Humans: Where We All Began Humans have roamed this earth for thousands of years. Considering that, we can't help but raise the question of where we all came from. Around the 1950s, it was widely believed among European scientists that Homo sapiens originated in Europe or Asia around 60,000 years ago. Based on more recent discoveries by Mary Leakey and her husband Louis while excavating in East Africa, we now believe that Homo sapiens may have first emerged in Africa many years earlier. Of course it is impossible to know exactly when the human species first emerged, but based on fossil evidence, most paleoarchaeologists believe that around 6 million years ago, the human ancestral line split from that of the chimpanzee and evolved into a new group.

She was only around 3½ feet tall and had very long arms. Based on her body’s shape, she was believed to be able to walk upright on two legs and also climb trees with great ease, scientists believe that her species used resources from various environments, such as woodlands and grasslands. Judging from the evidence of large muscles on her arms and upper torso, she must have had very powerful upper arms and a strong chest. She had feet that were capable of supporting her entire weight, but her toes resembled that of a tree-climbing ape, being long and curved. Despite her physical resemblance to ape species, her body was very capable of supporting her weight while walking upright. She had thigh bones that were angled inwards and a short, broad pelvis that helped keep her body upright. These are both required in order to walk efficiently on two legs. Lucy was a very early stage of hominid species that have since taken on different shapes and become more and more capable of thriving on this planet. From studying fossilized bones such as that of Lucy’s, we can pursue further studies on how greatly humans have evolved over the years. (Human
"Where did humans originate ? " you might of asked. Humans originated from Asia, well people believed that. People believed that native people live in America because they were descendants of long-ago ancestors from Asia. Can you believe
2) Lucy is a collection of fossils from an early hominid species that is over 3 million years old. Lucy's fossils were discovered in Ethiopia, and Lucy was also very short compared to the average modern
Next where did the humans originate from? Humans originated from Africa. But why? The reason the humans where in Africa was because they were following their food or game and they migrated. They were also called nomads because they did not stay in one place they moved around and made their way here.
Humans began in Africa,they started using stone tools and fire to cook their food. They were hunters and gatherers, they gathered berries and other plants and hunted deer and other animals for meat. Humans then migrated to Asia and Europe, they spread across the continent. “ Genetic evidence suggests that soon after leaving Africa, they interbred to some extent with the Neanderthals and a mysterious population in Asia called the
After reviewing the evidence, I believe that Dr. Donald Johanson is correct in his theory that Lucy is the missing link between ape and man. The anatomy of Lucy supports Johanson’s claim. The knee joint of Lucy had an outward slanting angle away from the knee just like humans. Lucy reconstructed pelvis with its short and curved ilium indicates bipedal human qualities. Unlike the Piltdown man, Lucy stood the test of time, Johanson’s fossils through potassium argon dating was found to be at least 3-million-years-old proving the integrity of Johanson’s find. Similar archeological finds also validate Lucy. The 1976 Laetoli footprints support the theory that there were hominids walking upright during the time of Lucy. In 1924, Raymond discovered the Tuang child in South Africa, it displays similar qualities of Lucy, small brain and bipedal abilities. Additional finds by Robert Broom, Richard Leakey, and many other creditable paleoanthropologists further prove Johanson correct.
The exact history of how we came to be is one that is still very much unclear and is constantly revised. Many cultures around the world hold their own creation stories about the creation of the world and how the people came to be. But we all have one thing in common, the Earth.
Despite what gender, race, or even religion that you identify as, one thing is for certain, and that is that we are ALL human. To start off, I’d like to inform you that “humans” actually belong to a species called Homo Erectus. Dating back to more than a million years ago, this species once occupied Eastern Africa along with another species known as the Australopithecines. Homo Erectus, also known as “upright man”, is said to have migrated away from Africa after the Australopithecines went extinct, but scientists are still unsure as to where they migrated. It’s difficult for scientists to say exactly when and where Homo Erectus evolved because their fossils were not only found in Africa, but also in Europe and some parts of Asia as well.
There was a question leaved me confused at times. Where did I come from? Where did human come from? I heard many religious stories about the origin of human. However, those legends cannot solve my doubts. After I took this anthropology class, I got my answer. Modern humans evolved in Africa. Moreover, I learned that our bodies also contain small percent Neandertal DNA. What was the Neandertal? Neandertal, the scientific name of which is Homo Neandertalensis, existed roughly between 200,000 and 30,000 years ago. They lived in Europe eastward to Central Asia. In fact, in the past, scientists always thought that Neandertals were more likely brutal and stupid apes. However, Neandertals were smart like modern humans and owned their special
Lucy is a 3.2 million old ape that was found in 1974. She was the first Australopithecus Afarensis to ever be found. She looked like a mixture of ape and human. She is 3 and a half feet tall, from this they determined that she was a female because afarensis males are a bit larger than the females. The finding of Lucy is very important because it proves that
The ancient relative of humanity dubbed "Lucy" may have been one of a harem of girls that mated with a single male, according to research that suggests her species was polygynous.Among the earliest known relatives of humanity whose skeletons were made for walking upright was Australopithecus afarensis, the species that included Lucy.Members of the Australopithecus lineage, known as australopithecines, are among the leading candidates for direct ancestors of the human lineage, living about 2.9 million to 3.8 million years ago in East Africa.To learn more about Lucy's species, researchers investigated the area of Laetoli in northern Tanzania, which previously showed the earliest known footprints belonging to hominins humans and related species
To begin, Diamond talks about our evolutionary relatives, the apes. The history of humanity began in Africa about seven million years ago, when the African apes evolved into three categories. They evolved into gorillas, chimps, and humans. The earliest species of humans, Homo Habilis and Homo Erectus, became closer to modern humans in physical traits about 2.5 million years ago. One million years ago, Homo Erectus began to migrate out of Africa to Europe, Australia, Asia, etc. Homo sapiens first appeared around half a million years ago, having evolved from Homo Erectus. There is no perfect definition of Homo sapiens and therefore no exact date for when they first appeared. Still, scientists and anthropologists usually agree that Homo
‘Lucy’ was exposed by Donald Johanson, an anthropologist, with his team, went to survey Hadar in Ethiopia during the late 1970s for signs in understanding Human origins. On November 24, 1974 by the Awash River, Donald’s’ plan for the day was to update his notes but decided otherwise when one of his students, Tom Gray, joined him to find fossil bones. Both of them were on the hot waterless plains examining the sandy terrain when a fossil was spotted; it turned out to be an arm bone fragments on a slope. As they looked closer, more and more bones were found, including a jaw, arm bone, a thighbone, ribs, and vertebrae. Donald and Tom had cautiously examined the limited skeleton and calculated that a remarkable 40% of a hominid skeleton was salvaged,
In 2009, "Science" magazine published an article, said the success of Ethiopia found the fragmentary primitive fossils spell a female primitive bone. Scientists say that the ape, named "Ardi", lived about four hundred and forty years ago and had been one million years earlier than the other female primitive skeleton "Lucy", which had previously been discovered in Ethiopia, Earliest primitive bones.
Until recently, the oldest fossil species to provide evidence for bipedalism was Australopithecus afarensis, of which the best example of is the 3.2 million year old skeleton called Lucy found in Hadar, Ethiopia. According to article 19: Sunset at the Savanna, in 1995 Meave Leakey of the national Museums of Kenya and her colleagues made public the discovery of and older hominid species Australopithecus anamensis (getting its name from the Turkana word for lake "anam" having been found near lake Turkana and the site of another ancient lake). Leakey's team found a tibia from this creature that is quite human like and emphatically bipedal, "in size and practically all details of the knee and ankle
Named after the Beatles song, “Lucy in the Sky without Diamonds,” Lucy is an ancient, fossil of australopithecus afarensis, one of our predecessors. Lucy is 40% of fossilized skeleton of a three foot six, fifty pound female who roamed the Great Rift Valley 3.2 million years ago. Lucy’s male counterparts were 5 feet and around 105 pounds. This difference in size between the males and females is called sexual dimorphism and it happens in a lot of ancient and modern animals. Lucy was found in Hadar (a dig site) 217 miles away from Addis Ababa the capital of Ethiopia. Donald
