I rather think that the switching of self awareness and of personal value is not like a light switch. I don't think that one generation of early humans got a sense of personal value and the one before didn't. Although it would be impossible to know to what degree of self-awareness animals or even other humans have. I'd imagine that early man had a degree of self awareness. We don't know and in fact as individuals even cannot know how self aware others are.
I also think that the connection between point 4 is tenuous at best. Rather like three debatable points and then a statement that has thin connection to the other ones.
