When reviewing my DNA test results from 23andMe, the "Neanderthal Ancestry" section states "We've identified 272 genetic variants that can be traced to the Neanderthals, ancient humans who interbred with modern humans before going extinct 40,000 years ago - this is less than 54% of 23andMe customers and your DNA accounts for less than 4% of your overall DNA". So, I immediately furrowed my (Neanderthal) brow, joined the 23andMe discussion forum and searched for more answers on what this DNA result actually meant. Upon reading my DNA results and the related White Paper 23-05 "Neanderthal Ancestry Inference", some of the discussions on the topic, and further research on the Wikipedia.org: Neanderthal page, I found a wealth of information.
