课程名称：世界历史 - 早期人类的故事 课程概述： 该课程以“从时间的开始”为主题，专注于人类演化的过程。课程详细讨论了人类的起源中心、早期人类获取食物和住所的方式，以及他们如何制作工具。早期人类的交流方式主要是通过语言和艺术。专家教师为课程准备的笔记涵盖了各个方面，力求全面。 内容包括： - 人类历史的理解需要考古发现，这些包括人类化石、石器工具以及洞穴壁画等，每一个发现都有其独特的历史背景。 - 人类化石是指很久以前的人类遗留的遗骸或印痕，它们通常嵌入岩石中，从而得以保存数百万年。 - 早期人类制作和使用的石器工具在非洲和欧洲各地都有发现，包括卵石、锋利的石头和石刀等，用于早期人类的多种需求。 - 在欧洲和非洲洞穴中发现的壁画，帮助我们更好地理解早期人类的历史。 课程还讲述了尼安德特人头骨的发现过程，并追踪其历史的发展。1856年，德国杜塞尔多夫附近的尼安德谷，工人在采石时发现了一个头骨和一些骨骼碎片，这些化石后被认为不属于现代人类，最终被命名为尼安德特人。 另外，课程还介绍了人类演化的进程：大约在3600万到2400万年前，灵长类动物在亚洲和非洲出现；2400万到560万年前，灵长类动物中出现了一种称为人猿的亚群；最后，在560万到180万年前，人类从人猿中进化而来，展现出共同特征与重要差异。 总之，该课程为学习早期人类历史提供了深入而全面的视角，适合对历史与人类演化感兴趣的学习者。
FROM THE BEGINNING OF TIME is Lesson 1 in CBSE Class 11 History Book. The Story of Human Evolution is discussed in detail with THE POSITIVE FEEDBACK MECHANISM. The Centre of Human Origin. How the early human get their food, shelter and how did they make their tools? The mode of communication of Early humans was language and art also. The notes are prepared by the expert teachers and we have tried our best to include each and everything in making the notes.Sources to understand early human historyDiscoveries of human fossils, stone tools, and cave paintings help us to understand early human history. Each of these discoveries has a history of its own.Fossils are the remains or impressions of a very old human which have turned into stone. These are often embedded in rock and are thus preserved for millions of years.Stone tools made and used by early humans are available in various parts of Africa and Europe. Stone tools such as pebbles, sharp stones, stone blades, etc were used for various purposes in early human life.Paintings found on the walls of the caves in Europe and Africa are helping us to understand early human history.Most scholars refused to accept that these objects were the remains of early humans. They did not believe in the ability of early humans to make stone tools or paint. Because according to the Old Testament of the Bible, the human origin was an act of Creation by God. After a few years, the true significance of these finds was realized.How was Neanderthal man`s skull discovered?August 1856, workmen who were quarrying for limestone in the Neander valley a gorge near the German city of Dusseldorf, found a skull and some skeletal fragments.These were handed over to Carl Fuhlrott, a local schoolmaster and natural historian, who realized that they did not belong to a modern human.He then made a plaster cast of the skull and sent it to Herman Schaaffhausen, a professor of anatomy at Bonn University. The following year they jointly published a paper, claiming that this skull represented a form of human that was extinct.At that time, scholars did not accept this view and instead declared that the skull belonged to a person of more recent times. But later they accepted it and named as Neanderthal man.The Story of Human EvolutionBetween 36 million years and 24 million years primates, a category of mammals emerged in Asia and Africa. Primates are a subgroup of a larger group of mammals. They include monkeys, apes, and humans. They have body hair, a relatively long gestation period following birth, mammary glands, different types of teeth, and the ability to maintain a constant body temperature.Between 24 MYA and 5.6 MYA, there emerged a subgroup amongst primates, called hominoids. Hominoids are different from monkeys in a number of ways. They have a larger body and do not have a tail. Besides, there is a longer period of infant development and dependency amongst hominoids.Between 5.6 MYA and 1.8 MYA hominids have evolved from hominoids and share certain common features and have major differences as well.
