What is the current time period?

Earth’s geologic epochs—time periods defined by evidence in rock layers—typically last more than three million years. We’re barely 11,500 years into the current epoch, the Holocene. But a new paper argues that we’ve already entered a new one—the Anthropocene, or “new man,” epoch.
