Darwin surmised that over millions of years, these small changes would accumulate, giving rise to the myriad of species seen today.

However, changes accumulate between more distantly related species by processes that include horizontal gene transfer and gene loss.

The years and changes accumulate.

All these small changes accumulate to something big.

When the changes accumulate, the forecasted result may not justify the original proposed investment in the project.

Darwin introduced the idea that natural selection was creative in giving direction to a process of evolutionary change in which small hereditary changes accumulate.

Now that we can sequence genes and genomes, we know precisely how evolutionary changes accumulate.

It was you who argued that significant changes can accumulate only in neighboring.

However, with a selection operation, the utility of content has a tendency to improve over time as beneficial changes accumulate.

But the change between generations does not accumulate.
