Yes using only movements was difficult because you couldn't really tell what people were saying, but you could tell the other person's emotions. Communication like this does obviously change how you interpret things and you really have to pay attention to movements and facial expressions cause that was what was telling the story. A speaking culture i feel would get more frustrated in having a conversation with someone who didn't because they feel they're speaking clear enough for one to understand and having someone communicate is a completely non symbolic way would be so different. Deaf people obviously communicate very different. People who do speak have to alter the way they communicate with them by not using their words but with hand gestures, pointing, and facial expressions.
Now could we last through 15 mins of only speech, yes but it was definitely different and funny. Basically talking like a robot being very monotone. When not using emotion you have to be careful on the way you word things because you can come off in a certain ways. Its kind of like sending a text without using "emojis" or "LOL". You don't always know how a person is feeling when you can hear the tone of their voice or see the emotion in there face. You can be saying something very serious and someone can think you are being funny if you word it wrong or they don't hear you say it. My friends were affected by not knowing what i was feelings and most of the time I was being funny and they thought I was being serious. So emotions really are more important than words. This experiment shows that we really do feed off others emotions and interactions. Because those things affect how a conversation is conducted. But yes there are people who can't really read body language. A benefit to reading body language because some people express more through actions rather than there words. I don't see anytime where body language wouldn't be a benefit honestly because I use body language so much and especially facial expressions. My emotions show all over my face, whether I'm mad or I just think you are crazy.

Piltdown Man Hoax
1. The Piltdown hoax was in the early 1900's. In 1912 in a small town called Piltdown, Charles Dawson found what seemed to be a ancient human skull. Dawson invited Arthur Smith Woodward, and Father Pierre to come help excavate the site further. The jaw bone that was found didn't look human at all, but more like a primate. Although the teeth seemed like they were that of human because they were a flatter surface. This finding dominated research on human evolution even though nothing else was found at the site. A turning point was made after WWII; a new technology was made up by measuring the fluorine content of fossils scientists could ultimately date them. In 1949 scientists conducted this test on the Piltdown fossils, it showed that the fossils were very young closer to 100'000 years old not what was thought originally which was closer to a million years old. It baffled the scientists, so finally in 1953 they performed the first full scale scientific analysis. They found during the tests that the fossils was superficially stained and was cut when it was already fossil and that the teeth had been filed down. And it further showed that the fossil actually only dated back 100 hundred years!
2. The human faults that came into play here was that when a man wants something bad enough he will make it happen no matter what he has to do. Whether it be lie, cheat, or steal. In this case lying and cheating. This affected things in the long run because more tests had to be invented to assure that this would never happen again. So that had to start testing to make sure the credibility of fossils and scientists was held up. It was clear that there would always be someone out there that wanted to get a head and cheat the system. But now they would know better.
3. The testing of fluorine content helped in dating the fossils to their correct time. There also was the first full scale analysis that would further reveal the how far off there were on dating the fossils, and show they were stained by someone and that the fossils were cut and teeth filed. Clearly someone faked the fossils. They found out the jaw bone was from a female orangutan.
4. You can't really take the "Human" factor out of science when you are looking for human life. I suppose you could make that your last resort when finding things. Rule out all other odds before considering human. This example was based of the deceit of one man though, it was a easy error to make in those times when people were looking for ancient man and someone had tried to forge their own ancient man fossils. When he knew there weren't any proper tools at that time.
5. The life lesson I take away from this, is to pay close attention to detail and to not take the word of human just because they try to place evidence in front of your face. You have to always take a step back and look at the big picture and do things add up.

