Last Human Standing

Have you ever wondered why are we the only human left alive when there was so much more humans that lived the same time we did? Well with extensive research and investigating we found out lots of useful information that helped us answered these questions. We had 20 types of ancestors that we currently found which means we had to live at the same time and at one part of time 4 different types of human lived together. One of the most successful humans apart from us were the neanderthals which lived 400,000 more then we have been living. They had bigger brains then us today but didn't use them fully. The huge change that made us who we are now was 140,000 ago when we at the brink of extinction. It was when a mega drought was happening and in that time we were forced to live at the shore were we couldn't get lots of meat from animals on land, so we had to adapt. One thing that archaeologists found was a pit that had lots of bones along with quartz tools and it is one of the most inaccessible places in the world. In the past it was a open hole in the ground that we think the early humans used as a burial site. Archaeologists found lots of fragments but when they combined them they found about 30 complete skeletons. The place they take the bones to investigate is the center of human evolution which there are only 4 in the world. What we found out from all of this is that the neanderthals had a flat skull which caused the part of the brain for speech to be smaller. One reason we continued living was that we many new tools that we could use unlike the neanderthals that just took rock and a huge piece of wood to kill the animal. We made spears for throwing which made us able to kill a animal while still being a safe distance away but the neanderthals had to come close and risk their lives that why they had short and hard lives. When there was a mega drought we when to the shores and lived in caves and we think that all of us descended from 600 individuals but that's only a idea. We adapted in the way that we started eating fish and clams that when the waves were low we could gather. In that time period we developed art and culture. One interesting face is that we pushed the neanderthals out of their area. We will one day find out all the detail but until then we are still evolving.

From Grunts to Grammer

There is one question that still troubles scientists and that is when we started to use complex language. Language is constantly changing and even today its s going through its own little evolution. It is obvious that language is the product of the need for socialization. So we can roughly conclude that the first traces of language appeared over the first camp fire, and slowly evolved from grunts to complex sentences. Dr. Jeffrey Laitman was the first one to conclude that homo Habilis, the earliest human might have been communicating because there is evidence that parts of the brain that were required for speech were present in them. For speech we need a larynx also known as voice box to make sounds and sometime in the past our voice box went lower in our throat so that we could make sounds but for the animals it stayed high up. Some scientist assumed that our voice box subsided when we needed more air to hunt prey. In the past we hunted by using persistent hunting and it is when they chase a animal until it can’t run and gives up. The extra need for air made our voice box lower so that we can breathe through both our nose and mouth. One suggestion to when we started speaking was when we first started to use primitive tools; we needed communication in order to pass on the craft of making tools. Along with migration comes the need to cross the seas and that when scientists think that we started to use more complex language because to make a boat required greater skills. The problem is that we have no solid evidence so we can’t say for sure when it started.

Taming Fire


Have you ever wonder when did we start to use fire and why we have it today? Well thanks to science we can figure out that answer out. Playing with fire is dangerous and it still is today, although back in the past one person was so interested in fire that he tried to see what he can do with it and they found out ways of keeping them warm and cooking food which made it easier to eat. There’s no doubt that natural occurring fire were scary to them but when some animals die other animals can eat it. The idea we have it that we have been using fire for 250,000. We know this because we find hearths. Hearths are the reaming of a fire place and it can commonly be identified with a circle of rocks, around it we usually find charred bones and stone tools. Another way to see if there was a fire is that we can check for changes in the bone chemicals because a contained fire is hotter than a wildfire and this method suggest that we have been using fire for 1,000,000. A cave in Swartkrans has animals remains and when they examined the bones it shows that it was in a contenting fire but those people who inhabited the cave didn’t know how to start a fire so they would have to take wood and light it from a naturally occurring fire and run back. These sounds crazy but imagine the improvements for them they could cook and keep warm. The use of fire is maybe why they migrated from Africa to colder places like Europe. This shows that our ancestors observed and tried to understand it which today’s scientists do!

On Our Own Two Feet

Have you ever wondered when and how we started walking? Well this question has been around for many years and we are still missing some key elements to confirm it. Walking upright on two legs is a very rare characteristic that we have and many other animals don't. Although we know that walking upright is very old it came before our increasing in brain size. One idea that most people get wrong is that a chimp isn't are ancient ancestor but it has shared a common ancestor. Even thought we do share common characteristics, they are still not our ancestors. One of our most know primate are the afarensis which lived half way between us and chimps. We all have a hole at the back of the skull that they use to tell a difference for us that hole is horizontal and since chimps walk on 4 legs theirs is slightly curved. For the afarensis the have a horizontally facing hole which shows they walked on two legs like us. Afarensis weren't the first one to walk on two feet their were many more old up to 6 million years old. Scientist were shocked when they heard this since they thought it was the opisite that our brains got bigger then we started walking.C.Owen has one of the most known theory that stats that they walked on two legs so their arms would be free so they could carry food or tools.They are still trying to find why we stared walking but the important thing is that we walked and that made a big difference.


Why We Study Human Origins

Didn't you ever think were we come form and how we found out? Well we only have limited information 
 since we cant find all the fossil. There are many question that we would like to have the answer for but we don't have the evidence to prove it. In the past people thought that are origins are from myths but one day a scientist Charles Darwin comes and gives everyone a new idea that plants and animals evolve to adapt to thier environment. After a while sientist accepted the idea. Thomas Henry Huxley also had a theory that anatomically African apes and humans were related. Although in their times no hominid fossils were fund so they had no evidence.Raymond Dart was the first one to find a hominid fossil which enforced Thomas's and Huxley theories. They also found stone tools that they used and that suggested that the were predatory. Their are lots of other idea like that we were knuckle walkers or bipeds living in water. Although it is still helping us understand our origins better.

