# s-gst: lastly, they indicate the generality of that

<< Lastly, [AA] indicate the generality of this phenomenon by demonstrating suppression of chaotic oscillations by coupling to a common hyper-chaotic system. These results then indicate the easy controllability of chaotic oscillators by an external chaotic system, thereby suggesting a potent method that may help design control strategies. >>

# s-evol: just three traits to explain, by Tereza & John

AA << found that just three traits explained most variation in diversification and species numbers among phyla: the most successful phyla have a skeleton (either internal or external), live on land (instead of in the ocean), and parasitize other organisms. >>

<< Other traits, including those that might seem more dramatic, had surprisingly little impact on diversification and species numbers: evolutionary accomplishments such as having a head, limbs, and complex organ systems for circulation and digestion don't seem to be primary accessories in the evolutionary "dress for success."  >>

<< "Parasitism isn't correlated with any of the other traits, so it seems to have a strong effect on its own," said Wiens [John Wiens]. >>
