epigenetic triggers

Rachel, "But furthermore, is this "something" deciding to create things?"

Most literally, "something" is turning on, or off, inheritance. This something is the immediate environment. From memory, a gene can be turned on in the next generation, when the previous generation has experienced e.g. famin. Pembry found that famin experienced by the parents can turn on a stress hormone in the children. Or the eating habits of the grandparent can determine the life-expectancy of the grandchildren. This is called the 'transgenerative response' in epigenetics. (That is, genetics immediately influenced by the environment.)
