But even something as ephemeral as the finger-thick down on this drake's belly seemed utterly suffused with time, the evolutionary time needed to create it.
Agaba, Cavener, and their colleagues estimate that the two species diverged about eleven and a half million years ago, fairly recently on the evolutionary time scale.
The few years between now and 2100 represent only a couple generations for the turtles and is just a blink in the evolutionary time scale.
That may not sound like much for a family unit, but it represents a "huge" effect on the evolutionary time scale, says Fieder.
As such, the fossil record is mute on the subject treated here, but it does provide the evolutionary time in which the groups in question diverged.
New research shows that cells in a green alga called Volvox may have learned to cooperate much earlier than thought, shifting the evolutionary time frame for this model organism back hundreds of millions of years--a somewhat controversial finding.
If the time scale for ambipolar or Ohmic diffusion is large compared to the evolutionary time of a system, the magnetic field is 'frozen' into the gas and moves with it (but see Maki and Susa 2004, 2007).
In such a case, the two variances decrease throughout the evolutionary time course, indicating increase in robustness.
(ii) Vg∝Vip during the evolutionary time course under a fixed noise strength σ(>σc) and a fixed mutation rate.
Synonymous substitutions may be used as a molecular clock for studying the evolutionary time of highly conserved sequences [29].
According to the evolutionary time estimated by Thorne and Kishino's approach (Table 2), the three groups are estimated to have diverged in the Miocene, when climates changed markedly.
