Ancient Megafauna Extinction Linked to Human-Induced Fires in California

Massive Ice Age mammals, known as megafauna, that once roamed Southern California over 13,000 years ago likely disappeared due to wildfires set by humans and an ecosystem made vulnerable by climate change, according to a study by researchers from UCLA and the La Brea Tar Pits and Museum. The evidence suggests that unprecedented fire activity, along with human presence and a changing climate, led to the extinction of these large animals. The study draws a parallel between the past landscape transformation and the current conditions that contribute to climate change and devastating wildfires. Researchers hope further studies of specimens from the tar pits can provide insights into the long-term impacts of climate change.
