Its heating up now!

Humans are easily adaptable to dry hot climates compared to humid climates and especially cold climates. Heat, an environmental stress, can prove to be very dangerous to us even though we are able to adapt to it quite easily. given how extremely hot temperatures can cause us to suffer from hyperthermia in which are core body temperatures (which are normal at 98 degrees Fahrenheit) rise beyond the normal temperature with it becoming life threatening at 105 degrees Fahrenheit and higher which will lead to organ deterioration and death.

Short term adaption: the most common short term adaption to heat is our ability to sweat through are 1.6 million sweat glands. Sweat cools are body through evaporative cooling that occurs when we sweat and our sweat evaporates


Facultative adaption: body hair varies in length. however shorter body hair increases the effects of evaporative cooling from sweat while longer hair decreases those effects and actually aid in retaining heat.


Developmental adaptation: having greater mass and shorter height aids in retaining heat and isn't suitable in high heat areas or situations as a person would heat up quickly. However being leaner and taller with longer arms and legs lessens the amount of heat that is retained. in addition people in hotter climates have darker skin while people in colder climates generally have lighter skin


Cultural adaptation: in order to accommodate hot weather we have designed thinner and less restrictive clothes. in addition we also have air conditioning and fans which make the area they are installed in cooler despite how hot it may be outside of said area.


studying human perspective across environmental clines is beneficial because it eliminates biased based on race. In addition its more accurate then judging by race since a persons skin color can change depending on their exposure to the sun with greater exposure resulting in becoming darker then you originally were while less exposure can make one paler in addition there are diseases that can cause one to change pigmentation and like vitilgo.


I would use race more like an aftermath of adaptation to show that environmental changes lead to the different variations of races that are accustomed to different climates.

Wonders of Language

Part 1:

        Initially I only planned on having a conversation with one of my friends but it ended up becoming a group conversation between me, my friend, and my friend's 7 yr old sister. So it ended up being a bit harder than I expected to communicate without talking or writing or body language but overall not all that bad since I was able to do slight head movements for certain responses that my friend was able to understand, although my friends younger sister kept asking why I wasn't talking and grew annoyed by my "lack" of action. In contrast my friend treated it like a normal conversation with me because he seemed to know I was paying attention in the conversation.
      As far as control of the conversation I pretty much and zero control in the conversation since I was unable to really voice my opinion in anyway or drive the conversation in any direction. meanwhile my friends younger sister had no control mainly because she was trying to figure out why I wasn't talking so ultimately my friend had complete control over where the conversation was going. my friend's little sister mainly asked questions although they weren't relevant to the conversation in question while my friend mainly went on talking while I listened and wished I could speak instead of give slight head movements when he asked me something.
     If we were all cultures clearly my friend's culture would be able to communicate complex ideas among themselves since they have the power of language and overall they would have an advantage over my culture that is unable to use language to communicate. In a modern situation that comes to my mind is how most major gangs have their own exclusive coded language in which they can communicate while police and the average individual are oblivious to and gives gangs an advantage to share their plans.

Part II:
      I thought that this part was going to be easy since I would be able to actually talk, but it couldn't have been harder. yes I was able to talk and express my opinion and yes my friend was able to respond to me normally and was able to understand me enough to have somewhat normal conversation, but I found it hard to fluently talk without changing my tone of voice, making expressions and especially making body movement and found my self stopping mid-sentence and stuttering at times in order to think about what to say next for a second while preventing myself from doing anything but speaking in monotone.
     Overall this assignment made me realize that hand gestures, at least in my case, aid us in talking. Being able to change vocal tone helps show a person's emotion and how they feel about a certain topic or situation. eye contact also helps show that a person acknowledges you and are paying attention to what your saying while hand gestures are able to help convey a point through imagery.
    Being able to read body language allows you to understand a lot about a person. for example when a person is lying, stressed, angry, sad, happy (truly or falsely) their body language reflects that for example when a person lies they make certain gestures unless they are in a state of mind where they believe what their saying is absolute truth then or they are really good at keeping or are able to throw people off by having abnormal yet natural body language they display when they tell the truth as oppose to just a straight face, their body movements consistent between telling the truth or lying. In addition being able to read body language allows one to interpret gestures that people make for things like stop, go, no, yes, etc. and allows for one to communicate silently which may be needed or just convenient in some situation.
