Hard evidence of evolution: a five-year study shows that
plants may quickly lose important traits through evolution soon after insects
are removed from the environment
At first blush, many people would probably love to get rid
of insects, such as pesky mosquitoes, ants and roaches. But a new study
indicates that getting rid of insects could trigger some unwelcome ecological
consequences, such as the rapid loss of desired traits in plants, including
their good taste and high yields.
