Reminiscent of great Médoc while young, they evolve into wines that have the pungent undergrowth and truffle aromas found in great Burgundies.
Under the null hypothesis, the parameters of the PC are stable, while under the alternative hypothesis, they evolve as driftless random walks.
The molar teeth were initially thought to be tribosphenic, which would have supported a variation of Gregory's theory, but later research has suggested, while they have three cusps, they evolved under a separate process.
Because men invested less time and effort in their offspring, they evolved toward promiscuity, while women evolved away from it.
And most importantly, the power of flight arose independently in these two different classes of vertebrates; in birds while they were evolving from early reptiles, and in bats after their mammalian ancestors had already completely differentiated from reptiles.
While they have evolved to eat seals, polar bears, unlike most species, will actively hunt humans in certain circumstances especially if they're not able to access their typical prey.
So while they are clearly evolving, perhaps they are doing so more slowly than everything else.
And, more in general, which is the mechanism that allow languages to appear static while they are yet evolving?
They don't want it to be fixed and final; they want it to evolve while they're there.
Therefore, we hypothesized that there would be a difference in evolution between the two groups of sequences, with relapsers evolving to become more resistant to therapy while nonresponders would evolve less because they were initially relatively resistant.
