Review: Evolution: How We and All Living Things Came to Be
Daniel Loxton has crafted an
adventurous story about evolution.
Not only is the science accurate
but it is also presented in a
way that draws kids of all ages into
Darwin’s “mystery of mysteries.”
This book took me back to childhood
Saturdays in the library
immersed in a journey that I did
not want to end. The adventure
starts with a dinosaur nearly leaping
out of the page, and then
Loxton introduces us to the usual
evolutionary suspects — Darwin
and Cuvier — and unexpectedly to
a young woman, Mary Anning, who
hunted fossils for a living. The
inclusion of Anning is perfect for
young girls wondering what
adventures to pursue in life —
teaching them that they too can
indeed take on science.
Our guide wastes no time in
providing a clear description of
the mechanism of evolution in
three easy-to-understand steps:
struggle among and between individuals,
variation and natural selection
acting on it, and the passing
on of characteristics to the next
generation, and voila! evolution
explained. From that point, Loxton
gently guides us along the trail of
Darwin’s big idea — to the land of
“Zooks” (imaginary zebra-like
beasts), where we learn how
species can split, and on to stories
of adaptations as answers to questions
posed by nature. Here a gorgeous
pterodactyl flies off the
page, and there the first amphibians
crawl on to dry land to mingle
with the first vascular plants, portending
the later invention of trees
with trunks as an answer to the
question of how to trap the most
light to make the most food. Pretty
soon we are face to face with our
own ancestors. Loxton makes that
speciation event seem as natural as
flowing water, and then unobtrusively
points out that the species
resulting from those early ancestors
has control of the destinies of
all other species — indeed that of
the whole planet — through technological
evolution.
Loxton does miss several teachable
moments that could provide
young students with non-magical
and logic-strengthening insights
on how life on the planet is interconnected.
One of the omissions is
a page devoted to the actual molecular
basis of evolution — a depiction
of the elegance of a DNA molecule.
Elementary students easily
grasp the concept of molecular
structure and the energetic glue
that holds them together, and this
understanding can then be applied
to the concept of the material
basis of evolution — that if a biological
characteristic is not written
in the codes of the molecule DNA
then we are not discussing evolution
by natural selection.
One other major oversight is
the lack of explanation of the role
of photosynthesis as the energetic
basis of virtually all life.
Students need to understand
early on that they are the product
of light, and some pages devoted
to the story of light and its connection
to life would have made
evolution so much less magical to
young minds. Providing this
would have required explaining
photosynthesis and respiration,
illustrating how the laws of thermodynamics
apply to life and
thus also to evolution. This is not
as difficult a task as it might
appear. None of the fourth
through sixth graders that I have
taught in weekly lessons on biology
have been unable to understand
these ideas.
Evolution: How We and All
Things Came To Be should be an
early reading for elementary students’
science education curriculum
and a permanent part of the
classroom library. The book’s simple
lucidity, stunning art, and connected
storytelling teaches students
that they can learn science,
and it teaches them their own special
place in the grand scheme —
the “grandeur” as Darwin wrote —
of life.
