Based on my own klnowledge of molecular genetics, it is not an easy thing to determine it was of a certain age.Kim van der Linde Robert , 21 June 2006 (UTC) I would suspect that "big changes in tortoise DNA" involve a population bottleneck (due to the cull).I believe the protein racemization methods are the best that have been developed to date for that type of research.

That is not something that DNA testing can be used to do without a huge amount of work involving the rates of mutation within a species, knowledge of diet, personal radiation exposure history (i.e.what altitude the individual lived at over the course of their lifetime; exposure to rocks producing significant amounts of radon, etc.).Question: does anyone know how an organism's age can be determined from its DNA?--Anshelm '77 , 24 June 2006 (UTC)Meanwhilst, this article linked to from Australia Zoo claims her to have been born in November 1830 making her 175 (I have corrected the article, we may as well go with the owner's claim).If you would like to participate, you can choose to edit this article, or visit the project page for more information.
This article is within the scope of Wiki Project Zoo, a collaborative effort to improve the coverage of topics related to zoos, aquaria, and aviaries on Wikipedia.however, one has to wonder that if the Darwin connection doesn't hold water, how well autheticated her age can really be?I do remember her from the news in 1997, though, when it was reported that based on DNA testing she was 167 years old.This article is within the scope of Wiki Project Biography, a collaborative effort to create, develop and organize Wikipedia's articles about people.All interested editors are invited to join the project and contribute to the discussion.Jian Li , 28 March 2006 (UTC) I have seached the scientific literaure, and beyond the claim i the popular press, there is no information available.
