Paperback. Condición: New. Print on Demand. This book explores the history of Salpa, a pelagic animal adapted for life in the ocean's open waters. Through its evolution, the author reveals how Salpa's adaptation to a sessile lifestyle is an inherited trait from bottom-dwelling ancestors rather than a consequence of its pelagic e…xistence. The author argues this is unusual; most highly organized animals owe their structure to competition with bottom or shore-dwelling species. The author posits that all highly organized marine life, despite their capacity for rapid movement, originated in the ocean's depths and have since adapted to pelagic life, unlike simpler pelagic organisms. This challenges the commonly held belief that pelagic life is the most primitive form. The author supports this perspective with evidence from embryology, paleontology, and the structure and habits of living animals, positing that primitive vertebrates lived near the ocean floor and that the early evolution of vertebrate classes occurred there. The author's analysis also traces the origin of the crustacean group to copepods, primitively pelagic organisms. The book concludes that the insights provided on the evolution of Salpa have significant implications for our understanding of the history of life on Earth.
