Surviving Natural Selection

According to Charles Robert Darwin natural selection favors the most fit and adoptable organisms around. However those species which survive may not always be optimal form of life. The researchers from The University of Texas at Austin, led by evolutionary biologist Dr. Matthew Cowperthwaite have shown that what may be good in the short run, may hinder evolution in the long run. Cowperthwaite explains "Some traits are easy to evolve - formed by many different combinations of mutations. Others are hard to evolve - made from an unlikely genetic recipe. Evolution gives us the easy ones, even when they are not the best." This research has been conducted using computer models of RNA molecules evolving by mutation and natural selection.

A pitty that we don't have an example. Still it is interesting. Reminds me of corporations when it is not the most talented guy to get a promotion.
