      5.) The only species we are likely to bring back are those which we consider 'interesting.' So the slug-like Macedonian newt, which squirts pus out of its eyes, probably isn't going to make it (made up species).

      I don't have a source for this, but I seem to remember, in the context of a discussion about Cheetah evolution, the figure of 50 breeding pairs being suggested. It seems cheetahs passed through a period when there were very few of them alive at the same time, a near extinction phase, so that all cheetahs alive today are descended from the same small cluster of breeding pairs. The gestimate there is that 50 is about the minimum that a mammalian species might rebound insead of going extinct, particularly from accumulating lethal recessive genes during the bottleneck phase (I think that's what you really mean where you mention 'genetic deterioration' due to inbreeding). That's a figure the molecular biologists were basing on a complex calculation, particularly limited to mammals on the basis of the evidence they had as of the year 2000 or so, but it sounds like it would apply pretty well to Mastadons or Mammoths, and big predatory marsupials or birds are likely to not be too far from that number either. I'm pretty sure we could get some DNA from 100 different mammoths, less sure if we could narrow that number down by knowing what the mammoth lethal recessives are and screening for them all, or knowing where modern elephant DNA strings could be used to repair damaged samples, or any of the other suggested ways to get a decent sized starting population.

      Is it even practical to bring back an extinct specie? I am wondering how many individuals with varied genetic code is required to avoid the issue of inbreeding.

      Lets say I found two perfect genetic samples: One male and one female. I placed them into my magical DNA-To-Fertile-Adult(tm) machine, so now have two organisms set to reproduce. But then we run into a problem: Even if those two have 30 offsprings any further mating will result in genetic deterioration due to inbreeding.

      So we need to have quite a bit more samples. What is a minimum population count that we need to hit in order to avoid this? Could we possibly have that many different samples of an extinct organism to fulfil such a quota?

      Actually, it wouldn't be genetic deterioration. The problem with inbreeding is that the same defective genes are being expressed over and over again as dominant traits. If those traits are before/lethal within the breeding phase, then eventually the population goes extinct.

      So actually, you want "deterioration" - mutation. Because then the resulting diversity raises the odds of long-term viability.

    The DNA sequence alone is not enough to recreate the extinct species. Even if we recover the DNA perfectly. The embryo development is a complex process. Unless you have a surrogate uterus at the right temperature that douses the embryo with the right chemicals at the right time, it would not develop normally.

    Chinese River Dolphin

    #1, it happened in my life time. It makes it more personal. It feels like someone could have heard a story about the dwindling dolphins around 10 years ago, traveled to China, and done something about it. This really is the case where ONE MOTIVATED PERSON could have saved an entire species. It could have been me. It could have been someone reading this words. WE fucked up.

    #2, these were intelligent, attractive, sensitive creatures. It's like killing your dog, or making dogs extinct.

    #2, China was not a basket case country ten years ago. Modern, rich, growing, proud. It could reasonably have been expected some Chinese somewhere would have cared enough to at the very least preserve a tissue sample, if not a breeding stock. We're talking about something that the Chinese for thousands of years marveled at, lived with, considered kindred water spirits, perhaps even worshipped. These dolphins feature in ancient Chinese artwork, something their ancestors gazed on and felt kinship with. It's an insult on your ancestors. China: you built a dam, ran some river traffic, polluted some more without thought, and poof: a piece of Chinese identity, a Chinese national treasure, something a part of the fabric of your ancient nation: gone forever. Out of neglect. The slightest atom of national attention and interest and resources would have saved the Baiji.

    There's a lot of bullshit nationalist chest thumping in the world, but really CHina: shame on you for this, shame on you. You fucked up. Fix it.

    How? I don't know, start with a Indian River Dolphin as a template and engineer. Find some tissue in some bones in the muck somewhere. Bring the Baiji back. You owe your nation this, you owe your ancestors this, you owe the world this.

    China, you fucked up. The insult is to your own nation and your own ancestors the greatest. And you have shamed and embarrassed yourself in the world.

    Fix it.

    Check out straightdope.com. I can't recall specifically about Inuits, since a lot of mammoths are in Siberia, but not only local inhabitants have sampled mammoth. Some mammoths were discovered when people's dogs were found eating the odd trunk or limb sticking out of the landscape. And, if you're really obsessed with the idea, occasionally even non-native people have dined on mammoth. Just bring your checkbook.

    Not surprising, really. We have plenty of archaeological sites showing people hunt mammoths. Even today, some people hunt, kill, and eat elephant.
