The spread of humans and their large and increasing population has had a profound impact on large areas of the environment and millions of native species worldwide. Advantages that explain this evolutionary success include a relatively larger brain with a particularly well-developed neocortex , prefrontal cortex and temporal lobes , which enable high levels of abstract reasoning , language , problem solving , sociality , and culture through social learning. Humans use tools to a much higher degree than any other animal, are the only extant species known to build fires and cook their food , and are the only extant species to clothe themselves and create and use numerous other technologies and arts .
It's jarringly creepy seeing human bodies like this, I gotta say. I definitely enjoy watching the world and all of its people at normal speed. [ Michael Haussman via BoingBoing ]
