Paperback. Etat : New. Print on Demand. This book introduces a groundbreaking theory that many lower animals do not reproduce like other species. Instead, certain creatures give birth to a form that transforms into a creature that resembles the mother. The author looked at jellyfish, polyps, and sea creatures like them to gather evidence for this theory. In these animals, the author claims to have discovered that what scientists previously believed were distinct life forms were actually different generations. They found that a polyp-like creature, previously believed to be one species, was actually a stage in the life-cycle of a jellyfish. According to the author, this is evidence that the jellyfish species was giving birth to a form that would mature into itself. This challenges the prevailing 19th-century understanding of how these species reproduced, leading to a new theory about the relationship between these generations. It is an essential read for zoologists and biologists and anyone interested in learning more about these species and the history of scientific discovery. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
