The Isthmus of Panama formed three million years, scientists have found out. This contradicts recent studies that pushed this date back to millions of years before. The Isthmus of Panama – the narrow stretch of land lying between the Caribbean Sea and the Pacific Ocean and linking North and South America – has long fascinated scientists.
(From International Business Times / by Lea Surugue)– As a physical barrier between the Pacific and Atlantic Ocean, the Isthmus would have had an important impact on natural life when it formed, restricting marine species movements but promoting North-South land migrations – bringing together animals that had existed separately from one another since the Mesozoic Era some 66 million years ago.
Understanding the Isthmus’ formation is thus a crucial step in understanding how and why marine life in the Atlantic and Pacific oceans started evolving independently from each other, as well as how the terrestrial mammals on the American continent became diversified. Read the full story »
