Fit for a Purpose: Does the Anthropic Principle include Biochemistry?

Blaze a new trail of discovery in biochemistry.\nNearly a half a century after the introduction of the idea that humanity lives in a universe at the just-right location, the just-right time, and with the just-right physical constants, the anthropic principle continues to gain acceptance among astronomers and astrophysicists. Few scientists question the fine-tuning of the numerical quantities that define the universe.
But what about the unexplored areas of chemistry and biochemistry? Do we witness an equal amount of evidence for fine-tuning?
In Fit for a Purpose, biochemist Fazale Rana, fearlessly pushes the boundaries of the anthropic principle beyond cosmology. In the process, Rana invites the reader to discover the world of chemical and biochemical fine-tuning, as well as to contemplate this question:
If the universe is fit for life, and biochemical systems are fit for their role in life, is it possible that everything is "fit for a purpose"?