Who's Who Among the Early Hominins

Have you ever wondered how scientists and archaeologist identifying a 3 million year old fossil .Well they have many methods that may need high tech machines or it might just take a little bit of knowledge about early hominins.There are many different hominins that we record by the changes that happened to them. Although we don't find many fossils and whole bones when we find them but we still can recreate them. Most people call the early hominins ape man because they resemble monkeys. One types of early humans are the sahelanthropus tchadensis which are the oldest ones found they data back to 7 million years and as it seems they had a chimp like brain and not much features that we have today. Homo habilis also known as handy man is one of the best known fossils. It shows that the people from the pas killed little animals for food and made tools that's why he is called the handy man. Homo neanderthalensis are one of the earliest human and they show human like features of the skull and height. As you see their are many different types of early humans and their are still more to find.

Stonehenge Mystery

One great mystery that scientist and archaeologist are trying to uncover is the mystery of the Stonehenge. Stonehenge is a lot of rocks put together that are put into a specific order but we don't know the reason. Their are many theories and tales to who built it and why. According to folktales they say that Merlin, a wizard, use his magic to carry the stones and put them to place. Although scientist disagreed so they went to find the real answer. So they cam up with many different theories but the ones that i thought were interesting. SO the first theory is that it was created by the people who lived there and was a astronomical observatory because it lined up were the sun will fall because of the soloists and they have it also for winter so that cant be a accident. Another theory that i thought was interesting was is that it was a landing site for aliens. Since some people believe that ancient people couldn't build that because it isn't easy even with our technology so with theirs it impossible. And my last theory is that it was a place for the dead while the woodhenge was for the living and that their were buried some important people. There are many different theories and until we can confirm one of them we have to be open minded to all ideas. With every idea we are closer to figuring it out.

Human Ancestor May Put A Twist In Origin Story,New Studies Say

Archaeologist found 2 million year old fossils and possibly skin from a pair of primates. This primate is know as the Australopithecus sediba and it was discovered in Malapa region in of south Africa in 2008 and was described the first time last April. Scientist made many test and for example the primates anatomy showed that it is able to make and use tools. They also found what they think is fossilized skin, So they made a open-access experiment.They say that they bones are from a really special ere that we don't know much about. The two primates fell in a chasm and they bacteria trap persevered them. From the legs they saw that their ankle is similar to ours and that they could walk on two feet. The odd combination of feet suggested that they could also climb up trees as well as walk. The endocast showed that the brain was similar to ours but small. The primate had a long thumb so it had a precision grip. In fact they say that they might have had better grip then us because of their longer thumbs. This could change history but the Washington sate university is not yet ready to make drastic changes to the time line.

Huge Gladiator School found Buried in Austria.

Archaeologist have found a new huge school for gladiators that is roughly the size of two wallmarts. They found many equipment like a training dummy were they would practice their moves. All the Archaeologist said that is huge and one of the most interesting event in their career. This is a major part of evidence for the roman history. They didn't yet actually dig that up they used tractor-mounted radar equipment that gives a 3d image of was underneath. They found that their were many things under, like a mini amphitheater. Archaeologists think that the gladiators were slaves, but they are not sure. In the past their were gladiators slaves and people that are free, that wanted to become a gladiator for the fame and glory. They estimated that it is 200,000 square feet. They also find a part were they could keep animals for gladiators to fight with them. Excavating this site would add lots of valuable information on life's of gladiators. Their is also a cemetery near but with bones to show the trauma that they went through.

How do Historians learn about the past?

You probably thought how do historians learn about the past and how they find all the things required to say that, that happened in the past. They find that out by finding primary and secondary sources. Primary sources are documents or physical objects. Secondary sources are source that interprets and analyzes primary sources. There are also written and non written sources. It is really hard to figure out what happened in the past because there were no written sources and they didn't get the perspective of woman. Their are five major steps of how they will do for finding evidence. First they gather a variety of sources then they categorize sources to written and non written. Then they evaluate sources, questioning time of origin, after that they evaluate source and finally share their findings with the world. So that is how historians learn about the past.

In the past where did the humans tend to settle and why?

In the past people had move and migrated for many reasons. There had been many major movement in history all having to do with similar reasons. Most people moved because there wasn't enough resources or the living conditions were harsh. Although some people did it for greed. They come were some people have already settled and then they kill the people and take all their resources. People moved south because it was warmer and they could grow lots of different plant and breed animals. For example when the barbarians attack Romes home land they went away from some countries they concurred to defend them. People settle where the their was good soil for crops and a comfortable climate. They wouldn't settle in  the Sahara or Antarctica. Sometimes people don't want to move so they have to adapt to the environment.Some of the reasons why people move are war,climate,living conditions and much more. People also move because they may not like  the government of that country so they go to another country and some other people maybe like that government so they move in. Migration don't just have to be with people many animals migration for example red crabs. As you can see in the past people have migrated for many different reasons.

What is History and Why Do We Study It

History is the study of the past. It is very important for us to study history, we study it to not make the same mistakes and not have the same conflicts. History can be changed by finding new evidence but to go back in time and change it, we cant do that. There are countless reasons why we study history some of them are so we dont repeat mistakes like wars and slavery. We also learn from where we came for our heritage and how people of the past use to treat something that could help us in the futer. History is not something boring and just remembering dates they are stories that can be really interesting.

We are not makers of history. We are made by history.
Martin Luther King, Jr. 


I think that this quote is really good because it describes history really good it means that we don't make history but we are history. Eventually we will become history and the people of the futer will use us to learn from our mistakes.
