This Thursday, the swallows formally make their storied return to San Juan Capistrano. But how do they and all the other migrating birds find their way thousands of miles to their winter and summer grounds? Scientists have found they do it much the way man has historically navigated around the world: the position of the sun and stars and familiar landmarks. They also take note of distinctive smells and the Earth's magnetic field.

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.

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.

Frank del Olmo likens the northward migration of Mexicans to the American vision of its Manifest Destiny back in 1845 (Commentary, May 20). He invites dialogue between the two countries and cautions against confusing the issues with myths. On this I agree. In 1845 the territory in question was sparsely settled, and our adventurous predecessors were living in the final stages of the Age of Exploration--their actions should be judged in the context of that time. Overpopulation and environmental degradation, the most important issues of today, were unheard of 150 years ago--the birthrate of Mexicans now crossing the border is notoriously high.

"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.

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.