Primates: Locomotor Patterns
Lemurs:
a.) Lemurs live on the island of Madagascar in almost every ecosystem. Most live and spend most of their time in the trees. Swinging from branch to branch in the rain forest tree canopy above.
b.) The lemurs locomotor pattern is vertical clinging and leaping, in a quadrupedal motion. They can leap very far distances and rarely hit a distance they can't jump.
c.) These primates have definitely adapted to their environment. Being able to leap far distances is an asset to them of course but there is certain times where they can not reach. That being the case they have adapted to making their way down to the ground and bipedally hopping sideways with their arms out most likely for balance; which has been known to be called the "dance-hop"
Spider Monkeys:
a.) Found in the tropical rain forests of Central America. They are definitely one of the noisier primates. It is a defense mechanism to ward off predators and to warn others. They yell and shake the tress when they see or feel danger.
b.) Their locomotor pattern is similar to lemurs but different because they don't use four limbs. They use four limbs and their tail! Their tail is one of their biggest assets. It makes for a interesting sight when you see them swinging through the jungle hanging from their tails.
c.) Spider Monkeys have adapted to make their tail very useful to them. Since they can hang from solely their tail which is strong enough to hold them up so they can use their others limbs to pick and gather food. They also have very strong hands which helps them grasp tighter and move faster for a quick getaway from predators.
Baboons:
a.) Baboons tend to live in much dryer climates like the Savana. They also spend more time on the ground rather than in the tress; and they eat various things like fruit or small rodents.
b.) The locomotor pattern of baboons is walking on all fours (quadrupedally) because they stay on the ground mostly and don't normally swing from trees.
c.) His environment is perfect for him, why adapt his feet were made for walking and that is exactly what he does! No need for a tail like a spider monkey. His four limbs do him well, and most of the food he eats is found on or near the ground.
Gibbons:
a.) Gibbons are found in the tropical and sub-tropical rain- forests of South, Southeast, and East Asia. They tend to eat fruits leaves and slimy little insects. They also are pretty quick and swift primates their predators find it hard to catch them; the Gibbons definitely give them a run for their money.
b.) Gibbons locomotor pattern is traveling from tree to tree kind of the same way you would on monkey bars in a playground; one hand in front of the other. They also walk sometimes, not on all fours like the baboon but bipedally on two feet across branches. Although they do that far less often, then swinging from tree to tree.
c.) The environment influences the Gibbons pattern, since they have such long arms and very light weight they adapted to use the means of travel they do now; swinging from branch to branch. It helps because they find everything they want or need high in the tree tops. It also keeps them far from harm and predators.
Chimpanzees:
a.) Chimps are very social primates they are usually in packs found in the African rain-forests, but they can also be found in grasslands as well. Chimps are some of the most intelligent of all primates and they seem to know it.
b.) A Chimps locomotor pattern is mainly walking on all fours (quadrupedally) but also bipedally. When they travel quadrupedal style they are also known as "knuckle walkers" like a gorilla. When chimpanzees on the ground they tend to stay in packs. But like other primates they enjoy a swing in the trees as well. The trees is where they tend to sleep and eat.
c.) Their environment and abilities definitely plays to their advantage as they are comfortable on the ground or in the trees.
Environment does play a role in the way primates do things; but most primates are very smart they learn and adapt to everything because of the size of their brains. But yes some primates would probably suffer if they were to live where the baboons choose to live in a place like the Savana. And that is because some of them tend to stay in the trees and move quicker and stay safer in those environments. A good environment is very important to the well being of a primate.

Charles Darwin: Evolution
Influence on Charles Darwin's Theory of Evolution
Thomas Malthus had the most influence on Charles Darwin; Malthus was the first to venture into the thought of natural selection. When Charles Darwin discovered the stepping-stone to the idea of natural selection now known as Malthusianism, it made him think more about how different organisms could survive in any given environment. Although Malthus only thought natural selection was among the human race Darwin took it one step further and believed natural selection applied to any living organism.
The biggest impact I think Malthus made on the scientific community was putting Darwin onto natural selection. Most of Malthus' findings were based more on the economy and how the growing amount of people their were the less food there was. So I think him opening the door to Darwin's findings on natural selection was most definitely his largest impact.
- Resources are limited.
- Organisms with better access to resources will be more successful in their reproductive efforts.
- Who gets better access to these limited resources?
These points speak all about exactly what Malthus was a publishing in his journals. They all talk about needing resources to survive and without resources its harder and pointless to reproduce. Also people in better situations who can provide the resources to be stable enough to reproduce.
Could Darwin have developed his theory of natural selection without the influence of Thomas Malthus? I'm sure he could. Darwin made the idea far larger than that of Malthus, Malthus just gave him a faster nudge in the right direction. Although I'm sure it wouldn't have taken him long on his own.
As for the Churches attitude about his findings they made him hide it from the public for a few years. He had only told a few people in his small circle. The church didn't want things out to make others question or stray from the words of God. The church almost always would shy away from rebellious thoughts and scientific beliefs.
