When it comes to causing extinctions, early humans were likely not the jerks that we are today, a new study finds.

Early humans relatives have lived on islands since the early Pleistocene epoch (2.6 million to 11,700 years ago). But widespread extinction on islands can largely be traced back to the past 11,700 years during the Holocene epoch, when modern humans began wreaking havoc there — overhunting, altering habitats and introducing invasive species, the researchers found.
