Paternal Haplogroup Origins R-M343Your 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.
What do people with the surname Alonzo have in common?
Spoiler alert: it's complicated. People with the same last name are usually no more genetically similar than a randomly sampled group of people from the same population. That said, people with the same surname are more likely to have similar ancestries than randomly sampled individuals. The reason is the tendency of people with similar cultural or geographical backgrounds to preferentially mate with one another. That's why people who share a surname may be more likely to share traits and tendencies in common than people within the general population.
