. Unfortunately that still doesn’t answer my second question of how that adult form evolved at all when it’s very existence has no clear benefit to the animal’s ability to reproduce.
This uncontrolled breed-mayhem on that planet may be, because it was this situation out of the norm. From what La’an said, i had the impression that they systematically used the humans for breeding and food.
The Young ones could be left to their own devices in a controlled manner. Much like birds, the younglings of some species also attack each other. The strongest survives.
I like to think that, at home, the adult Gorn pretty much have their kids under control.
But, yeah, they reproduce out of the box.
It’s because, aliens …
