"Darwin’s theory of evolution is often unfortunately associated with the phrase ‘Survival of the Fittest’. So much so, that anyone who doubts the former is therefore often regarded as denying the self-evident truth of the latter.
But a University of Exeter press release has reported that when researchers multiplied bacteria in the laboratory over hundreds of generations—“about 3,000 years in human terms”—the result was a surprise.
“It had been believed that the genome of only the fittest bacteria would be left, but that wasn’t their finding”, reported the press release.
It went on to say instead that the resulting bacterial population “challenges our current understanding of evolution” because “both fit and unfit” bacteria were still present.
Thus, “we discover a new principle, one in which both the fit and the unfit coexist indefinitely.”
