Humans are the smartest living creatures on Earth. Well, maybe not "smart" entirely, but we're at least the most advanced creatures when it comes to brain development, and scientists really want to know why. Evolution, sure, but the actual nuts and bolts of why our brains develop differently than those of other great apes and chimpanzees have been a mystery for a very long time. Now, new research published in the journal Cell offers the first real insights into how human brain growth is different than our nearest mammal relatives.

Humans are capable of a great many things due in large part to the physical size of our brains. Our brain organs are simply much larger than that of chimps and apes, and the huge number of neurons our brains have compared to primates is what helps to set us apart. By growing tiny samples of brain tissue in the laboratory, researchers were able to spot a key difference in the early development of human brains when compared to chimps and apes.
