yes, that's right, and read about Babel in Genesis, adaptation occurred because of geographical locations, incest became a problem after the flood, that is why God prohibited it 3500 years ago
adaptation is NOT evolution
Adam and Eve were born with pigmitation
Noah's Sons children gathered in Babel
Gen 10:32 These were the families of the sons of Noah, according to their generations, in their nations; and from these the nations were divided on the earth after the flood.
Gen 11:1 Now the whole earth had one language and one speech.
Gen 11:2 And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar, and they dwelt there.
Gen 11:3 Then they said to one another, "Come, let us make bricks and bake them thoroughly." They had brick for stone, and they had asphalt for mortar.
Gen 11:4 And they said, "Come, let us build ourselves a city, and a tower whose top is in the heavens; let us make a name for ourselves, lest we be scattered abroad over the face of the whole earth."
Gen 11:5 But the LORD came down to see the city and the tower which the sons of men had built.
Gen 11:6 And the LORD said, "Indeed the people are one and they all have one language, and this is what they begin to do; now nothing that they propose to do will be withheld from them.
Gen 11:7 Come, let Us go down and there confuse their language, that they may not understand one another's speech."
Gen 11:8 So the LORD scattered them abroad from there over the face of all the earth, and they ceased building the city.
Gen 11:9 Therefore its name is called Babel, because there the LORD confused the language of all the earth; and from there the LORD scattered them abroad over the face of all the earth.
