Paperback. Condition: New. Print on Demand. This book explores the early life history of the germ cells of the brook lamprey. The author traces the germ cells from their first appearance during embryological development to the point where males and females can be distinguished by studying their germ glands. The author argues that germ cells are segregated early in development and that all the definitive germ cells develop from these early segregated cells. The author also discusses the historical and theoretical context of the origin of germ cells in vertebrates, and presents evidence for the theory of early segregation of germ cells in the lamprey. The book is a valuable resource for researchers in the fields of developmental biology and evolutionary biology, and provides new insights into the early development of germ cells in vertebrates.
