«This could be a consequence of the limited variety of scents to be found in the arid, alpine meadow environment, but that doesn't explain why the yak, a species that also inhabits the Tibetan Plateau, has an increased number of olfactory receptor genes compared with cattle,» Dr Subramanian said.

For instance, in the human genome we still see the remnants of the large olfactory receptor gene family that gave our evolutionary ancestors a keen sense of smell, even though humans no longer rely on them.

First, they sequenced the same 50 olfactory receptor genes from two humans, two chimpanzees, two gorillas, two orangutans, and two rhesus macaques.

New genetic evidence shows why this is: Humans are losing so - called olfactory receptor genes at much higher rates than monkeys and apes.

Trimmer, a geneticist, studies how differences in olfactory receptor genes affect human smell perception.

More than half of the participants could not smell it and researchers found that genetic variations near olfactory receptor genes was associated with the ability to detect the smell.

Cats rely less on their sense of smell for huntings than dogs do, which is apparent from the smaller repertoire of olfactory receptor genes in the feline genome.

Antennae The butterflies have a large number of olfactory receptor genes, which, when activated in the antennae, might help them interact with other monarchs to find their destination.

To check whether this is a general primate problem, geneticist Yoav Gilad and colleagues at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the Weizmann Institute of Science in Rehovot, Israel, compared our olfactory receptor genes with those of our evolutionary brethren, the monkeys and apes.

Olfactory sensory neurons express either a class I or class II olfactory receptor gene in order to express either class I (blue) or class II (pink) olfactory sensory neurons.
