A living egg, with its warmth, its purity, and its sleeping potential, is a wonder. Who has not had the experience of peering down on the nest of a bird and being shocked by the sight of this uncanny perfection contrasted with the rough fabric of the nest?
An egg is a mechanical device used to transport and protect a living embryo. It is an architectural exercise in the conservation of space and in structural integrity. It is a vehicle for traveling down the fallopian tube and eventually out into the cold hard world, and a vehicle for traversing time - a time machine that can reconcile twenty million years in only twenty-eight days.
There is a wonderful principle in evolutionary biology known as Haeckel's biogenetic law that is stated simply: Ontogeny recapitulates phylogeny. That is, every oganism must retrace its evolutionary development from a one-celled organism to its contemporary manifestation as it develops from fertilization to birth. Although an oversimplification, this concept has valid applications. As an embryo develops, it begins with simple mitosis - one cell dividing into two. There is then a predictable progression through stages, each of which represents a rung on the phylogenetic ladder. A fetal pig will pass through successive developmental stages whereby it will share features with and be scarcely discernible from the fish, the amphibian, the reptile, up the evolutionary path to a stage representing its primitive mammalian ancestry. Only then will it begin to find its particular biological identity as a pig. Up to that point it is bound to revisit each ancestral stage of its development.
This principle, of course, holds us biologically accountable, as well. Evolutionary development is a process of building on existing attributes, not of starting from scratch. Every structure in our body from our skeleton to our DNA serves as testimony to this principle. We are a walking paleontological repository. This is why the skeleton of a frog laid next to that of a man, with the exception of size is bone for bone very much the same - a quantitative difference only. We are a frog run amock. We have to biologically retrace our steps through antiquity every time one of us is conceived."
