Suppose you are an archaeologist trying to answer this question: When did the first people migrate to North America? Why might the answer to this question change over time? What do you think? Check all of the boxes that apply. Scientists might find new sites with human artifacts, thus providing new evidence. Scientist might develop new technology that helps them assign different ages to existing artifacts. Scientists might come up with new theories using existing evidence. Scientists might learn more about the conditions in the world in which prehistoric humans lived.

These statements apply:

Scientists might find new sites with human artifacts, thus providing new evidence.

If scientists find human artifacts in new places, such a finding would likely change archeological theories about the first migrations to North America.

Scientist might develop new technology that helps them assign different ages to existing artifacts.

If new technology is used to assess the time period of certain artefacts, and that technology determines that the time period is different, then what happens is that the time period itself to which archeological evidence was tied changes, meaning that the dates previously established have to be revised.

Scientists might come up with new theories using existing evidence.

If scientists can developed new sound theories using existing evidence, then it is likely that the dates previously set are modified.

superior technology and improved medical knowledge to foster imperialism. quinine enabled europeans

to survive tropical diseases and venture into the mosquito-infested interiors of africa and asia. the combination

of the steamboat and the telegraph enabled the western powers to increase their mobility and to quickly respond

to any situations that threatened their dominance. the rapid-fire machine gun also gave them a military advantage

and was in convincing africans and asians to accept western control. the following table summarizes the

causes of the new imperialism:
