Similarities among Native American social structures included community-based governance, emphasis on kinship ties, and respect for nature. Differences could be seen in societal organization (e.g. matrilineal vs. patrilineal), economic systems, and social roles based on region or culture.
Vestigial structures are anatomical features that have lost their original function in an organism but are still present. These structures often have similarities to functional structures in related organisms, suggesting a shared evolutionary history. By studying these vestigial structures, scientists can infer how organisms have changed over time through the process of evolution.
Homo sapiens have existed on Earth for approximately 300,000 years.
eh... nobody really knows that, but i think that it was too hot and they existed... O_o
Which theory states that Homo sapiens began in a single geographical area and spread out from there
Humans have existed for only about 0.2% of Earth's history, which is approximately 200,000 years out of Earth's 4.5 billion-year history. This indicates that humans are a relatively recent addition to the planet.

Major cultural differences are designated geographically, such as: Southeastern, Plains, Northeastern, and Coastal. (There ARE more)

Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.
Old ones are old, and new ones are 13.

American fever never really existed, it's just the title of a book about romance
Marco polo was a famous man he went traveling to china and ended up the king liking him so If not existed china and America wouldn't have shared differences
