Human Variation : Cold Climates


BRRR It's Cold in Here 

1. The negative impacts on the survival of humans homeostasis in cold climates  is that there is constant danger of developing hypothermia. Because the body automatically maintains stable core temperature of 98 degrees Fahrenheit. Hypothermia begin when the core temperature reaches 94.F, below 85.F due to the body staying in the cold the body's natural temperature system fails and with this continuous decline in boy temperature can result to death. When the temperature reaches below freezing the body can undergo obtaining a condition called Frostbite.



2. The Short Term Adaptation : In a cold environment our body will quickly respond by shivering, which is a bodily function generating heat to the cold areas on our body. The increased muscle activity in shivering produces more body heat


The Facultative Adaptation : In cold environment we depend on our bodies to produce the internal heat we need, in which the response is to narrow the blood vessels near the skin (vasoconstriction) preserving body heat by reducing blood flow, that's why sometimes our hands become slightly numb. [ if the body remains in the state of vasoconstriction can result into Frostbite]. The body converts from vasoconstriction to vasodilation ,increasing the warm blood flood, to the skins surface in back and forth function to reduce risk for both conditions 

The Developmental Adaptation: People who live in cold environments consume large calories of fattening foods to add extra heat to the body, their body are more round and thick, The thick fat is coated on the vital organs of the chest and abdomen parts of the body, even when heat is loss the core boy temperature remains the same.




The Cultural Adaptation: In cold environments people will be inclined to wear clothing, that does not expose the bare skin and keep their bodies warm, when it gets chilly out we think to wear a jacket to preserve out heat. Eskimos, living in the northern region of the earth, wear heavy stocky clothing, at night they sleep in huddles where they lay their bodies next to each to retain the heat, and remain active outdoors when it's warmer out. In our environment, when it gets cold we use heaters and blankets throughout our homes to keep warm, catering to hot chocolate and  
sitting around the fireplace. each culture have their different ways of with the cold





3. The benefits is that we are learning how other cultures deal with their environments an taking note we can apply that same knowledge to ourselves if we were ever to deal with that kind of situation. Nature is unpredictable and is not always accurate even in a nice warm climate the weather can change a bit and become cold so it is wise to at least take these variations into consideration, being cold for too long can cause a person to become sick if your not dressed warm enough and all can cause the body to deal with abrupt change if not taken care of in these situation. So the benefits is very helpful to obtain this information, who knows you might want to go to a climate where a lot of snow is conducted.

4. The two races I will compare are eskimos and blacks, since my subject is on cold, the northern regions are more suitable for people of white skin because they have little shielding pigmentation and the solar radiations there is weak, whereas blacks will suffer in colder regions because it prevents them from producing Vitamin D. Ultaviolet Radiation must penetrate the skin in order for the body to produce Vitamin , and people in northern climates lack Melanin. The environment is pretty much where it is best appropriate for us and that our skin is adapted to the climate of that area. Its not so much about race when you think about it because if the world were to be under one specific climate we probably would all have the same color of skin. But from the wide variety of climate we differ, this is what nature does and as we adapt to these variations it contributes to our survival in that area. In a sense, natural selection is very convenient for us because where ever we are it suits us best by the reaction of our skin, and that is where we belong in order to live.

Language Post

 PART 1

1. Did you feel the experiment was easy?


   It was kind of hard because I couldn't use any kind of language, I pretty much had to emphasis my body language to the smallest detail in order for my partner to understand what I was trying to say. I had to repeat myself a lot because it's not easy trying to have a conversation with someone and you have to use your body to express how you feel. I had to use a lot of facial movements and hand gestures to where my entire body was involved in the conversation.


2. What were the impressions of your partners in this conversation? Did they alter their way of communicating with you because of absence of symbolic language?


  My partners impression was it was difficult to understand what I was saying and at parts it didn't make any kind of sense in communications but when I repeatedly acted out my response. Yes they were guessing what I was saying so they substituted what I was intending to say with their version of what they think I was saying, and if it was close enough I gave an accepting response letting them know if they were close to what I was saying.


3. I would say the culture that has the best technique of communicating complex ideas are the ones who are able to speak, because they are also able to use body language completing the form of language at 100%. Speech is very quick to understand and you do not have to directly face someone when talking to them. A person can talk from across the same room or in another room and at a distance the can yell to get your attention, but the person who is only limited to body language has to be watched, while predicting everything they are trying to say, the conversation is longer and harder.

  The people who are deaf and can not hear themselves speak are limited to using body language which they have to develop using sign language in order to be understood. But in this case a person having difficulty speaking, not so much as deaf, but some with speech impediment (mentally disabled) will be able to communicate because they can hear the person talking to them but they would have to use a lot of body language to be understood, which is kind of exhausting and frustrating if a person does not get it. and lastly, our very own babies who we have a very difficult time communicating with them because they don't recognize language and its hard to understand them, but they understand us but are not fully capable of using speech to their advantage, so they fully use body language to try to get parents to satisfy their needs.

PART 2


1. Were you able to last the full 15 mins of using only speech for communication? What made this experiment difficult for you?

   No I was not able to last as long as I did with the non verbal part of the assignment, the conversation became very meaningless, understandable but eventually we stopped talking for a long time being unable to expression myself fully. My partner kind of used some vocal intonations but it was hard trying to have a conversation in that particular manner. Eventually our answers were becoming shorter and shorter to simple answers, we sounded like robots and in a sense it was a non human.

2. How was your partner in this part of the experiment affected by your communication and limitations? 
  
  there was no empathy in what I said and everything I said was very shallow as if i did not mean anything I was saying. There was no serenity in what I was telling them and it made the conversation pointless to move forward because it was not interesting to hear the monotone within my voice.
 

3.What does the experiment says about our "signs" in our language, i.e., how important is non-speech language techniques in our ability to communicate effectively?

  Because we have use a lot of emphasis in our communication to create and effective impact on how we feel about what we are saying,( i.e. Body language sums up 80% of our communication leaving 20% of language to completely a successful conversation.) our emotions is what causes us to communicate and we use that to express our inner selves well enough for the people to understand either how important or less important the topics effects us.

4. I would say people who have difficulty reading body language are some people who are not allowed to express themselves much, or who are entitled to not being taught to speak, but generally we are a very visual species and body language is not hard to read.

  The benefits is that we can read emotions with body language, it reveals to use how people are feeling the facial expression tells us everything about the way we feel or how we want people to feel, and we fully get those feelings out by either our hand gestures, facial movements, some types of thrust with the body. When a person is telling a joke they have to act out the person they are impersonating or change the voice intonations to a certain pitch to mock a person so that joke is funnier to their audience. 
  Well since our environment has changed with vast technologies its not required to reading body language by chatting over the web, you can communicate effectively without having to use any kind of body language and still the other person your are conversing with will understand you.
