Without realizing it, humans might be able to innately detect Earth’s magnetic field, thanks to a compound found in our eyes. Or we may have been able to do so some time in the past.
Neuroscientists at the University of Massachusetts took a human version of cryptochrome 2, and inserted it into fruit flies that lacked their own version. The fruit flies’ magnetic perception was restored, as Wired Science reports.

Humans are migratory, and have been for hundreds of thousands of years.

No they are not, their prey may be, so sometimes they follow the migrationary paths of other animals. Humans though are territorial. When anthropologists talk of 'human migrations' they mean mass movements. Those mass movements, we are finding, are usually precipitated by changes in their usual and preferred environment which led to scarcity of food. Which is, presumably, why we developed tracking abilities, so we could find where the animals were going on those occasions when they didn't return due to those environmental changes.

You clearly have never been to Vancouver and Sydney Australia. Humans are migratory and go where the resources are just like animals.

This is just like the "toe" bones that show up in whale fins, vestiges of something from the distant past that have no use or relevance for humans in the current era. Humans learned to figure out where they were from looking at the Sun or the stars a long, long time ago, and have been doing that very same thing ever since. It's kind of interesting, and maybe we use it at some subconcious level, that we can't fathom right now, but, interesting none the less. Now, if it some thing that is NOT old, but something that is just starting to occur, that could have some pretty interesting implications! (Precursory evolutionary reaction to a potential pole shift maybe?)
