I've been following this field closely for the last 5 years, its really cool what we can learn about our own ancestry now!

For those interested in a good overview David Reich's book is still excellent - https://en.wikipedia.org/wiki/Who_We_Are_and_How_We_Got_Here

And if you're interested in an in-depth ancestry analysis of your dna you can use commercial options like https://illustrativedna.com/ or analyse your dna yourself with qpadm https://uqrmaie1.github.io/admixtools/articles/qpadm.html

For people interested in publicly traded companies (this is not investment advice and I am not qualified whatsoever) that make this possible: NASDAQ:PACB and LSE:ONT.

To the best of my knowledge, ILMN and other similar short-read sequencing technologies are not able to perform to the level required for these sorts of applications.
