Early Humans

Hello everyone,

I had fun researching about Early Humans. This information is all new to me so, again, I couldn't stop reading about it from several sources. I hope you also enjoy my findings below.

How far back does the human species go?  

Based on the illustration of recent fossil discoveries below, posted in January 11, 2019, contributor John Rafferty, human species goes back at least 4 million years ago. It demonstrates the evolution of Australopithecus and Hominin. Note that for nearly 1 million years, some members of Australopithecus and Homo overlapped in time with one another.

Was Australopithecus a species of human?

Australopithecus afarensis was a species of human capable of walking upright but only adapted to travel short distances on the ground. Studies done on hominid fossils found in sub-Sahara, Africa, shows evidence that they lived from 3.8 to 2.9 million years ago and hominid fossils have been found in sub-Sahara, Africa.

Was Homo Erectus a species of human?

Homo erectus was a species of human and taller than earlier human ancestors, writes Joseph Castro his livescience.com article: “Homo Erectus: Facts About the ‘Upright Man’.” He also states that “one of the most complete fossil skeletons ever found, a 1.5-million-year-old specimen of an adolescent make known as Turkana Boy (now known as Nariokotome Boy), may have grown up to 6 feet 1 inches.”

Compare Homo Erectus and Homo Sapiens in terms of the range and duration of their presence on the planet Earth.

Homo erectus:

Range: lived in Northern, Eastern, and Southern Africa; Western Asia (Dmanisi, Republic of Georgia); East Asia (China and Indonesia)

Duration: lived between about 1.89 million and 110,000 years ago.

Homo sapiens:

Range: evolved in Africa, now worldwide.

Duration: lived about 300,000 years ago to present.

Chapter 15: Scientific Revolution - "The Question of Origins: Why Europe?"

In Chapter 15 under the section “A New Way of Thinking: The Birth of Modern Science,” Strayer writes about “The Question of Origins: Why Europe?” “Science as Cultural Revolution.” “Science and Enlightenment.” For this post, I will focus on “The Question of Origins: Why Europe?” section, specifically responding to the comparison sidebar question: “Why did the Scientific Revolution occur in Europe rather than in China or the Islamic world” (p. 665)? The Scientific Revolution occurred in Europe rather than in China or the Islamic world because the western Europeans were ready to challenge the knowledge of others cultures in addition to having a well established legal system and autonomous universities which set them up for success. Several centuries after 1000 in China, the Confucianism culture was considered sophisticated and secular for that time period. It didn’t have as much religious dogma such as in Christianity and Islam and its technological accomplishments and economic growth wer...

Chapter 10: The worlds of Christendom, 500 - 1300

The definition of the word Christendom is the qualities and characteristics of a group of people or nations under a Christian set of morals and values, the Christian World. In history, Christendom refers to the Medieval and Renaissance idea of the central place of Christianity in the lives, nations, countries and states of individuals. Starting in the 4th century, the first Christian to become an emperor, Constantine I, used his power to rule the Roman empire to be a Christian State, causing a huge transformation into inhabitants’ lives. Whoever lived in that territory became part of the Christian World and were treated differently if decided to choose to not be part of it. “Christendom in its earlier stages came to refer to Christians united into one body. This unity was very significant because it was a unity of religion, but it was also a political unity creating powerful alliances.” The East and West were united in believing in one Holy Catholic and Apostolic Church. Christendom m...
