Natural Selection and Slavery

I have been reading the book about runaway slaves by John Hope Franklin and Loren Schweninger. It is an overwhelming book because it contains literally hundreds of stories of runaway slaves in nineteenth century America, with names and whatever scant details may be available from the historical record. The authors attempt some generalizations, but it is very clear that each slave’s story was individual and unique. And the documented brutalities are unspeakably painful.  I considered myself knowledgeable about American history, but this book took my breath away. No wonder the late John Hope Franklin is so famous among scholars and non-scholarly readers alike. This is the painting by Thomas Moran, who lived during this time, which is in the Philbrook Museum in Tulsa, where I live, and that was on the cover of the book.

And here is a photo of John Hope Franklin.

As a biologist specializing in writing and educating about evolution, I noticed a generalization that even the late great John Hope Franklin did not, and it has directly to do with evolution by means of natural selection.

Slaveowners and hunters believed passionately that slaves, and black people in general, were inferior in intelligence. Despite this, the racist whites of the South did their best to subject their slaves—and even free blacks, whom they sometimes kidnapped—to deprivations that were clearly intended to keep them physically and mentally inferior. In particular, they seldom allowed their slaves to learn to read and write (a literate slave could write out documentation that said they were free, for example), or to learn simple arithmetic, or to learn to read a map (which could help them to escape, if they should happen to get hold of a map).

Despite this, the runaway slaves proved themselves to be extremely intelligent and clever. As a matter of fact, the deprivations forced upon them by the whites selected for the most intelligent and clever slaves. The only way a slave could be successful was by outplaying their white overlords at their own game. One example that sticks in my mind is the slave who, on his escape route, asked a white train operator which train went to Raleigh. The slave knew that word would soon get around about his escape, and with his description. Asking the train operator how to get to Raleigh was a trick. The slave had no intention of going to Raleigh, but his question would mislead his pursuers into looking for him in that direction. Clever!

That is, the very ways in which whites oppressed slaves were in fact an evolutionary pressure leading to greater intelligence, over the generations, in the slave populations. Not only were black people equally intelligent to start with, but the evil efforts of the whites pushed black populations into even greater intelligence.

It doesn’t take any intelligence to be cruel or to be an oppressor. It takes intelligence to escape oppression. To this day, we are left with the image of stupid racists trying to belittle intelligent minorities.
