Well, they could and probably do in evolutionary time.
They lived a blink of an eye ago in evolutionary time and shared the planet with modern humans.
Previous studies have suggested that the bacterium, Yersinia pestis, emerged at between 1,500 and 20,000 years ago, a blink of an eye in evolutionary time.
There are fewer well-documented instances of the second stage, presumably because this occurs fairly rapidly in evolutionary time.
The DNA differences between orca groups had not turned up before, in part because the speciation occurred quite recently in evolutionary time.
In the discussion that ensued, reader BlueSky3 commented: Hope more likely rests in examining the control systems/defence mechanisms of those carrying a hereditary cancer fault which has perhaps persisted in evolutionary time.
In evolutionary time, the few thousand years that separate us from Achilles are a blink of an eye, far too short to allow for such radical structural changes in the brain.
He observed that the distinctions between species that make sense on a single day, in a particular place, often lose coherence when you take a global perspective or begin thinking in evolutionary time scales.
The new study, by Galit Shohat-Ophir and her colleagues at Bar-Ilan UnIsraelty, in Israel, confirms that this association dates way back in evolutionary time and motivates organisms as rudimentary as the fruit fly.
[00 40 07] But that is so far back in evolutionary time that that doesn't mean we shouldn't work against that now.
But for the past 10,000 years (a blip in evolutionary time), we had to specialize and be good at one thing and in one place.
