Whether it is in the Genes, or the body cells, memory must be able to be inherited.
How else do you explain a birds ability to build a nest, or the bee's capability of maintaining a complex hive.
In an experiment, two groups of monkeys were threatened by a plastic snake. The group bred from monkeys exposed to snakes in the wild were terrified. While the group bred from monkeys that had no contact with snakes in the wild ignored the snake.
By the way, If you think that building a nest is so simple that a bird-brain can do it, try it some time.
We were given the task to try making one when I was at school. Even with our vastly superior brains and our opposing thumbs, the birds still beat us.
