In the late 1970s, a Stuttgart zoo imported a lush, bright green seaweed for its aquarium. "Caulerpa taxifolia" was captively bred by the zoo and exposed, for years, to chemicals and ultraviolet light. Eventually a sample of it found its way to the Oceanographic Museum in Monaco, then headed by Jacques Cousteau. Five years later, while cleaning its tanks, that museum dumped the pretty green plant into the Mediterranean. This supposedly benign little plant - that no one thought could survive the waters of the Mediterranean - now covers 10,000 acres of the coasts of France, Spain, Italy and Croatia, and has devastated the Mediterranean ecosystem. And it continues to grow, unstoppable and toxic. When Alexandre Meinesz discovered a square-yard patch of it in 1984, he warned biologists and oceanographers of the potential species invasion. His calls went unheeded. At that point, one person could have weeded the small patch out and ended the problem. Now, however, the plant has defeated the French Navy, thwarted scientific efforts to halt its rampage, and continues its destructive journey into the Adriatic Sea. This text presents the biological and political horror story of this invasion. For despite Meinesz's pleas to scientists and the French government, no agency was willing to take responsibility for the seaweed, and while the buck was passed, the killer algae grew. In short, this work - part detective story and part bureaucratic object lesson - is a classic case of a devastating ecological invasion and how "not" to deal with it.

The origin of life is a hotly debated topic. The Christian Bible states that God created the heavens and the Earth, all in about seven days roughly six thousand years ago. This episode of Genesis departs markedly from scientific theories developed over the last two centuries which hold that life appeared on Earth about 3 billion years ago in the form of bacteria, followed by unicellular organisms half a millennia later. It is this version of genesis the Alexandre Meinesz explores in this engaging tale of life's origins and evolution."How Life Began" elucidates three origins, or geneses, of life - bacteria, cells, and multicellular organisms - and shows how evolution has sculpted life to its current biodiversity through four main events: mutation, recombination, natural selection, and geologic cataclysm. As an ecologist who specializes in algae, the first organisms to colonize Earth, Meinesz brings a refreshingly novel voice to the history of biodiversity and emphasizes here the role of unions in organizing life. For example, the ingestion of some bacteria by other bacteria led to the mitochondria that characterize animal and plant cells, and the chloroplasts of plant cells.As Meinesz charmingly recounts, life's grandeur is a result of an evolutionary tendency toward sociality and solidarity. He suggests that it is our cohesion and collaboration that will allow us to solve the environmental problems arising in the decades and centuries to come. Rooted in the science of evolution but enlivened with many illustrations from other disciplines and the arts, "How Life Began" intertwines the rise of bacteria and multicellular life with Vermeer's portrait of Antoni van Leeuwenhoek, the story of Genesis and Noah, Meinesz's son's early experiences with Legos, and his own encounters with other scientists. All of this brings a very human and humanistic tone to Meinesz's charismatic narrative of the three origins of life.
