How did the creation of the nations and their languages evolve?
Genesis 11:1-9 "And the whole earth was of one language, and of
one speech. And it came to pass, as they (Humans) journeyed from the east,
that they found a plain in the land of Shinar; and they dwelt there. And
they said one to another, Go to, let us make brick, and burn them throughly.
And they had brick for stone, and slime had they for morter. And they said,
Go to, let us build us a city and a tower, whose top may reach unto heaven;
and let us make us a name, lest we be scattered abroad upon the face of the
whole earth. And the LORD came down to see the city and the tower, which the
children of men builded. And the LORD said, Behold, the people is one, and
they have all one language; and this they begin to do: and now nothing will
be restrained from them, which they have imagined to do. Go to, let us go
down, and there confound their language, that they may not understand
one another's speech. So the LORD scattered them abroad from thence upon
the face of all the earth: and they left off to build the city.
Therefore is the name of it called Babel; because the LORD did there
confound the language of all the earth: and from thence did the LORD scatter
them abroad upon the face of all the earth."
The Book of Jubilees 10:22-26 "And the Lord our God said unto
us: Behold, they are one people, and (this) they begin to do, and now
nothing will be withholden from them. Go to, let us go down and confound
their language, that they may not understand one another's speech, and they
may be dispersed into cities and nations, and one purpose will no longer
abide with them till the day of judgment.' And the Lord descended, and we
descended with him to see the city and the tower which the children of men
had built. And he confounded their language, and they no longer understood
one another's speech, and they ceased then to build the city and the tower.
For this reason the whole land of Shinar is called Babel, because the Lord
did there confound all the language of the children of men, and from thence
they were dispersed into their cities, each according to his language and
his nation. And the Lord sent a mighty wind against the tower and overthrew
it upon the earth, and behold it was between Asshur and Babylon in the land
of Shinar, and they called its name 'Overthrow'."
As for the differences in appearance between nations, though scripture does
not say so, it would make sense that the Lord also changed their appearance to
further discourage there learning each others new language and staying together as one nation.
Yet in the future he will restore the earth to one language again.
Zephaniah 3:8-9 "Therefore wait ye upon me, saith the LORD,
until the day that I rise up to the prey: for my determination is to gather
the nations, that I may assemble the kingdoms, to pour upon them mine
indignation, even all my fierce anger: for all the earth shall be devoured
with the fire of my jealousy. For then will I turn to the people a pure
language, that they may all call upon the name of the LORD, to serve him with
