DNA, how it is passed on, and what is being learned about what affects it, is beyond human comprehension. One interesting aspect is that extreme events do change ones DNA. Does that mean that people really can remember past lives, through their DNA? Does that mean that it just might be that you might meet someone who you're immediately attracted to because of a past-life experience? Do tribal cultures truly have shared cultural memories through shared DNA?
What is being learned is mind-boggling. I wish I had the capacity to better understand it all.
A Red Heeler pup is born with an ability to identify a sick or abnormal sheep or steer. They can calculate exact time and distance results long before executing the variables. There are things in their DNA which are in no way learned or taught. They just got handed down and constructed in the brain or soul from prior generations during development in utero.
