Homo sapiens

Human evolution is the long process of change in which humankind originated from apes. Before Charles Darwin, Carolus Linnaeus, chose the word,”homo,” which is Latin for human, in his classification system. During this time, along with Linnaeus, other scientists considered apes to be close relatives to humans due to their anatomical similarities. In the 1960s and 70s, African researchers found fossils of australopithecines, an extinct creature related to humankind in Africa. Later more fossils…

ardipithecus boisei is 18.5, homo erectus is 35.71, homo habilis is 33.6, homo heidelbergensis is 26.1, homo neanderthalensis is 25.5, homo sapiens is 36.77, and sahelanthropus tchadensis is 18.5. The fact is if the opisthion index is less than 15, then that organism walks with two feet. We can conclude that all the organisms are bipedalism…

Creationism is the belief that the universe along with everything in it was created by acts of divine creation. A good example would be how the Christians believe that God is the creator of all things. Evolution is the process of different species developing and diversifying over a period of time to adapt to their environment. A good example would be us. According to scientists we have ancestors that trace back to six million-years-ago to a group called the Ardipithecus group which is our…

Homo ergaster, meaning ‘workman’, lived in eastern and southern Africa around 1.5 million years ago. The ergaster had a good run for about 500,000 years, until vanishing from fossil records 1.3 million years ago. Homo ergaster was discovered in 1949 somewhere in southern Africa by prominent South African hominin paleontologist, John T. Robinson. Researchers have argued back and forth on the the idea that Home ergaster is a valid taxon due to the similarities between ergaster and erectus. Some…

more about our past ancestors with the intent to reveal more about ourselves and to define what innately makes us human. Although many skeletons and species of Homo have been identified, we have not yet discovered our last common ancestor, and this has been a hot topic of debate. The genus Homo is bookended by Australopithecus afarensis and Homo erectus, the former more ape than human, while the latter was responsible for making stone tools. However as National Geographic claims, “there is still…

Looking into the past research, I have always wondered where is the origin of humanity. Many have attempted to answer this simple question, but to be honest, it is more complex than a simple answer. As researchers began to dig, new evidence may suggest that Africa could be the birthplace of humanity by means of archaeological finds, use of ancient tool, and development of agriculture. Each of those giving clear cut evidence that humanity came from the depth of Africa, and populated the world.…

Before Homo sapiens roamed the earth, flora, fauna, and the species known as Homo erectus, all coexisted. Homo erectus populated Africa, thriving amongst predators, the changing environment, and evolving characteristics of their species. However, certain environmental conditions that were impacting H. erectus, at the time, led to their departure from Africa to Eurasia, where they paved the way for future species and the colonization of the world. This journey of Homo erectus out of Africa and…

There are many definitions of the word story, but one definition in particular fits the topic of human origins perfectly; a narration of the events in the life of a person or the existence of a thing, or such events as a subject for narration. The story of human origin and the creation of human nature is a difficult story to tell, created by miniscule pieces of evidence and guesswork through paleoanthropology, and advances in the ability to look at and study DNA. Exactly where we came from and…

Stop 1: Chimpanzee, Modern Human, and Neandertal Skeleton 1. The modern human skeleton is much larger in size compared to the chimpanzee and hominid skeleton. The Chimpanzee had longer arms, much narrower rib cage and smaller skull compared to both ancient hominid and human. On the other hand, the hominid had robust bone joints, allowing more flexibility. The skeleton structure of chimpanzee indicates that they moved by using four limbs while both human and hominid walked upright. 2. The…

ones are the influence of food on inter-birth interval, the avoidance of starvation by Homo sapiens ancestors, our ancestors’ loss of body hair, and the influence of Darwinian selection for social tolerance and cooperation. Wrangham’s hypothesis provides answers for these and other questions throughout his book. Wrangham opens his book pondering a deep question: what made us human? He then states that the Homo genus “stemmed from the control of fire and the advent…
