What’s amazing is that Monarch Butterflies can return year after year to the same wintering grounds. But NO butterfly lives long enough to make the entire round-trip from summer home to winter home and back to summer home. It truly is embedded DNA memory in those itty-bitty butterfly brains.

Maybe it IS true she has a “embedded DNA memory.”

Funny you should say that. When I was in college, I did a study abroad in Bohemia in the Czech Republic. It was just an opportunity and I took it... I had no previous knowledge of the area and no deep desire to go to that specific place. We traveled all over South Bohemia, drinking in all the little medieval towns and visiting castles. I loved it.

Twenty-five years later, I was researching my grandmother's genealogy. She was adopted and we knew nothing about her biologicals. We submitted my uncle's DNA and found matches. Turns out my grandmother's grandfather was from the town of Brno, and that summer I had been drinking beer in a tavern about a 15 minute walk from his church parish.
