Human arrival did not cause widespread island extinctions during the Pleistocene

In short: Researchers who examined archaeological and paleontological records of Pleistocene islands found no evidence that human arrival triggered widespread extinctions. While humans are often viewed as destructive agents, the data suggests that large-scale ecosystem changes did not become visible until the Holocene epoch.

This study examined the global link between human arrival and island extinctions by reviewing paleontological and archaeological records. The researchers found that extinctions during the Pleistocene cannot be clearly linked to hominins and are difficult to separate from environmental shifts.

The findings suggest that the current acceleration of extinctions is a recent phenomenon related to Holocene cultural developments rather than an inherent trait of human presence.

Why it matters: Human-driven mass extinction may be a more recent phenomenon linked to Holocene cultural shifts rather than an inherent trait of our species.
