Is there any evidence of a high mutation rate during these changes?

The second area where environment could come into play is the mutation rate itself.

It turns out there are many ways to get high mutation rates.

It really makes you wonder if the mutation rate out here is higher than the standard rates.

Except that you can do the math on mutation rates.

The mutation rate used is based on that of family groups with known most recent common ancestors.

The mutation rate has been observed to vary with time.

Better estimates of mutation rates in these viruses are needed.

So long as the proportions of each form is above mutation rate, then selection must be the cause.

The only thing higher than the mutation rate is the incidence of alcoholism.

As a result, observed mutation rates tend to increase in an expanding population.

On the number of the gene loci and the total mutation rate in man.

They are free to evolve at the mutation rate.

The mutation rate is also thought to be faster in recent times, since the beginning of the Holocene 11,000 years ago.

An organism's mutation rates can be measured by a number of techniques.

There are three theories on what determines the evolution of mutation rate.

Mutation rate in body and brain is then determined.

By far the shakiest part of the calculation is the average mutation rate.

Both researchers doubt that any species could sustain such a mutation rate indefinitely.

And, seemingly, the radiation background was high, which led to a corresponding mutation rate.

What kind of stable civilization can they build with a mutation rate that high?"

Perhaps were the mutation rate of bacteria higher their communities would become supracritical.

Moreover, mutation rates seem to change with the physiological state of the organism.

The underlying mutation rate used by the geneticists is more questionable.

Population bottlenecks thus tend to slow down observed mutation rates.
