The Smithsonian Institution has released an iPhone app to allow users to morph their faces into those of Neandertals. Explains the Christian Science Monitor:
First you upload a portrait of your face and line up the image with markers for the eyes, nose and mouth. Next, you choose which human species you'd like to become, including: Homo floresiensis who lived between 95,000 and 17,000 years ago; Homo neanderthalensis  who lived 200,000 to 28,000 years ago; and Homo heidelbergensis who lived 700,000 to 200,000 years ago.
Expect your nose to inch up in size in the resulting MEanderthal image .
"Neandertal faces tend to have much bigger noses," said Briana Pobiner, a paleoanthropologist at the Smithsonian Human Origins Program. "Big noses were good for humidifying and warming glacial, ice age air."
