These were the first beings that we’d identify as ‘hominids’ – a term which covers a wide range of human-like creatures.\n\nHomo habilis means ‘handy man’ in Latin. This is because these early hominids were the first of our ancestors to use tools, known as Oldowan tools.","1ba16cb3-6dd2-405a-915f-dd124be97ee6",[621],{"id":589,"data":622,"type":67,"version":24,"maxContentLevel":34},{"type":67,"reviewType":34,"spacingBehaviour":24,"collapsingSiblings":623,"multiChoiceQuestion":624,"multiChoiceCorrect":626,"multiChoiceIncorrect":627,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6,"matchPairsQuestion":628,"matchPairsPairs":629},[586,590,591],[625],"Who used Oldowan tools?",[597],[595,598,599],[81],[630],{"left":597,"right":631,"direction":34},"Used Oldowan tools",{"id":633,"data":634,"type":24,"maxContentLevel":34,"version":34,"reviews":637},"fc30ccb0-1f8b-4cec-8cf4-e056c8792100",{"type":24,"markdownContent":635,"audioMediaId":636},"From the Homo habilis there developed more complex hominids.

Homo erectus and Homo ergaster also crafted more intricate tools known as Acheulian tools, which included the earliest axes.\n\n![Graph](image://903a2ec6-76a1-4365-a7cc-5e7a89233c55 \"Acheulean Tools.

Around 3100 BCE, in ancient Sumer, traders started to use the first written inscriptions. Initially, this culture relied on tokens for simple bookkeeping; however, they soon moved to logographic writing on clay tablets.\n\n![Graph](image://3d54bdb3-d57c-4c92-b8e1-51614a89bf12 \"Mesopotamian counting tokens.

Remember the first Agricultural Revolution, about 12,000 years previous to this? Well, this was arguably just as seismic. Several innovative practices massively increased crop yields, which enabled the Industrial Revolution by feeding the workers and freeing up labour.\n\nOne of these innovations was the Norfolk four-course crop rotation system. By cyclically planting wheat, barley, turnips, and clover, farmers not only kept the soil fertile without leaving it fallow but also provided year-round fodder for livestock and enriched the soil with nitrogen, thanks to the clover.\n\nBeyond just crop rotation, the era was marked by several other agricultural advancements. Jethro Tull's introduction of the seed drill in 1701 revolutionized planting with a mechanism that sowed seeds at consistent depths and in straight rows, enhancing germination and substantially increasing crop yields.\n\n![Graph](image://0d461a73-44ce-482c-b274-e06d7c58fac3 \"Jethro Tull's seed drill.

Simultaneously, improvements in plow design, especially the iron moldboard plow, streamlined the cultivation process. These robust plows cut deeper into the soil with fewer animals, speeding up preparation time for planting.","ee172652-ee86-40f9-877b-89715dc789ab",[1749,1760],{"id":1729,"data":1750,"type":67,"version":24,"maxContentLevel":34},{"type":67,"reviewType":34,"spacingBehaviour":24,"collapsingSiblings":1751,"multiChoiceQuestion":1752,"multiChoiceCorrect":1754,"multiChoiceIncorrect":1755,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6,"matchPairsQuestion":1756,"matchPairsPairs":1757},[1726,1730,1731],[1753],"Who introduced the seed drill?",[1736],[1734,1737,1738],[81],[1758],{"left":1736,"right":1759,"direction":34},"Introduced the seed drill",{"id":1761,"data":1762,"type":67,"version":24,"maxContentLevel":34},"16e65077-e6e2-456e-a8be-fe5be6ab497a",{"type":67,"reviewType":24,"spacingBehaviour":24,"activeRecallQuestion":1763,"activeRecallAnswers":1765},[1764],"What crop rotation method was introduced during the Second Agricultural Revolution?",[1766],"Norfolk four-course crop rotation",{"id":1768,"data":1769,"type":24,"maxContentLevel":34,"version":25,"reviews":1772},"76b52369-3523-4327-a9ed-7448c529399a",{"type":24,"markdownContent":1770,"audioMediaId":1771},"Another major innovation of the Industrial Revolution was the introduction of steam power.

This conference, attended by European powers and the United States, regulated European colonization and trade in Africa during the New Imperialism period. The conference sparked a hurried and often brutal rush for territory, disregarding the ethnic and cultural lines that had defined the African continent for centuries.\n\n![Graph](image://99b2365e-9d38-4e2e-b1ec-3bfb43d9bf44 \"World Empires in 1898.

Following the Spanish-American War in 1898, the U.S. acquired territories such as Puerto Rico, Guam, and the Philippines, marking its emergence as a colonial power. The doctrine of Manifest Destiny and later the Monroe Doctrine influenced U.S. policy, asserting regional dominance in the Americas and opposing European colonialism.\n\nAs the world moved into the early 20th century, these great global powers had reached a point of great tension.
