The Timeline of Human Migrations

This is a timeline of the different points in history including the early human migrations, the Bronze Age, the Iron Age, the Portuguese colonization and the industrial times. I’m talking about the different points of history to know where we came from.

The Early human migrations

Early human migrations are the first migrations and expansion of ancient and modern humans across continents. It began 2 million years ago with the Out of Africa migration of Homo erectus. The climate change affected the migration by 21,000 yearlong wobble in the Earth’s axis meaning that sometimes Northern Africa and the Arabian Peninsula would get less sunshine but more rain creating greener, wetter landscapes, and more ways for human expansion. They extended rapidly along the coast to India, and reached Southeast Asia and Australia by 50,000 thousand years ago. A bit later after 50,000 thousand years ago, a next group appears and planned an inland hike from the tropics to go to the Middle East and Southern Central Asia. They were poised to inhabit the northern latitudes of Asia, Europe and beyond. Around 20,000 years ago a small group of Asian hunters headed into storm, going in the East Asian Arctic throughout the Last Glacial Maximum. In this point the great ice sheets covering the far north had sucked a lot of Earth’s humidity in their massive stretches of ice. It had dropped sea levels by more than 91 meters. This showed a bridge that connected Asia to America. The hunters crossed it, by 15,000 years ago they had entered the land below the ice and in 1,000 years they had made it all the way to the tip of South America. Some maybe even made it by sea.

The Bronze Age

The Bronze Age is an ancient period described by the use of bronze. An ancient civilization is defined to be in the bronze by producing bronze from producing bronze by smelting its own copper and mixing with tin, arsenic, or other metals, or by trading for bronze from production areas somewhere else. Bronze is harder and tougher than other metals obtainable at the time, letting the Bronze Age civilizations to gain a lead. The beginning of the period is sometimes called the Chalcolithic (Copper-Stone) Age, referring to early use of pure copper along with its previous toolmaking material, stone. It was rare at first, copper was originally used only for small or valuable objects. Its use was known in eastern Anatolia by 6500 BC, and it soon became common. Few tools are made in the beginning, but by 1200 BC bronze has replaced all stone tools. When bronze proved better than copper, it was abandoned as the metal choice for tools. Bronze became important because it was strong.

The Iron Age

The Iron Age is the period after the Bronze Age. Its production took place in Anatolia at least 1200 BC. Most of Europe, Asia and Africa reached the Iron Age by 500 BC. Iron is easy to find, but hard to make into tools. It melts at a higher temperature than bronze. When blacksmiths learned how to make iron tools, could make many of them. With better tools, they could do more. Some people developed coins to help buy and sell their crops and their iron tools.

Portuguese Colonization

The Portuguese were searching for a route to Asia by sailing around Africa. They were under control of Prince Henry the Navigator and discovered Angola, Cape Verde, Guinea-Bissau, Mozambique Sao Tome and Principe searching in the 1500s. The Portuguese explored the land by boat.

The Industrial Age

The Industrial Age is a period of history that includes the changes in economic and social organization. It began around 1760 in Britain and later in other countries. It was mainly the replacement of hand tools with powered machines such as the steam engine and by the concentration of business in large creations. Henry Ford was a certified machinist that made the first car and founded the company called Ford. Firstly, he worked on his first engine. When his design was right, he began to work on his first Quadricyle, a car liked creation. It was running by a small engine and steered by a lever.
