Today’s rare meteorites were once common

Four hundred and sixty-six million years ago, there was a giant collision in outer space. Something hit an asteroid and broke it apart, sending chunks of rock falling to Earth as meteorites since before the time of the dinosaurs. But what kinds of meteorites were making their way to Earth before that collision? In a new study in Nature Astronomy, Field Museum scientists have tackled that question by creating the first reconstruction of the distribution of meteorite types before the collision.

Ant Genomics Help Reshape Biological History of the Americas

Scientists have long believed that the Isthmus of Panama emerged from the ocean three million years ago, triggering a massive interchange of species between the Americas in its wake. However, recent conflict in both geological and biological literature suggests that this simple story is insufficient to explain the available evidence.
