Why we have plenty of fish in the sea
Date:4/4/2012

HUNTSVILLE, Ala. -- New work from the HudsonAlpha Institute for Biotechnology, with collaborators at Stanford University and five other groups, has pinpointed evolution in action.

By determining genomic sequence from many groups of stickleback fish, the scientists were able to show specific genomic changes leading to the ability of different fish populations to adapt to new environments. "We were pleased with the ability of genomics to show us what molecular changes are important in evolutionary processes," said Richard Myers, Ph.D., president and director of HudsonAlpha.

At the end of the last ice age, marine stickleback fish were present in many waters and then became separated into different populations in lakes and streams worldwide. These populations evolved separate traits, such as number of spines, body length or eye size, which allowed them to thrive in their specific habitat.

To tie these traits to specific DNA changes, the scientists generated a reference of the threespine stickleback fish genome at high quality. "With our reference genome and genetic map for stickleback, we will now be able to use it as a model organism for future studies of adaptation and environmental selection," said HudsonAlpha faculty investigator Jeremy Schmutz.

Scientists then sequenced 21 pairs of fish that varied at different traits and compared them to each other and to the reference fish genome. Small regions of the fish genome stood out due to changes in the genomic DNA, and many of these could be related to how the fish look and behave.

Two interesting findings stood out. First, the changes between fish populations often happened not by mutations in single DNA bases, but by inversions of very large chunks of DNA on fish chromosomes. When these large inversions of DNA occur, fish can no longer breed with each other effectively and start to become separate species.

Second, the scientists saw that when evolution allowing
