One way i think technology changed the world was boats it helped transportation and evolved the early humans. It taut them how to fish and survive off the water because it is one of the most abundant resource on earth after that it kept growing and eventually into an economy. The way those boats changed were the materials used the shape the height and other things that helped boats become what they were today. The first boat ever built was a hollowed out log. It was very unstable because it very skinny and long and also it didn’t perform well on the water because the bow was just flat no curves no nothing so it would push a lot of water thus making it very slow.
