To explain the mystery of how life evolved on Earth, Nick Lane explores
the deep link between energy and genes.
The Earth teems with life: in its oceans, forests, skies, and cities.
Yet there's a black hole at the heart of biology. We do not know why
complex life is the way it is or, for that matter, how life first began.
In The Vital Question, award-winning author and biochemist Nick Lane
radically reframes evolutionary history, putting forward a solution to
conundrums that have puzzled generations of scientists.
For two and a half billion years, from the very origins of life,
single-celled organisms such as bacteria evolved without changing their
basic forms. Then, on just one occasion in four billion years, they made
the jump to complexity. All complex life, from mushrooms to man, shares
puzzling features, such as sex, which are unknown in bacteria. How and
why did this radical transformation happen? The answer, Lane argues,
lies in energy: All life on Earth lives off a voltage with the strength
of a lightning bolt.
Building on the pillars of evolutionary theory, Lane's hypothesis draws
on cutting-edge research into the link between energy and cell biology
in order to deliver a compelling account of evolution from the very
origins of life to the emergence of multicellular organisms while
offering deep insights into our own lives and deaths.
Both rigorous and enchanting, The Vital Question provides a solution
to life's vital question: Why are we as we are, and indeed, why are we
here at all?
