Differences in water temperature can create new marine species

Warm and cool water temperatures over a long stretch of coastline cause new species of marine fish to evolve without being isolated from similar types of fish nearby, according to a new international study. The findings challenge the long-held belief that new marine species can only evolve in isolated environments and provides a glimpse into the early stages of species formation in the sea.
