  • Summary

    Volume 1 of The Cambridge History of Global Migrations documents the lives and experiences of everyday people through the lens of human movement and mobility from 1400 to 1800. Focusing on the most important typologies of preindustrial global migrations, this volume reveals how these movements transformed global paths of mobility, the impacts of which we still see in societies today. Case studies include those that arose from the demand for free, forced, and unfree labor, long- and short-distance trade, rural/urban displacement, religious mobility, and the rise of the number of refugees worldwide. With thirty chapters from leading experts in the field, this authoritative volume is an essential and detailed study of how migration shaped the nature of global human interactions before the age of modern globalization.

  • Strontium isotope evidence for the age of Eocene fossil whales of Kutch, western India

  • The Indian subcontinent is widely considered to be the birthplace of whales (Cetacea), and the middle Eocene Harudi Formation of Kutch has long been known to be a major source of early whales. The Kutch cetaceans are of critical importance in understanding the evolutionary transition of whales from land to sea. Strontium isotope analysis of marine biogenic carbonates from the Harudi Formation was conducted to obtain a numerical age of the whale-bearing strata. Although the measured 87Sr/86Sr ratios (0.707742 to 0.707764) correspond to two distinct age clusters of 46–47.5 Ma or 41–42.5 Ma, we prefer the latter, late Lutetian, age cluster.
