Answer:
We have changed in regards to our social attitudes and beliefs, advanced our technology, and we've changed how our societies are run and organized.
Explanation:
Our social attitudes and beliefs have changed because we've become more tolerant and less ignorant towards other races and cultures different than our own. Minorities and women have gained more rights, and we've become less strict and conservative about how we live our lives.
Our technology has advanced because we have gone from hand made stone tools to cars, planes, computers, and more. In the span of a hundred years or less, we went to the moon, can travel far and wide with ease, and can spread news instantly across the globe.
We've changed how we run our societies and organize ourselves because our forms of government have evolved. We've gone from lawlessness and fighting over territories to monarchies, democracies and dictatorships. When certain forms of government have failed, such as dictatorships, we stepped in to help each other to fix them. Normally switching to a democracy.
Hope that helps! :)
