A new hypothesis counters popular evolutionary thinking that living organisms evolve by adding genes rather than discarding them
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.
