For 75% of Neanderthals, Life was as Bitter as it Is for 75% of Modern Humans

BBC NEWS | Science & Environment | 'Taste test' for Neanderthal DNA
DNA analysis of ancient remains shows that Neanderthals shared with modern humans the gene that gives the ability to taste bitter flavours.

Most people find the chemical, known as PTC, very bitter, but 25% cannot taste it at all.

The two groups have different taste receptors on their tongues.

Analysis of the 48,000 year-old bone shows that the genetic variation responsible for this difference also existed in Neanderthals.
