OK, this isn't a very thrilling blog but my eye is always caught by Nature's little intricacies, all that hard work and design. A green finch flew into one of our windows yesterday, killing itself. What is so striking about birds when examined very closely, is the sheer beauty of the feathers, down to the smallest details. It is so hard to be a very strict Darwinian when one's heart yearns for a designer. Dogs are, if I may be FRANK for a moment, an example of the very best of the designer's handicraft.
