Is biotic diversity at equilibrium, or are species still expanding their ranges from
glacial refuges, so that the current composition of communities is still affected by
history? In some cases community composition may still be recovering from the ...

Thus mutation by itself is a very weak evolutionary force. The gene frequency
reaches equilibrium and is no longer changing when AqlAt = 0. The equilibrium
frequency q is found by solving for q in the equation A4/Af = 0 = k(1 - q) - vq and
is q ...

A ball balanced on the tip of a pool cue is at equilibrium, but the slightest
disturbance will move it to a new position, so the cue tip is an unstable
equilibrium point to which the ball will not return. Some genetic equilibria are
unstable. Conversely ...
