** Bottleneck is a good word. During intervals (particularly the interval preceding the ninth threadfall) the numbers of Queen dragons decrease and the genetic diversity probably drops sharply. There are also few culling mechanisms for Dragons short of bad between transfers, duels and injuries in the training games. On the approach to a Pass, though, the dragons start mating with increased fervor, clutch sizes rise and the weyrs increase the number of queens. It was also the tradition that weyrs allowed open flights, bringing in fresh bronze blood. This would increase genetic diversity and health and, of course, fighting thread provides an excellent culling mechanism. There have also been some dragon plagues mentioned, which would provide an alternate method of purging draconic bloodlines of less healthy examples.

Nobody is particularly surprised to see Ruth's egg - they aren't shocked at Ruth after he hatches either, they just feel that he is unlikely to survive, and a small egg is seen as being unworthy of impression. It's clear that hybrids have occurred in the past.

** Her trip wasn't that long. A human can survive vacuum exposure without long-term side effects for up to 90 seconds. Lessa, upon her arrival in the Oldtimers' era, is said to be more dead than alive, but shows no evidence of long-term damage such as hearing loss or damaged vision. So the duration of her trip was only about a minute to a minute and a half, though even that was enough to leave both her and Ramoth in terrible condition.

* So it's been established that, under normal circumstances, the time a dragon spends ''Between'' is about three(3) seconds. In ''Dragonflight'', Lessa says it took about twice that long to travel ten(10) years through time. Assuming that pattern holds true, then by my math (450 ÷ 10 = 45, 45 x 6 = 270, 270 ÷ 60 = 4.5) she was in a vacuum for nearly five(5) minutes when she went back 450 years to get the Oldtimers. Given that brain cells begin to die after only one(1) minute without oxygen, how did she survive the trip without incurring serious brain damage?

*** Not judging by ''Dragonflight'' itself -- when Ramoth rises and Mnementh catches her, F'lar takes Lessa in his arms and explains that "We bring them safely home".

** IIRC, the 'good maternal instincts' at the firelizard level mostly meant that the golden mothers were willing to protect the nest until the eggs hatched and the babies impressed, whereas the greens would lay eggs and forget they existed. In both the lizards and the dragons, once they're Impressed, they appear to be treated like any other member of the group. Ramoth does care about people messing with her eggs!

*** Indeed, dragons (and fire-lizards) might be expected to invest less maternal devotion in individual offspring, given that a large fraction of their young (blues, firestone-chewing greens) are effectively genetic dead ends. The smaller colors of dragon are more like soldier ants than anything - they have value as colony defenders, but not breeders - so naturally receive less parental concern. Even gold and bronze offspring are as much competitors as heirs, considering how quickly their young become breeders relative to their parents' lifespan; a queen dragon that gets too sentimental about her daughters may find herself ousted from her dominant role by one of them. So it makes sense that Ramoth wouldn't think of her offspring as her sons and daughters; in calling Amaranth a "true daughter", she was probably borrowing a ''human'' term to express her (non-maternal, just admiring) appreciation for Amaranth's good qualities.



** Wrong, familial ties are actually quite common amongst the animal kingdom. It's just that dragons have pretty little of this in them.

*** It depends on the animal. Given that the initial population of engineered dragons was so tiny, it's possible and even likely that any incest-aversion instincts would have been suppressed in them: either deliberately by the scientists who created them, or via natural selection during the first few generations. Male dragons that ''wouldn't'' rise to mate with related females simply didn't leave any descendants, and females that rose only reluctantly when only male relatives were available didn't fly so high and laid fewer eggs.

** It was an expression of his determination to do everything he could to win the mating flight. His dragon used some kind of trick (doubling back somehow? I just remember there was a trick, his dragon turned up somewhere hers didn't expect him & caught her) and when he said the above quote, Torene realized he had planned this with his dragon because he wanted her so much. That doesn't mean it makes sense for him to talk like it was all up to him, but McCaffrey can be a little into the "dominant, pushy male = hot" thing, as demonstrated in many scenes.

to:

\n** Not to mention the fact that existing more than once at the same time is very draining and disorienting. "I am too many today." Lessa fainted when there were only three of her, and these riders and dragons had to double back on themselves many more times than that to get everything deliverred at once. They likely wouldn't have been ''able'' to rest effectively in such circumstances.
