Many mammals and species around the world have giant ancestors. From Megalodon to Titanoboa, sharks and snakes had ancestors that were double or triple their size... so then couldn't the same be true for humans? This week on The What If? Podcast, we explore that exact possibility—that we have preceding humanoid ancestors that are, well... BIG.

From burial mounds in the midwest, to Giant Gingers in the Southwest, to mythical giant beings of history, this week we wonder whether or not we were one day big. We didn't even make one joke about the movie "Big." And Ryan's even seen that one. What a missed opportunity.
