Press Release 11-019
Seeking Social Genes

Researchers compare insect genomes to hone in on genes associated with complex social structure

Sequencing the entire red harvester ant genome has revealed that, compared to other insects, the P. barbatus genome has significantly more genes associated with the sense of smell, as well as detection and metabolism of chemical signals. This is consistent with the fact that ants use chemical signals to communicate.
