Investigate the endless variety of sexual expression and the powerful hold sex exerts over almost all living things. And discover why, in evolutionary terms, sex is more important than life itself.

From the development of the four-limbed body plan, to the journey of animal life from water to land, to the emergence of humans, "Great Transformations" focuses on the important evolutionary changes that triggered Earth's incredible diversity.

Five mass extinctions have occurred since life began on Earth. Are humans causing the next mass extinction? And what does evolutionary theory predict for the world we will leave to our descendants?

2001 is a story of evolution. Sometime in the distant past someone or something nudged evolution by placing a monolith here on earth (presumably elsewhere throughout the universe as well) Evolution then enabled man to reach the moon's surface where he finds yet another monolith, one which signals the monolith-placers that we have evolved that far. Now a race begins between computers (HAL) and man (Bowman) to reach the monolith-placers, the winner will achieve the next step in evolution, whatever that may be.

A firefighting cadet, two college professors, and a geeky-but-sexy government scientist work against an alien organism that has been rapidly evolving ever since its arrival on Earth inside a meteor.

The Dictyostelia are soil amoebae capable of extraordinary feats of survival, motility, chemotaxis, and development. Known as the "social amoebae," these organisms have been the subjects of serious study since the 1930s. Research in this area has been instrumental in shaping general views of differentiation, morphogenesis, and communication. Beginning with the history of Dictyostelids, this book considers the problems of the evolution of this multicellular organism.
