Life Ascending

IDEA 1
Ten inventions made complex life
Lane describes ten great inventions of evolution, from the origin of life to death itself. He tells how scientists have pieced together the history of each, using new evidence from biochemistry and genetics.
IDEA 2
Life began with chemistry
Lane explores how life might have started from chemical reactions in deep-sea vents. He argues that energy flowing through these vents could have driven the first steps of life. Chemistry came first, and biology followed.
IDEA 3
DNA stores life's instructions
Lane describes DNA, which stores genetic information in a code. He explores how such a code might have evolved from simpler molecules. The same code is used by almost all living things, which hints at a shared origin.

IDEA 1
Energy explains life's shape
Lane argues that energy, not just genes, is key to understanding why life is the way it is. How cells make and use energy, in his view, shaped all of evolution.
IDEA 2
Cells run on proton gradients
Lane explains that all living cells make energy by pumping protons across membranes, creating a gradient like water behind a dam. This strange method is shared by every form of life.
IDEA 3
Life may have begun in vents
Lane argues that life likely began in alkaline hydrothermal vents on the sea floor. These vents had natural proton gradients that early life could have used. In this view, the vents gave early life a ready source of energy.
