When my youngest daughter Katie was little, I was driving her to Grandma and Grandpa Baugh’s house and I mentioned that it was Grandpa’s birthday. She asked how old he was and I replied, “Oh,he’s older than dirt.” “No, he’s not!,” she rather forcefully explained. “Yeah, he’s older than dirt,” to which Katie even more emphatically exclaimed, “No, he’s not! Grandma is!”
Turns out neither of them are older than dirt (although Grandpa Dennie is closer to it than Grandma), but what we can know about our DNA history does go back a ways.
