Extinction
Study challenges narrative of accelerating extinction rates
A new analysis of 500 years of extinction data reveals that species losses peaked about a century ago and have since declined, contradicting assumptions of a rapidly worsening crisis. Researchers from the University of Arizona found that past extinctions were mainly driven by invasive species on islands, while current threats center on habitat destruction on continents. The study emphasizes the need for accurate assessments to inform conservation efforts.
Dinosaurs thrived until asteroid impact, study finds
A new study challenges the idea that dinosaurs were declining before their extinction 66 million years ago. Researchers found evidence of thriving dinosaur communities in New Mexico right up to the asteroid strike. The findings highlight distinct regional ecosystems shaped by climate.
