Welcome to Episode 5 of Slightly Evolved! Our guest is Patrícia Pečnerová a PhD student at Stockholm University and the Swedish Museum of Natural History.This week we are talking about what the extinction of the mammoth can tell us about current conservation. We talk about how you get DNA from a 4000 year old mammoth and what genetic changes were seen in populations before they went extinct. We also talk about her work as a contributor for the molecular ecologist blog, and how writing posts on different subjects can also be a great learning experience. In the episode we mention the book "How to clone a mammoth: the science of de-extinction" by Beth Shapiro which you can find here (https://www.amazon.co.uk/How-Clone-Mammoth-Science-Extinction/dp/0691173117/ref=sr_1_1?ie=UTF8&qid=1488115539&sr=8-1&keywords=how+to+clone+a+mammoth) and the molecular ecologist blog, which you can find here (http://www.molecularecologist.com/). Both are highly recommended reading!As always you can contact us via email ([email protected]), Twitter (twitter.com/slightlyevolpod) or join on our Facebook group.
