Carl Zimmer Life Quotations

At long last, we may be returning to the original two-sided sense of the word virus, which originally signified either a life-giving substance or a deadly venom. Viruses are indeed exquisitely deadly, but they have provided the world with some of its most important innovations. Creation and destruction join together once more.

I'm really interested in the history of life in general. How life began to how birds evolved to what our ancestors looked like.
