How do scientist estimate the number of nucleotide changes that have taken places in a gene since two species diverged from a common ancestor?

Both organisms' DNA is sequenced, and then compared to one another. The number of nucleotide changes is literally counted (though with a computer). It is an estimate because of genetic diversity within a species

What does comparing DNA fromo two species tell scientists?
By looking at different, small sections of DNA scientists can identify how many of them are shared exactly with another species and how far others diverge. The possibility of having the same genetic code due to convergent evolution, rather than it coming from a shared ancestor is so minute that scientists can say with a large degree of certainty how closely species are related

What do scientist use to estimate how long ago various groups of organisms diverged evolutionarily from one another?
carbon dating
What uses mutation rates to measure evolutionary time?
"Molecular clocks" can be used to estimate the time at which two lineages diverged. Often, the calibration of the clock uses fossil evidence to gauge a timeframe for the existence of a common ancestor of a number of lineages. From this, an average mutation rate can be calculated. This average mutation rate can then be used to estimate the timeframe for further branching points in the genealogy of the lineages in question.For instance, fossil evidence could be used to establish a timeframe for the existence of a common ancestor to all great apes. By dividing the sum of all differences in a particular genomic sequence for all great apes by the time between then and now, we get an average rate. We can then take the differences between that genomic sequence in men and Neanderthals to estimate when Neanderthals diverged from us.

What technique do biologists use to estimate how long ago species separated from a common ancestor?
The best way to estimate the time of divergence of species from a common ancestor is by genetic analysis; aside from the functional evolutionary changes in genetics, there are also accumulated random genetic changes called genetic drift, which are a good indication of the amount of time that has passed.

Age, weight, blood tests.
