Two groups of snowshoe pioneers diverged early on, setting patterns that can still be seen today.

At that point, the little group diverged.

Thus the isolated group may, quite rapidly, diverge from the base population.

It is unfortunate that of these too, few good fossils are known, as they date to about the time when the modern groups presumably diverged.

At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds.

In 2013, a 50-million-year-old fossil bird unearthed in Wyoming was found to be a predecessor to both hummingbirds and swifts before the groups diverged.

The difference in gene frequencies between the original population and colony may also trigger the two groups to diverge significantly over the course of many generations.

The three form a monophyletic group within the genus, having diverged from ancestors of the Grey Butcherbird around five million years ago.

These two groups largely diverged over the years.

This group may have diverged from the Near East group some 35,000 years ago.
