At molecular level, evolutionary change is unpredictable

Using modern molecular tools and fieldwork, University of Nebraska-Lincoln biologist Jay Storz and colleagues have demonstrated for the first time that different species can take different genetic paths to develop the same trait. The team’s findings appear in the Oct. 21 issue of the journal Science.

“Storz and his team tested the hemoglobin proteins from numerous high-altitude bird species and identified which differences, or mutations, in the proteins’ makeup were responsible for the high-altitude trait. In most cases, the change in protein function among the different species was caused by different mutations. What this indicates is that there are many possible mutations that can all produce the same phenotypic effect”.

We may already know all this from studies of dwarfism and albinism?

There are at least 11 different genetic mutations that lead to dwarfism in humans.
