Answer:
laws that restricted where African Americans could live
Explanation:
Jonathan Worth was a governor of North Carolina for two consecutive terms, until he was removed from office by military decree.
Jonathan Worth was a Democrat and, like his fellow party members, supported the black population to live in a state of semi-freedom, where they did not have all their civil rights and duties guaranteed. In addition, he supported the establishment of laws that restricted where African Americans could live, forbade them to vote, testify in court, in addition, he was against the implementation of the 14th amendment that upheld equality rights for African Americans.
We can only theorize about how the life would be if the humans appeared earlier on the Earth, as we can not create a perfect and accurate picture of how would the things have been.
If the humans were developing in the same manner as we had, than we can say that the humans would have been much more advanced. The technology would have much better, probably missions to the other planets would have been regular. The population would probably be higher, with most of the population being concentrated in highly advanced megalopolises.
The environment though would probably be in a terrible condition, with enormous loss in biodiversity across the globe, decline in the forests, and much emptier (with life) oceans. On the other hand, there's every chance that with the more advanced technology multiple animals and plants would have been resurrected, even some extinct very long time ago.
It was the white people vs the black people. That was the main reason
