In First Steps， paleoanthropologist Jeremy DeSilva explores how unusual and extraordinary this seemingly ordinary ability is。 A seven-million-year journey to the very origins of the human lineage， First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities， our thirst for exploration， our use of language–and may have laid the foundation for our species’ traits of compassion， empathy， and altruism。 Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia， DeSilva brings to life our adventure walking on two legs。 First Steps examines how walking upright helped us rise above all over species on this planet。

First Steps includes an eight-page color photo insert。
