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 a changing climate, according to a study by researchers from UCLA and the La Brea Tar Pits and Museum. The evidence suggests that extensive fire activity, along with human presence, led to the demise of these large animals. The study draws a parallel between the past landscape transformation and the current conditions contributing to climate change and devastating wildfires. Researchers hope to use specimens from the tar pits to better understand the long-term impacts of climate change.
