The author was wondering if she would be passing her parents' trauma to their grandson.

I watched an interesting documentary of the rabbit to bobcat ratio in the Yukon. For years, biologists have been tracking the prey/predator numbers. The population trends were not matching the current theories.

In most bobcat-to-rabbit encounters, the rabbits usually escape. But that escape triggers a stress response for the DNA.

When bobcat numbers are high, the rabbits get their epigenetic response turn on. It helps them be more wary of bobcats. It also reduces the average size of their litters from eight to three baby rabbits. So the food supply is not being replenished for the bobcats, who either starve or move away.

When the bobcats are gone, the progeny of that generation still breed with litters of three--even though they are not being hunted by bobcats.

The documentary said this study was still ongoing. The biologist were trying to figure how long the three-rabbits-per litter was going to stay on. What generation will the rabbits go back to litters of 8?

Quite fascinating. Too much stress is harmful to animals and humans, intergenerationally speaking.
