Suppose that through genetic diversity some individuals in a species of 
insect like light more than do others. These individuals will seek 
lighter areas in their environement and breed with other individuals who 
also prefer light. Over time wont these become a new species, and not 
necessarily with pressures of natural selection? Is this another mechanism 
for evolution?
