Why Did Homo Sapiens Survive?

According to my observation, even though Chimpanzee, and Gorilla are similar, they differ in many other ways when we go deeper in physical, and behavioral traits. However, both species also share the majority part of their DNA with Humans. Based on some reliable researches, some scientists realized that humans did not come from apes but instead shared common ancestors. As a matter of fact, humans and Primates are different, but share most of their genome, explaining why we found some similar patterns of behavior among humans, and

Every living thing on this planet has evolved from the same original specie. Having this information, could it not be concluded that all living things are, to some degree, related? Yes. To further explain, evolution is a theory that states that organisms have diversified or in other words, have changed into a more complex living thing. In the book Inherit The Wind, the townsfolk of the play disagree heavily with the theory of evolution. Common ancestry is the theory that states that all living things share a common ancestor or common descendent, which then ties into evolution. Speciation, both allopatric and parapatric, show evidence for common ancestry. Speciation is when new species arise due to an evolutionary process. There are multiple and observable accounts that are used to support the theory of common ancestry. Charles Darwin’s book, The Descent of Man And Selection in Relation to Sex, goes into specifics with these accounts with placental mammals. Placental mammals are mammals that nourish their embryos using the mother 's blood supply. Common Ancestry in placental mammals provides sufficient scientific evidence, such as the similarities in bone structures and genetic coding between animals, to support the theory of evolution.

All primates have a common ancestor, from millions of years ago. Go further back, and you will find a common ancestor for all mammals. Then a common ancestor for all vertebrates, then animals, then all life on earth. How closely two organisms are related can be deduced by looking for homologous structures, structures that look similar and have a similar function. This proves that the organisms descended from a common ancestor. Station 1 contained multiple vertebrate skeletons. They all had homologous structures, including a vertebral column and a rib cage. This shows that all vertebrates are related and come from a common ancestor with a

Embryological Evidence – similarities in early embryos can indicate they came from a common ancestor.

We have always differences and similarities Humans, Bonobos and chimps are close relatives in evolution. Chimps and bonobos can be considered as siblings and humans as their first cousin. We are so similar in many aspects that humans seem to have a very marginal

     The proponents of the separate species hypothesis believe that they had a common ancestor, but Neanderthals and modern humans were separate species. They argue that the Neanderthal line was a dead end, and that for some reason Homo sapiens thrived while they went extinct.

According to Diamond, Human ancestors moved to Eurasia around 1 to 2 million years ago and after human fossils began to resemble modern Homo sapiens and archaeologists called that period the Great Leap Forward. According to “Human Evolution and the Great Leap Forward - By Advocate De Waal Lubbe,” Scientists have estimated that humans branched off from their common ancestor, with chimpanzees, about 5-7 million years ago. Several species and subspecies of Homo evolved and are now extinct. These include Homo erectus, which inhabited Asia, and Homo Sapiens Neanderthalensis, which inhabited Europe. Archaic Homo sapiens evolved between 400,000 and 250,000 years ago.

Humankind has come a long way since the beginning of time and the beginning started in Africa. Anthropologists guess that we, Homo sapiens, come from other animals such as chimpanzees since they are our neighboring relative. Many other species arose in Africa as well and we all shared one thing and that was the ability to walk up on two legs. As time went on, our brains grew larger and we started migrating to other places such as Eurasia and started using tools. Ultimately, all of the species died out and we were the only ones left because of all the struggles we went through and the way we established settled societies.

Evidence indicates Neanderthals and Modern humans shared a common African ancestor and split on the evolutionary tree between 500,000 to 200,000 years ago. Neanderthals developed in the cold and harsh environment of Europe and western Asia. With a lot of water locked up in the polar ice caps, Africa was experiencing a severe drought. This arid and dry environment is where modern human’s direct ancestor was living. These people’s bodies were a lot taller and weaker (to allow heat to escape) in comparison to the Neanderthals. This severe drought placed modern humans on the brink of extinction. However, when a species is dying out only the most inventive and resourceful survive, this causes the fitness of the remaining population to increase. In Europe the Neanderthals toughness allowed them to be very successful. In Africa the modern humans developed something the Neanderthals did not have, imagination. In Africa to survive it was necessary to think ahead and this allowed them to make the final step in becoming modern humans. Every previous human ancestor had been limited to the confines of their environment, but these ancestors eventually made their way out of Africa, and their imaginative behavior is illustrated in the drawings they left behind for others to find. After they left Africa they could have very well come into contact with the Neanderthals. Neanderthals became

Although modern humans are of the only surviving ancestors in today's society other groups of early humans did used to walk where we walk. Which is why the greatest mystery and biggest question of human evolution is what happened to the Neanderthals. Neanderthals were the early group of humans who used to live in Europe and Asia thousands of years before Homo-Sapiens took over the world population. Many believe Neanderthals died off leaving nothing behind but scientist have provided that most humans have neanderthal DNA within them. Leading people to believe that our ancestors had interbred with Neanderthals. As Neanderthal DNA is 99.7 percent identical to modern human DNA providing that Neanderthal genes continue to lurk on within modern

Human beings are descended from apes. This may seem shocking to some, and many dismiss it as a myth in favor of other beliefs about how people and animals ended up on this planet. However, scientific evidence has traced our ancestry, and that of many other beings, all the way back to completely different creatures and even single celled organisms. This type of huge alteration of DNA over many years is known as evolution, and is responsible for the existence of all animals and other life forms currently in existence on Earth. Evolution is a real process that actually occurs to all living organisms over time, and the beliefs contradicting this process are false.

Homo sapiens became the only surviving species by not having changes in the basic human physique. They did not hunt or live in big groups because they could not supply for large amount of people . The population growth was slow, the women worked hard just like the men. There was significant equality between the sexes based on common economic contributions. They lived a civil but simple life which is why they survived for so long.

Our species, homo sapiens, was just one of the different human species that existed 100,000 years ago. Today, only our kind survives. How did homo sapiens make it to the 21st century without becoming extinct like the other human species? In Sapiens: A Brief History of Humankind, Israeli historian Yuval Noah Harari tells the history of the human race covering 70,000 years. Humankind went through several major revolutions which gave us the edge over the others. Harari introduces the exciting ideas about the binding power of stories and myths that unite millions of people around the world, and of biotechnology that create amortal cyborgs who will succeed our species. Leaders like Barack Obama, Bill Gates and Mark Zuckerberg recommended this international

Human evolution is the gradual process in which people, or Homo sapiens, originated from apelike ancestors. Scientific evidence, particularly in the form of fossils and secondary remains, show that the physical and behavioral traits shared by all people evolved over a period of approximately six million years. Humans are primates. Both genetic and physical similarities show that humans and the great apes (large apes) of Africa, chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas share a common ancestor that lived between 8 and 6 million years ago. The volume of fossils found in Africa suggests that most evolution occurred there and is likely the place of origin for early humans. This brings to fruition the “out of Africa” theory, also called the “single-origin hypothesis.”

There has been a great deal of heated debate for the last few decades about where modern Homo sapiens originated. From the battle grounds, two main theories emerged. One theory, labeled “Out-of-Africa” or “population replacement” explains that all modern Homo sapiens evolved from a common Homo erectus ancestor in Africa 100,000 years ago. The species began to spread and replace all other archaic human-like populations around 35,000 to 89,000 years ago. The rivaling opinion, entitled the “regional continuity” theory or “multiregional evolution” model refutes this theory and states modern humans evolved from various species of Homo erectus who interbred with others that lived in
