Question

21 which evidence would most strongly support the theory that the americas were first populated by people migrating across a land bridge that connected northeast asia and north america?
american indians’ lack of immunity to many diseases endemic to afro - eurasia
architectural similarities between the pyramids of teotihuacan, mexico and giza, egypt
data showing a close genetic link between american indians and indigenous people of siberia
the discovery of pottery from ming china at a pre - columbian site in peru

Explanation:

To support the theory of migration across a land bridge between Northeast Asia (like Siberia) and North America, we analyze each option:

• The first option about disease immunity relates to post - migration contact, not the initial migration.
• The second option about architectural similarities between Teotihuacan and Giza is about different regions (Africa - Americas) and not related to the Asia - Americas land bridge migration.
• The third option: If there is a close genetic link between American Indians and Indigenous people of Siberia, it suggests a common ancestry, which would support the idea that people migrated from Northeast Asia (Siberia) to North America via the land bridge.
• The fourth option about Ming China pottery in Peru is related to later trade or contact, not the initial peopling via the land bridge.

Answer:

C. Data showing a close genetic link between American Indians and Indigenous people of Siberia
