This isn’t a surprise. Most people alive today are probably descended from many important historical figures. This is especially true for historical figures that are known to have many children, or whose children were known to have many children. Go back ten generations (about 250 years) and everyone has at most 1024 ancestors. Ten more generations and it’s over a million. A thousand years, a trillion ancestors, but at this point there’s definitely huge amounts of repeating. With the exception of bloodlines known to have died off, and isolated groups who stayed strictly separate from others for hundreds of years, most people alive today are likely descended from everyone who was alive on their continent of origin that long ago, and possibly even more depending on the extent of communication and relations with other groups.
