Discovery News OR How DOES Google Know?

 I’ve been reading Native American history lately, and I have a draft of a blog post about the American West waiting for a little more work.  So, I eagerly clicked on the link in my gmail this morning that took me to this Discovery Channel article about new archaeological discoveries related to Native Americans.  It seems that, based on mitochondrial DNA, they can be traced to six founding mothers.  The article itself is worth a look, especially for educators, since at the bottom of the first page there is a nice video about the “cool” job of archaeology.

Here’s my question on this early Sunday morning: how did Google know?  Or, was it just a coincidence?  I’m used to the links at the top of the page being related to my email.  In fact, it’s even funny sometimes how they find just the right link to go with whatever I’m reading.  But, as far as I know, I haven’t either sent or received email related to Native Americans.  I have, however, done several Google searches so perhaps that’s where it’s coming from.  Or, maybe, it is just a coincidence.  And, while it worries me a little that Google seems to know a lot about me, I’m also sort of happy since I probably wouldn’t have found the article on my own.
