Due to the railroads, American settlers were able to travel west in larger numbers. How did this migration impact Indigenous People?
O Indigenous People's way of life changed because buffalo herds were destroyed for commercial markets.
O Indigenous People voluntarily went to reservations because they needed to find food and shelter.
O Indigenous People became cattle ranchers in order to survive a decrease in income.
O Indigenous People faced economic decline because they could no longer sell buffalo meat.

A) Indigenous People's way of life changed because buffalo herds were destroyed for commercial markets.

Explanation:

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
