Although the gene sequences from human and chimpanzee remain very similar, previous studies in tissues other than the brain have shown that gene expression varies widely.

One new way that scientists study this process of cellular development — and a way in which they hope to grow replacement tissue for medical treatments in the future — is by recreating the essential features of human brains, eyes, lungs, and guts in a petri dish.
