Hi there. I want to ask you if you have some stratigraphical control or absolute dating on those mammoths. This is because I think that the hypothesis of extinction due to this abnormalities is not sustained by evidence (I could be wrong of course). Also, did you perform any ancient DNA test to prove the inbreed you're talking on the paper? Thanks for your time.

Why would you include in your sample the bones that prompted you to ask the question? You need to exclude the 3 mammoth bones from the Rotterdam museum. At best your sample size is 1 anomalous vertebra in 6, rather than 3 in 9. Although it's hard to even know what to make of your 'sample' when you include some vertebrae 6 and some vertebrae 7. Aren't there mammoth bones in museums all over nor...

When reading in on this article, I wondered to myself that if the mammoths had a declining population could they be subject to higher rates of genetic deformities? Is there a correlation between these factors? Either way it's an interesting find...
