STANFORD RESEARCHERS DEVELOP SYSTEM FOR FIELD TESTING MECHANISMS OF EVOLUTION: "Kingsley said they found a number of parallels between traditional laboratory genetics and the traits they examined in the stickleback populations. For example, many of the traits could be traced to major chromosome regions - indicating that evolution can occur through changes of large effect, not just as a series of small changes. Their findings also indicate that genetic control of body regions appears to be modular. "
