Neanderthal Skull Simulation (IMAGE) New York Institute of Technology Caption Image illustrates the difference in skull and nose shape in the three human species tested. Airflow is color-coded for temperature (warmer colors = warmer air, cooler colors = colder air). Lines indicate that Neanderthal and modern-humans likely diverged from an ancestor very close to Homo heidelbergensis.
