# II explained — Before Adam > Chapter companion for Before Adam by Jack London. ## What happens The narrator explains his theory of racial memory and the 'other-personality' that manifests in his dreams, arguing that he is a freak of heredity with unusually strong atavistic memories from a Mid-Pleistocene ancestor. He describes how his childhood dreams lacked any human figures, and how studying evolution in college provided the key to understanding these experiences as inherited racial memories rather than reincarnation. ## Themes in this chapter ### Racial Memory and Atavism The narrator elaborates on his theory of racial memory, describing himself as a 'freak of heredity' with an unusually strong atavistic other-personality that recalls ancestral experiences. ### Evolution and Human Origins The narrator uses evolutionary concepts, such as the falling dream as a racial memory from tree-dwelling ancestors, to explain his dreams and the origins of human instincts. ## Character check-ins ### The Fire People Mentioned as a threat from which the narrator's dream-self fled. ## Key lines > I have this other-personality and these complete racial memories because I am a freak.

Instincts are inherited memories passed down through generations. _Key theoretical statement linking instinct to heredity._ > Evolution was the key. It gave the explanation, gave sanity to the pranks of this atavistic brain of mine.
