totally agree
the only thing I wished he made a note of was
1. how such a small portion of dna is responsible for how we look (differences in skin color and physiognomy for example and the literal analogy or metaphor of that the book should not be judged by the cover) and how much simpler looking creatures sometimes have larger and more complex dna sequences then much more complicated looking ones. I always found these bits of factoid amazing considering how much homo sapiens value appearance in their social interactions.
A grain of rice has more DNA sequences than we do. But then again if you stuck us in water and forced us to eat sunlight we would die.
