Your paternal lineage may be linked to the Yayoi

Haplogroup O1b2a, a branch of haplogroup O, is closely related to several haplogroups that are commonly found in Japan. Haplogroup O is closely associated with Kyushu, Japan's third largest island, and makes up over half of all men in Japan. Although haplogroup O is prevalent in Japan, it likely only entered Japan during the Yayoi expansion about 2,300 years ago. During the Yayoi expansion, people entering from the Korean Peninsula brought wet rice agriculture, weaving technology, and metalworking technology to Japan. The Yayoi expansion began on the island of Kyushu, where haplogroup O is very common today. It is possible that some of the early members of O1-F3356 were involved in this major shift, which quickly and dramatically altered Japanese culture.

Your maternal lineage may be linked to the Han

Members of haplogroups B4 and B5 are quite frequent in both northern and southern Han Chinese populations. The Han people, who all share the same language and similar cultural practices, are the largest ethnic group in the world, with about 1.2 billion people. Historical evidence shows that Han people are descendants of the ancient Huaxia tribes that come from northern China, centered in Zhongyuan, China's Central Plain. The spread of Han people, language and culture from northern to southern China only occurred in the last 2,000 years, and was likely driven by warfare and famine in the north.

What do people with the surname Seo 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.
