Usually, we assume that higher genetic diversity in a place means more time, more branches of the ethnicity in question.
But take a look at this.
In Spain, the DF27 branch is 40% of all R1b haplogroups (70%). More than half of a single most common branch. 2 Google searches prove that.
While in Mexico is like only 8% is DF27 out of a 40% prevalence of R1b. 20% of the single most common branch.

And nobody will think that the European haplogroup came to Spain from Mexico.
We more than know it came TO MEXICO during colonial times.
