Odour 'may help sniff out partners'

Scientists found mandrills can use body odour to identify suitable mates
12 April 2012

When it comes to choosing a partner, smell may be just as important as good looks, research suggests.

Scientists found mandrills - a primate cousin of humans - can use body odour to identify suitable mates.

An international team found an explicit link between a cluster of genes that play a key role in the immune system and an individual's smell.

And Dr Leslie Knapp from the University of Cambridge, who led the research, said the findings lend support to the theory humans may also be able to "sniff out" a good mate.

Dr Knapp, from the department of biological anthropology, said: "Our results strongly suggest that smell allows mandrills to transmit information about their own genetic quality and similarity to one another.

"By using smell they can then identify potential partners with the appropriate genes.

"What we can infer for humans is that there are some very old behaviours at play here.

"Our early ancestors may have relied on smell in a similar way, and although we may think choosing a partner has more to do with looks or sound, smell can play an important role in the process."

The findings, published in the Proceedings of the Royal Society B, were produced as part of an ongoing research project funded by the Leverhulme Trust.

The team investigated the "major histocompatibility complex" or "MHC" genes - a diverse cluster of genes that play a key role in the immune system.
