One Greek couple touring Germany went to live elsewhere

Usage examples of migrated.

They had migrated down through the Old World to inhabit the dense tropical forests of Asia, and here in Africa.

As we have seen in the last chapter that some forms have retained nearly the same character from an enormously remote geological period, so certain species have migrated over vast spaces, and have not become greatly modified.

In the case of those species, which have undergone during whole geological periods but little modification, there is not much difficulty in believing that they may have migrated from the same region.

Undoubtedly there are very many cases of extreme difficulty, in understanding how the same species could possibly have migrated from some one point to the several distant and isolated points, where now found.

The answer, as I believe, is, that mammals have not been able to migrate, whereas some plants, from their varied means of dispersal, have migrated across the vast and broken interspace.

So that we are reduced to consider whether the exceptions to continuity of range are so numerous and of so grave a nature, that we ought to give up the belief, rendered probable by general considerations, that each species has been produced within one area, and has migrated thence as far as it could.

If the existence of the same species at distant and isolated points of the earth's surface, can in many instances be explained on the view of each species having migrated from a single birthplace.

And as the plants and animals migrated southward, they will have become mingled in the one great region with the native American productions, and have had to compete with them.

But I do not doubt that some temperate productions entered and crossed even the lowlands of the tropics at the period when the cold was most intense, -- when arctic forms had migrated some twenty-five degrees of latitude from their native country and covered the land at the foot of the pyrenees.

The facts seem to me to indicate that peculiar and very distinct species have migrated in radiating lines from some common centre.

Waves of vegetation had migrated away from the equator, until tropical rain forest eventually covered all of Africa and South America, North America to what would become the Canadian border, China, Europe as far north as France, and much of Australia.

Most of the birds and the large herbivore herds had long gone, migrated south to warmer, easier climes, taking their dinning cries with them.

That vast, enduring family had emerged a few million years earlier in Asia, and had since migrated around the world.

And as they had migrated, so they had flourished, diversified, and changed.

Australia had migrated north until it rammed itself into southern Asia, and Africa had crashed into southern Europe.
