Paleontologists have spent a vast amount of time digging up dinosaur fossils, studying them, and then slating Jurassic Park. But despite the effort, some questions still remain about our predecessors on this planet — including whether or not they were cold-blooded.
Scientists have found the reason why our body temperature is 98.6° Fahrenheit (37°C). Apparently it's the perfect balance, as it's warm enough to prevent fungal infection but not so hot that we need to eat nonstop to maintain our metabolism.
Just one more reason to fear Jurassic Park: a new study has found that, unlike modern-day reptiles, dinosaurs were likely warm-blooded. It's a trait that suggests dinosaurs were far from lumbering reptiles, and were actually quite the prehistoric athletes.
