Doesn't that mean it's not actually extinction, but more like domestication?
> By the time that day comes, however, the wild axolotl may be gone. That worries Gardiner and Sandoval Guzmán because the animals that they study, like many lab animals, are highly inbred. Scientists use an ‘inbreeding coefficient’ to measure how small a gene pool is. Identical twins have a coefficient of 100%; totally unrelated individuals would score close to zero. A score above 12% indicates a population in which individuals are mostly breeding with their first cousins, and is considered a serious concern by ecologists and geneticists. The famously inbred and unhealthy Spanish Habsburg kings of the seventeenth century often had a coefficient somewhere above 20%. The average axolotl inbreeding coefficient is 35%.
You may be interested in learning more about genetic drift and effective population size, it should clear things up:
Also if they are so prolifically inbred in captivity, couldn't they capture another specimen and start a new line either with a captive specimen or another wild specimen?
As for answers: answers to what? Topsoil loss (about 50 harvests left and counting)? Freshwater disappearance? Billions of sea-level-rise refugees with the inevitable resulting regional wars?
Unlimited so-called 'economic growth' has always been imaginary (it's not 'growth' in anything; it's entropy transfer as we shift from from complex and sustainable systems evolved over millennia to crude early-stage technological systems). It is not so glorious a work of the imagination it is worth destroying our real physical living home for.
Evolution Darwin already knew (and even more so we nowadays know) is a complex mechanism, that includes favoritism of certain traits of species over others, which steers a species' fitness for the environment, and several factors play various roles, e.g. epi-genetics.
All of us dead.
Their only natural habitat is city canals?
No idea how long the eggs can aestivate. Nice genetics/biocaching crossover there.
I hoped to see a nationload (MX, BR, something) of LEED living roof that included or adjoined estuary, I guess we know the jaguar (ocelot...) is less a hazard. It just has to be nicer to keep occupied canopy over most of the estuary (so birds don't run off with the cache in minutes) than it is to run ventilation or spend marginal time (¨) on cash crops.

So Toothless was inspired by Stitch and, probably, cats.
