Bill Mesler & H. James Cleaves II - A Brief History Of Creation (Norton & Company, 2016) ****


The title of this book has to be taken literally: it's a history of all the theories about the origin of life, a fascinating subject that has boggled the minds of the smartest scientists in the world since time immemorial, with the exception of course of religions.

They start with the ancient Greeks - where else? - and then guide us through the centuries. It's a wonderful overview of scientific questioning, research and discovery, but at the same time the book offers a good insight in some primitive and wrong theories, including the very longstanding error that animals could arise out of nothing. Aristotle already concluded that eels just came to existence out of water, because he couldn't figure out how they migrated to the Mediterranean (unaware of their travels to the Sargasso sea), but even in the 19th century, people believed that mice could come to life just out of hay.

Luckily, cleverer minds made interesting discoveries. Belgian alchemist Jan Van Helmont came to the conclusion that all life came from eggs. Dutch weaver Anthony van Leeuwenhoek discovered microbes in the placque from his teeth that he put under his newly developed microscope.

The more interesting and in-depth analysis is the one from Darwin to Crick and Watson, followed by the initially controversial theories by Carl Woese into the real origins of life by studying DNA. He shook the foundations of scientific thinking by adding new, and more archaeic life forms into our general notion of how nature is organised, and how evolution works.

Today, we know that life must have come to existence out of the most basic amino acids, small chemical entities that create proteins. In lab tests, self-replicating RNA has been developed, yet never without the presence of a copying protein. Bacteria were discovered in the most uninhabitable places on earth, such as the hot water vents at the bottom of the ocean. Expectations are that in such extreme conditions chemical reactions have come into play to start the replicating process. But how, that still remains a mystery.

"A Brief History Of Creation" is an easy to read, and fascinating overview of the theories of creation throughout the ages. It demonstrates again how important science is to come to an understanding of our world. The biggest challenges remains to make sure that everybody in the world because aware that life was not created in the garden of eden.
