Researchers reconstructed olfactory receptors from the genomes of Neanderthals, Denisovans, ancient Homo sapiens, and modern humans. It turns out that people of all kinds have the same perceived spectrum of odors. However, Denisovans turned out to have a more sensitive nose than humans, while Neanderthals did the opposite.

The latter perceived body odors worse. One of the Neanderthals had a genetic mutation that reduced the ability to smell androstadienone, a chemical associated with urine and sweat. This could greatly help those living in caves close to other Neanderthals.
