Evolutionary biologists have long theorized that the pace of evolution quickens when a species faces great environmental stress. This idea, of course, is a tough one to âprove,â but we can see examples of it all around us. Just look at the IT security industry, where something akin to drastic environmental change is happening right now: Organized cybercrime groups are punching truck-size holes in enterprise security defenses as regulators, shareholders, and attorneys general are putting pressure on companies to lock down sensitive data. The pressure for change will make this weekâs RSA Security Conference in San Francisco less an industry shindig than a live experiment in evolutionary biology. So walk quietly and keep your field glasses handy to spot some exotic new species in these areas:
