Summary:
A debate over when the gap between North and South America closed has opened a rift in the scientific community. Analyzing data from rocks, fossils and genetic studies, researchers have assembled a defense of the conventional view that the Isthmus of Panama formed about 3 million years ago. The work rebuts papers published last year that concluded that the continental connection began millions of years earlier.
"Age of Americas' Hookup Debated" is from the September 17, 2016 issue of Science News.
