Abstract

Micro-evolution in declining populations can be defined as the result of the interaction between natural selection and genetic drift, where the latter increases in importance the smaller a population becomes. The purpose of this project is to examine this interaction by using the woolly mammoth as a model system for studying real-time evolutionary changes in declining populations. I will generate complete genome sequences from up to 100 woolly mammoth specimens spanning the last 25,000 years of the species’ existence. This time period encompasses the dramatic changes in climate at the end of the Pleistocene (15-11 kya) as well as the subsequent isolation of mammoths on Wrangel Island, where a very small population survived for 6,000 years until the species became extinct.
