What is Y chromosome analysis and how should we use the findings?
|The Y chromosome is the male counterpart to mtDNA in that it is inherited from father to son without recombination with the X chromosome. In other words, the male-specific part of the Y chromosome contains a record of the mutational events that occurred on all previous ancestral Y chromosomes and tracks a single lineage consisting of the father, the paternal grandfather, one paternal great-grandfather, etc.(quote)|
|What I want to say by this is that our civilization has made this kind of analysis possible. If you blame someone picking any
historical record of some time ago, no matter when it was, 1200, 500, or 50 years ago, we will have to go all the way back to
38,000 years or 60,000 years ago when human being left Africa. The similar research is also available about Anglo-Saxon.
Why don’t we use these findings of our civilization now, meaning to understand the genetic history of lineage
conflicts, be fed up and freeze them?

|Neural Darwinism and altruism:
Altruism soon shifts from reproductive necessity to to moral imperative. Over time there is a steady expansion of responsibility, marked, however, by many fits, starts, and retreats. From the biological responsibility of the family, the right to entitlement expands to loosely linked families, to common language speakers, to fellow religionists, to citizens, to servants, and now, slowly beyond the nation-state to all the world’s peoples....

|Even with my strong belief in science, there is one theory I feel reluctant to accept; value system which I think is a mainstream theory to explain brain consciousness; “survive at any cost” called Neural Darwinism and many believe that human being is programmed this way. One of Nobel laureates who support this theory says that altruism is not the biological and genetic nature of human being.Is this true? (comment #79)|
