Scientists track primate evolution via RNAs
Rome wasn’t built in a day. Neither was the human brain. The intricate organ was crafted over millions of years before it developed into the functionally sophisticated masterpiece it is today. Just like the numerous workers who toiled in the hot Mediterranean sun to construct the roads, buildings and aqueducts of Rome, countless different biological components labored for years to construct the neurons, lobes and synapses of the human brain. One class of these biological laborers is microRNAs.
