Even in a crowd, you remain unique, UCLA life scientists report
Date:2/22/2011

"Am I just a face in the crowd? Is that all I'll ever be? ... Do you think I stand out?"
The Kinks, "A Face in the Crowd"

It may seem paradoxical, but being part of a crowd is what makes you unique, according to UCLA life scientists.

Biologists Kimberly Pollard and Daniel Blumstein examined the evolution of individuality personal uniqueness by recording alarm-call vocalizations in eight species of rodents that live in social groups of various sizes. They found that the size of the groups strongly predicted the individual uniqueness in the animals' voices: The bigger the group, the more unique each animal's voice typically was and the easier it was to tell individuals apart.

Their research will be published as the cover article in the March 8 print issue of the journal Current Biology and is now available online.

The findings resulting from six years of research by Blumstein, professor and chair of ecology and evolutionary biology at UCLA, and Pollard, who conducted the research as a doctoral student in Blumstein's laboratory may help explain a fact critical to the everyday lives of humans and other social creatures: why everybody is different.

The reason, the researchers say, is due to a "Where's Waldo" effect in which it is difficult to pick one individual out of a crowd, and the bigger the crowd, the harder it is.

"But humans and other social creatures can't just give up when crowds get large," said Pollard, the study's lead author. "We still must be able to identify our friends, our family and our rivals within that crowd."

The species that had to contend with bigger crowds did so with more unique voices, the researchers found. The larger the social group, the easier it was to tell any two individual animals apart.

"Nature has solved the 'Where's Waldo' problem by endowing highly social creatures with more unique features, which helps them find their pals in t
