First Steps - How Walking Upright Made Us Human (Hardcover)

Humans are the only mammals to walk on two, rather than four, legs.
From an evolutionary perspective, this is an illogical development,
as it slows us down. But here we are, suggesting there must have
been something tremendous to gain from bipedalism. First Steps
takes our ordinary, everyday walking experience and reveals how
unusual and extraordinary it truly is. The seven-million-year-long
journey through the origins of upright walking shows how it was in
fact a gateway to many of the other attributes that make us
human-from our technological skills and sociality to our thirst for
exploration. DeSilva uses early human evolution to explain the
instinct that propels a crawling infant to toddle onto two feet,
differences between how men and women tend to walk, physical costs
of upright walking, including hernias, varicose veins and backache,
and the challenges of childbirth imposed by a bipedal pelvis. And
he theorises that upright walking may have laid the foundation for
the traits of compassion, empathy and altruism that characterise
our species today and helped us become the dominant species on this
planet.
