Profound Implications of an Environment of Human Origin

March 15, 2008.

In its February 21, 2008, issue, the scientific journal nature reported a study on genotype, haplotype, and copy-number variation in worldwide human populations. The study is reportedly based on a worldwide sample of 29 populations, 485 individuals, and five geographic regions of the world, namely, Africa, Eurasia, East Asia, Oceania, and America. The study supports the theory that humanity originated in Africa and spread to the other parts of the world.

The study also suggests that the geographic distance is a primary determinant of human genetic differentiation and draws parallels between linear increase in genetic distance and geographic distance from East Africa.

The Origin and Evolution of Languages

September 4, 2007.

Humanity has explored the vastness of the universe, the deep oceans, the microstructure of atoms, human consciousness, and so on. While the efforts made so far in these explorations are tremendous, even more efforts may be necessary to continue the explorations to fully understand nature.

Language has been the means of communication of humanity to better understand itself and nature. The history of origin and evolution of languages is another vast area that has not been fully explored. Attempts have been made in the past to understand the origin of languages. However, it doesn’t seem that any conclusion has been reached about it.
