Reading

Reading from the textbook provided a different perspective on the worlds history. I find it interesting and useful how the author of the book decided to create a calendar of the worlds history. It helps us to get a feel on a time system that we are used to. The part that really interested me was reading that the whole history of the United States of America would be the last second of the last day in December. I find this interesting because as I look back at the history of our country, so much has happened. To know that all that time amounts to only a second on the calendar amazes me. I cant even imagine how much has gone on from the beginning of the world till now. Humans have inhabited the earth for about 250,000 years now and its crazy to think how much the homo sapien has changed the world. From the stone age to the agricultural revolution to the modern industrial era, great advances in humankind were created in such a little span of time because we are able to make comparisons and connections with various things and people. The question that comes to my mind is, "what made these early creatures like the homo habilis and the homo erectus want to travel and expand?" I think this because why would anyone want to keep migrating to an unknown world? None of them knew what was out there. They didnt know what they would be facing, yet they still went. It makes sense on how their brains and body structure started to change as they moved to different places. They obviously changed because of the new experiences and challenged that they faced.
