Ancient people generally made the connection between sex and babies, of course. What was actually happening, however, wasn’t understood because sex cells require a microscope even to be seen, and that doesn’t make it obvious what they’re doing. Dolnick’s tale looks at advances in various sciences and, perhaps more importantly, the religious constraints under which they operated. The idea of the atheistic scientist is a fairly new one. Up through most of the nineteenth century scientists tended to share the worldview of others that God was assumed and that religious rules applied to such mysteries as life. That’s amply demonstrated in this book. True insight was slowed down considerably by religious presuppositions.
That’s not to say Dolnick blames religion—this book is much too congenial to do any blaming. A number of ideas had to coalesce, however, before it was understood that both women and men contributed to the developing embryo. Medicine was often looked down upon by science, and religion often crossed its arms and stood in the way. Despite all that, careful observation, and putting unexpected things beneath a microscope, finally led to the answer. It was sea urchins who finally yielded up the mystery’s clue. This book will take you some strange places. The individuals described are a curious lot. For the most part they’re also a religious lot. Persistent theorizing and persistent peering through a microscope and a willingness to question convention all had to combine to answer a question as basic and profound as where it is we come from.
