Clever. An interesting take on instructing genetics. The "alien observer" viewpoint gave the author a reason to harp on earthly life's construction and human history in an interesting and less inflammatory way than might otherwise have been done. So far as I can tell, the science is solid, presented well - not dry, and with a sense of humour. The illustrations were fabulous - clean, well-drawn panels, with plenty of details and often embellishments that served to at least decorate and often amuse.
