The Homo Sapien

What evidence shows the changing from the early hominids to the modern humans? Throughout the human evolution body parts like legs and harms have changed for the better. By the early hominids being biped, meaning they are able to stand and even walk on two feet, it helped them to be able to do more things like getting around more and help with their tool making and hunting. A lot of the fossils discovered were found in the Great Rift Valley in East Africa, which contained many different lakes and small rivers. For many years researchers have been finding new species. These species have been named Australopithicus, robust australopithecines , Orrorin tugenensis, Homo habilis, Homo erectus, neanderthal, and Homo sapiens. These early

In his On the Origin of Species, written in 1859, Charles Darwin clearly explained the gradual progression toward the speciation of organisms with his five main principles: variation, inheritance, competition, selection, and propagation. Darwin hesitated to publish his findings because he understood that his findings were based on the animal kingdom and on an evolutionary process that had to have spanned millennia. He specifically did not think that his discoveries were applicable to the evolution of human society. Contrary to Darwin’s preference, Herbert Spencer did exactly what Darwin hoped to avoid by publishing numerous works supporting his own, new thesis of “Social Darwinism,” which claimed that Darwin’s principles of evolution

One of the most astonishing things on earth is the human body. They consist of many organs that work together to maintain the person alive. The humans body composition is complex, but what was the origin? How did we become who we are today? These are the questions that intrigued me, and allowed me to understand how the human body evolved over the years. By the examination of our ancestors, and our body we will understand how we look today.

We often have misconceptions whether we share some DNA with common ancestors and we now have the ability to fully understand that we do. When people first meet, they often ask where we are from and respond with an ethnic background, but do not take the time to realize how we came to be. Not many think back to the time where modern humans truly became modern humans and see if we even shared DNA with them. Not many like to admit that they share DNA with those who were “clueless and lived in caves”. One of our common ancestor, Homo neanderthalensis, were found around 400,000 to 40,000 years ago in most of Europe and Southwest Asia (Smithsonian National Museum of Natural History, 2016). Upon discovery, scientists were able to use the combination

Most people have heard of the Neanderthal, but there is a disconnect in how people understand this ancestor or cousin to modern man. The history, anatomy, culture and genetics of Neanderthal Man shed light on the relationship between this species and our own. This essay considers the Neanderthal man in terms of its evolutionary history, anatomy, and culture, investigating the genetic relationship of this species to Homo sapiens sapiens, or modern man. The essay pays special attention to the evidence offered for the Neanderthal’s existence and evolution, ultimately concluding that very little is actually known, though a preponderance of evidence exists for ongoing research and analysis.

The news has a tendency of overstating what’s seen as facts. Television news requires high viewership and ratings and newspaper would want people to subscribe to it. For that to happen, news makes things more serious than what they really are, making the event more engaging than in reality. News also input various pictures

The destructive light of media we like to believe in unhealthy news more the worthy news. With news outlets, normally its only one or two decent things and the rest are sad events that occurred or will happen. The negative point on media is that the internet has people believing there isn’t a problem. They would rather listen to bad

According to the consensus view, the Neanderthals lived 250,000 to 30,000 years BP (Before the Present), they were very primitive, looked more like gorillas than men, led a short brutish life, and died on average at the age of forty-five. According to my research, they were built more powerfully than modern Humans. Their thicker tendons and ligaments, attached to heavier bones, gave them superior strength, and the capacity of leaping high to hunt large animals. One of their back muscles, that Humans have lost, added tremendous force and precision for throwing an object such as a lance, or for handling a sword. Their voluminous rib cage gave superior stamina during any effort. Their eyesight was much sharper than that of modern Humans'

Throughout time human species have evolved. It all started seven million years ago. Many different kinds of ancient humans have roamed Earth. The first species were discovered in Africa and later in Asia, Europe, Australia, and the Americas. Paleoanthropologists, geologists, anatomists, and paleoecologists determined when and where new species evolved by analyzing hominid fossils. They can also tell us how species lived and died, which other species they are related to, what was the climate like, and the plants and animals people relied on.

One fact that all anthropologists agree on is that H. Erectus evolved in Africa and during interglacial periods migrated to other parts of the world. What anthropologists cannot agree on is when H. Erectus became H. Sapiens. Paleoanthropologists know H. Erectus, H. Sapiens, and Neanderthals or Denisovans co-existed roughly 100,000 years ago during the Ice ages. Some species, not unlike Neanderthals or Denisovans, were able to adapt to the frigid temperatures of the Ice ages while others, not unlike H. Erectus, preferred inhabiting more tolerable temperatures. Yet, one group of hominids is able to tolerate both warm and cold temperatures and this group is known as H. Sapiens. The preferences of each species would explain why H. Erectus is mainly found in Africa (or places of an equivalent latitude), Neanderthals in Europe, Denisovans in North-Eastern Asia, and H. Sapiens in different geographical locations. So far, it has been established that these three different hominids existed together 100,000 years ago but what is commonly debated today is how each hominid species originated and more importantly how H. Sapiens originated.

In tracing the direct ancestors of Homo sapiens sapiens, the five consequent Hominins I would include in the timeline of human evolutions: Australopithecus afarensis and africanus, Homo habilis, Homo erectus, Archaic Homo sapiens, and Homo Neanderthal. In 3.6 million years ago, Australopithecus afarensis is considered the earliest hominins that are close relative to Homo. Afarensis had slender body built, but relatively larger than modern humans, but with smaller brains, and a prognathic face. In 1975, the discovery of Lucy commonly referred as “first family”, reveals evidence of bipedalism. In 3.3 million years ago, Australopithecus africanus is considered extinct classified species as hominin. Africanus remain

Homo sapiens, or “consciously thinking human”, evolved 25,000 years ago forming an unprecedented presence in the environment and the efficient exploitation of the environment. Physiological structural advantages aided the Homo sapiens in taking the upper hand over other species. A fundamental difference in the brain structure of the Homo sapiens was a well-developed frontal region where conscious and reflective thought takes place. Intelligence is the sharp edge of survival for these hominids because physically they are not endowed with great strength or natural means of defense which battle natural selection in the animal kingdom. Change in physiognomy such as upright walking posture with opposable thumbs freed the hands from the task of locomotion and was instead applied for the creation of higher sophisticated tools. Development of language allowed for communication enhancing cooperation and a sense of cohesion as well as paving the way for collective learning which is the drive for creating complexity. Homo sapiens used superior intelligence, sophisticated tools, and language to exploit the natural world more efficiently than any other species

From my understanding of how we human sapiens are living now, it is a lot easier than what it used to be 70 thousand years ago. I am not saying that it is easy for us but as a nation that is more civilized than how it was back then. We don’t have to worry much about food due to it being ready for us at the store that we can just go pick up but in some cases, some people can't afford to buy food and ended up in poverty. There are goods and bads about how we modern homo sapiens are living now and same goes for them living 70 thousand years ago.

Some of the information retrieved from the media may cause individuals to have a negative outlook. For example so individuals who constantly view violent news segments may believe the world is a violent place

Human evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable affinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a common ancestor. The subject of what makes humans what they are and their origin has been the exclusive purpose leading to many scientific studies globally (Coolidge & Wynn, 2011). Studies believe that Africa was the origin of evolution millions of years ago. Fossil remains have been discovered in different parts of Africa as well as other regions of the world. Different hominins have been discovered around the world in the last 1 million years. Thus, the different discoveries have led to comparisons between the various species of hominins to clarify on their similarities as well as differences. This essay seeks to explain whether they were distinctively different species or regional versions of the same species.
