The factor that contributed to the success of some mammals during the K-Pg mass extinction event is: The ability to regulate their body temperatures in the face of reduced sunlight and colder temperatures. This physiological adaptation allowed mammals to survive in the harsher environmental conditions that resulted from the soot and ash blocking sunlight, which led to colder temperatures and disrupted ecosystems.
During the K-Pg mass extinction event, soot and ash were thrown into the atmosphere, darkening the sky for months. Some mammals were able to survive and proliferate. Which factor contributed to this success? (1 point)
• There were new predators because the dinosaurs were instantly killed.
• Many mammals developed the ability to fly, allowing them to escape the impact site.
The ability to regulate their body temperatures in the face of reduced sunlight and colder temperatures.
• A decrease in oceanic and lake habitat, leading to marine mammal evolution.
