The Scientist just posted an article in which a genetic tree approach is used to study the spread of viruses – in particular the novel Coronavirus. I think this is interesting because I think the method is similar to that used in the Hundley study – perhaps it is a bit more understandable because the amount of data is so much smaller bute we are still observing worldwide spread. https://www.the-scientist.com/news-opinion/coronaviruss-genetics-reveal-its-global-travels-67183?utm_campaign=TS_DAILY NEWSLETTER_2020&utm_source=hs_email&utm_medium=email&utm_content=83909011&_hsenc=p2ANqtz-91i_2aYYeoRZV2hnphH-XJdOh05rnxR82z3jpwcSQVdhG-yYxqxjJypJOs_cKG0xnm7xIB9mMF_LMcpunL-jckjxC1Wg&_hsmi=83909011

Here is an article on 6000 years of genetic history in Sardinia. Interesting because it can be tied to the historical and archeological record. Evidence for isolation followed by several different experiences of admixture. I am curious how this data would fare in a Hundly stye tree.

Some thoughts on what we need for an analysis of the Hunley and Cabana paper

We need definitions:
Serial Founder Effect
Admixture
Localized gene flow

Tree-building
How is this done?
What is a “global population tree”? How is it constructed?

What is “gene diversity”? How is it measured?

How are the tests of the trees conducted?
