I need a summary of Chapter Two?

In Chapter Two, Pollan presents the tulip, with a heavy focus on its flower. The chapter considers the entire genus Tulipa and does not mention any of the roughly 100 species comprising it. The text considers the evolution of tulips and the co-evolution of humans and tulips but unfortunately does not elucidate the complexities of evolutionary theory at the level of the genus—a major failing. A rudimentary explanation of tulip natural history is presented. This is supplemented with a recounting of the establishment of the tulip as a garden flower in Europe with a special emphasis given to Holland, especially during the period of so-called tulipomania in the early 1600s. A more concise account then focuses on the tulip in Turkey during the early 1700s. The tulip is said to have exerted a decisive impact on human evolution because it is able to satisfy H. sapiens' desire for beauty.
