Presents a visual account of human development, from DNA to stem cells. This book includes studies of hormones, conception and embryonic development, and the growth of body organs and tissues, viruses, cancer and studies of atmospheric particles.

First published nearly forty years ago, this book broke new ground, offering an unprecedented glimpse of life inside the womb. This fourth edition uses a new high-definition ultrasound technique, scanning electron and light microscopes, and advanced fibre optics to make an unparalleled record of the unseen world within our bodies.

In 1965, the author published images from inside the human uterus, the first photographs of prenatal life. This fifth edition features images that are rendered in detail utilising revolutionary new photographic technology, with the photographs themselves the dominant driving force of the narrative.

Documents the miracle of human reproduction - the egg travelling down the fallopian tube; the sperm racing to meet it; the moment of fertilization; the very first cell division; the tiny embryo attaching to the uterine wall; the growth of eyes, ears, fingers and toes; and, the moment of delivery itself.
