Question

Imagine that archaeologists found one of the following new pieces of evidence. Which one suggests that the theory that early humans came to the Americas from the Siberian region is not true? Archaeologists discovered signs of green landscapes and bodies of water in the regions where the early humans from Siberia first landed. Archaeologists discovered the presence of animals such as deer and rabbits before the arrival of early humans from Siberia. Archaeologists discovered barren land and infertile soil in the Americas before the arrival of early humans from Siberia. Archaeologists discovered evidence of travel between Asia and the Americas before the arrival of early humans from Siberia.

Answer 1

Archaeologists discovered evidence of travel between Asia and the Americas before the arrival of early humans from Siberia.

This statement suggests that the early humans do not come from the Siberian region but from Asia. In terms of human geography, history, culture and language, Siberia belongs to Russia. And Russia belongs to both Asia and Europe. Therefore, Siberia partly belongs to Asia and partly Europe. 
In reality, archaeologists did discover evidence of travel when the indigenous people of the Americas found distant genetic links common with people of Australia and Papua New Guinea with the small groups of people in the Amazonian region of South America. 

Having discovered signs of green landscapes and bodies of water is a useless evidence. It could have been there since the beginning of time. Those landscapes could be a natural landform. Therefore, this evidence would just to point to no one has ever inhabited Americas at this moment of time.

Deer and rabbits are present in Siberia, therefore, this would just point to this region evidently.

Barren lands and infertile soil would mean no one had ever settled in this place. If there was, it wouldn’t have been barren and infertile.
