Shadows of Forgotten Ancestors (Unabridged‪)‬

World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. It shows with humor and drama that many of our key traits - self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics - are rooted in the deep past, and illuminated by our kinship with other animals.

Astonishing in its scope, brilliant in its insights, and absolutely compelling, Shadows of Forgotten Ancestors is a triumph of popular science.
