Reconstructing the genetic composition of the Grey wolf (Canis lupus) populations across Europe from the Neolithic period to 20th century.
Grey Wolves (Canis lupus) have been subject to extreme bottleneck’s since the last glacial maximum in response to evolutionary, ecological, and anthropogenic pressures. The consequences that are typically theorised to be exhibited from this is that the species will have reduced genetic diversity acr...

Grey Wolves (Canis lupus) have been subject to extreme bottleneck’s since the last glacial maximum in response to evolutionary, ecological, and anthropogenic pressures.

This study will reconstruct the genetic composition of ancient and modern samples using a comparative investigation as well as DNA extraction. Sanger sequencing of mitochondrial DNA will provide the genetic diversity of the modern and ancient samples collected in this study.
