Supporting a controversial view of how humans might have populated the Western Hemisphere, geneticists have found that groups from Asia traveled over the Bering Strait into North America in at least three separate migrations beginning more than 15,000 years ago - not in a single wave, as has been widely thought. "We have various lines of evidence that there was more than one migration," said Dr. Andres Ruiz-Linares, a professor of human genetics at University College London and senior author of a report on the findings that was published Wednesday by the journal Nature.

CUATRO MILPAS, MEXICO - In this hardscrabble farming village, an American teenager like Luis Martinez was bound to stand out. Raised on Little Caesars pizzas and Big Gulps, Luis, 13, was portly. The village kids, subsisting on bowls of chicken broth, were all bones and elbows. Luis wore Air Jordan high-tops. The kids wore sandals made of rubber tires.

Climbing temperatures are expected to raise sea levels and increase droughts, floods, heat waves and wildfires. Now, scientists are predicting another consequence of climate change: mass migration to the United States. Between 1.4 million and 6.7 million Mexicans could migrate to the U.S. by 2080 as climate change reduces crop yields and agricultural production in Mexico, according to a study published online this week in the Proceedings of the National Academy of Sciences.

The Malagasy people of Madagascar carry the genes from ancestors in nearby East Africa and distant Borneo, suggesting a big migration from Asia to Africa 2,000 years ago, British researchers reported Tuesday. The genetic study, published in the current issue of the American Journal of Human Genetics, supports the puzzling finding that the Malagasy language more closely resembles Indonesian dialects than East African tongues.

"Jobs Migrating Overseas, but It's a Two-Way Street" (James Flanigan, July 20) states, "The net number of jobs going overseas is overblown. The most thoughtful assessment is that 80,000 jobs will go overseas this year and 120,000 next year, says John McCarthy, a director of Forrester Research in Cambridge, Mass." If outsourcing continues to grow at that rate (50%) 9,064,000 jobs will be shipped overseas in the next 10 years. The column also mentions Oracle Corp. as a positive example of how Americans need to accept the migration of our economy to Third World status.

Migrating birds use the Earth's magnetic fields to navigate, but sunsets also play a crucial role, according to new research reported in the journal Science. Biologist Martin Wikelski of Princeton University and his colleagues studied thrushes flying north, placing them in a magnetic field that disrupted their internal compass. When the birds were released, they flew west instead of north. But the next day, after a sunset, they started flying in the right direction again.
