Paperback. Condizione: New. Print on Demand. This book posits that the evolution of teeth, specifically cusps, in mammals occurred differently than previously believed. The author argues that the primary cusp is on the outer side of the upper molars in primitive mammals, and that the shifting of cusps to form triangles occurred independently in different groups. The book supports this theory with evidence from Mesozoic mammal teeth, which challenges the widely accepted tritubercular theory. By presenting a new understanding of the evolution of mammalian teeth, this book contributes to the ongoing scientific understanding of the history and diversity of these animals. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
