Paternal Haplogroup Origins J-M304Your maternal lineage may be linked to some of the first Americans
Though the Ice Age was beginning to retreat when your A2 ancestors first entered North America, there were still massive barriers blocking their way. Glaciers and inhospitable climate covered much of the continent, blocking entry into the interior. Nonetheless, researchers have found evidence that a wave of American founders migrated over 13,000 kilometers to reach southern Chile in only 2,000 years, a blink of an eye in the story of human migration! Their highway to the south was the coast of the Pacific, stocked with fish, diverse marine mammals, and other valuable resources in the rich kelp forests of the upper latitudes and in the abundant fresh-water rivers near the equator. Because of this rapid movement south, the A2 haplogroup and its diverse branches are found throughout North and South America.
