Our emphasis is on both the evolutionary stability of attenuation, i.e., whether adaptive evolution reverses the attenuation, and on our ability to predict the evolutionary response to the reorganization.
RuO2 coatings deposited on nickel substrates were subjected to different electrochemical treatments such as hydrogen evolution, oxygen evolution, or reverse currents in 8 M NaOH at 90 °C.
I get the sudden feeling that evolution has reversed -- I too am a fish, a fish among smaller fish.
Examining the evolution of one protein, a team of scientists declares the answer is no, saying new mutations make it practically impossible for evolution to reverse direction.
All eyes, not just those of humans, are influenced by historical contingency and constraints, and moreover once adaptation has begun down a particular path for example, in the formation of a camera-type, compound, or pinhole eye it can be very unlikely for evolution to reverse course and change to a different avenue.
By changing the speed of the tape, wide variations in the pitch and tempo of the recorded material can be effected; by playing the tape backward, a sound's evolution can be reversed.
In a final step, we explore the potential for, and timescale of, fisheries-induced evolution to be reversed through reserve establishment.
However, one area that remains controversial is whether it is possible for evolution to be reversed so that an organism or molecule returns to a previous form.
Whereas trends toward increasing structural complexity have often been reversed during evolution, reproductive behaviour patterns in many phylogenetic (i.e., evolutionary) lines have become more complicated in order to enhance the opportunity for fertilization of eggs and maximum survival of offspring (see sex).
However, this pattern was reversed as evolution progressed: the last two assay points showed significant differences (PE > DE, Fig. 3).
