For African Americans, the one-drop rule was a significant factor in ethnic solidarity. African Americans generally shared a common cause in society regardless of their multiracial admixture, or social/economic stratification. Additionally, African Americans found it, near, impossible to learn about their Indigenous American heritage as many family elders withheld pertinent genealogical information. Tracing the genealogy of African Americans can be a very difficult process, especially for descendants of Indigenous Americans, because African Americans who were slaves were forbidden to learn to read and write, and a majority of Indigenous Americans neither spoke English, nor read or wrote it.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was the one-drop rule not a significant factor for?
Ah, so.. unanswerable

Many groups continued their hunter-gatherer ways of life, although their numbers have continually declined, partly as a result of pressure from growing agricultural and pastoral communities. Many of them reside in the developing world, either in arid regions or tropical forests. Areas that were formerly available to hunter-gatherers wereand continue to beencroached upon by the settlements of agriculturalists. In the resulting competition for land use, hunter-gatherer societies either adopted these practices or moved to other areas. In addition, Jared Diamond has blamed a decline in the availability of wild foods, particularly animal resources. In North and South America, for example, most large mammal species had gone extinct by the end of the Pleistoceneaccording to Diamond, because of overexploitation by humans, although the overkill hypothesis he advocates is strongly contested.[by whom?]

Ah, so.. settlements of agriculturalists

In certain cases compound words and set phrases may be contracted into single characters. Some of these can be considered logograms, where characters represent whole words rather than syllable-morphemes, though these are generally instead considered ligatures or abbreviations (similar to scribal abbreviations, such as & for "et"), and as non-standard. These do see use, particularly in handwriting or decoration, but also in some cases in print. In Chinese, these ligatures are called hewen (), heshu () or hetizi (), and in the special case of combining two characters, these are known as "two-syllable Chinese characters" (, ).
