Human evolution and migration makes perfect sense.
Why do Aleut and Native Americans resemble Asians? Because their ancestor migrated over the land bridge from Asia. By looking at changes in the DNA sequences of certain genes, one can determine when ancestors of people in certain regions settled in the area. An example- the Basques are not from France or Spain, but elsewhere.
Why are certain blood types more prevalent in certain areas of the globe? Human migration and the founder effect.
Sorry to burst your bubble, but people are animals too. Of course we see that every day.
