Professor's hypothesis may be game changer for evolutionary theory
A new hypothesis posed by a University of Tennessee, Knoxville, associate professor and colleagues could be a game changer in the evolution arena. The hypothesis suggests some species are surviving by discarding genes and depending on other species to play their hand.



The groundbreaking "Black Queen Hypothesis" got its name from the game of Hearts.

In Hearts, the goal is to avoid "winning" the Queen of Spades (the Black Queen), which is worth a lot of points. Subsequently, players allow others to take the high-point card while they enjoy low-score tallies.

This same premise applies in evolution, the scientists say.

The system evolves toward greater efficiency? The black queen metaphor is lame. If you're shooting the moon she has a different meaning.

Specilization and interdependence would be better and more accurate descriptions. Queen of Spades.... good grief. They have to keep up the appearance of evolution as a version of The Hunger Games rather than that life tends toward cooperation.
