I have studied one people, the Mundugumor of the Yuat River (now called the Biwat River), (7) who had developed a completely unworkable form of social organization which demanded that marriages be based on brother-sister exchange through five generations, with further complications-including a change of sex in each generation and the insistence on biological descent through brothers and sisters rather than through cousins.
Frequent killers had many more social relationships, through biological descent and marriage, than their victims did, suggesting that they targeted members of families in vulnerable situations, the researchers say.
For instance, he refers to "the four races-Indians (referring to Indigenous People), Europeans, Africans, Asians," "mixed race products," and the majority of African-Americans carrying "caucasoid as well as negroid genes." Further, "Asians" (whoever they are) are described by the author as "the fastest growing immigrant race, and African Americans are said to have a "biological identity," referring to their "biological descent," in contrast to their social identities.
It is scientifically reasonable to argue further (on the basis of DNA and other molecular evidence) that this "unfolding" occurred by biological descent from a common ancestor or limited group of ancestors; and finally, that natural selection by the environment for advantages conferred by genetic change is an important driving force in the process.
A good scientist can accept the evidence for the factuality of biological descent with variation from a common ancestor, while at the same time recognizing that no satisfactory theory of the process yet exists; it is a problem still to be solved.
The editors view race as a particular instance of the cultural definition of difference, in which individuals and groups use phenotypes or other marks of biological descent as referents for self-identification and social interaction.
If we situate him within the history of interaction between language theory and evolutionary thought in the nineteenth century, Huxley's writings on the Synoptic Problem look like an attempt to extend the parallels between the linguistic descent of language and the biological descent of species that intellectuals like August Schleicher (1821-68) and Charles Lyell (1797-1875) had already explored.
Analyzing genealogies as social charters rather than records of biological descent, Szonyi found that later editions tended to claim earlier and more prominent focal ancestors than their predecessors, revealing how lineages of humble origin tried to raise their social prestige and remove suspicion that they were descended from the lowstatus Dan or She aborigines who had initially populated Fujian.
In Christianity, however, the notion of family goes beyond that of biological descent. After all, Jesus was brought up by a stepfather, Joseph.
They pointed to a discrepancy between the Land Commissioners' favoured meaning of 'local descent group' (highlighting biological descent) and the principles (conception, life-history) by which the Belyuen claimants asserted their corporateness.
In the long run, these ideas will lead to a situation where our people are defined not by their relation to a living culture and community of people, but by their biological descent from an ancestor who was an Indian.
I have said that strict biological descent will not do for identification of posterity--either of the American people of 1787 or of ourselves.
