So I do a Google search on "mexican genetic makeup". I find a link to a site called worksheetsengine.com. It's got a little blurb from the site, etc.. Normal Google result link. So I click the link, and it takes me to what appears to be a Bing search results page for the same subject.
In fact, worksheetsengine.com by itself brings you to what looks like the Bing front page. It even has the little Bing browser icon.
But WhoIs says worksheetsengine.com is owned by Markus Culer, who lives in Saint-Petersburg, RU.
What's up with that ?

Perhaps it is somebody hoping to put tags/cookies on people who search for things via his browser, the better to monitor them and steal things from them. And they will be all unawares see, because they thought they just did a search on Bing.
(1. Give people cookies from my site. 2. … 3. Profit! illicitly)
