1. Environmental stresses are part of all lives and has a
great impact to all. Climate adaption is one of the many environmental stresses
humans have encounter and have to adapt to. When living in cold climate there
are many dangers that one will face such as hypothermia which is caused when
there is a drop in core body temperature. When living in cold climate usually the person
has a greater increase in body mass and a diet that consists in much fattier
foods which helps one to tolerate living in such harsh conditions and helps produce
an increase in body heat. Cultures in that live in cold conditions face this
high extreme weather is by using insulating clothing, houses, and fires. Other ways
people adapt to this is by limiting the amount of time that is spent outside
and leave those activities to warmer times during the day. In some cases families will sleep in groups
with one another’s bodies being pushed up against each other to help maintain a
warmer body temperatures during the cold winter months.
2. Four ways in which humans have adapted to the stress of
living in cold weather are:
- People who are living in such cold climates drink alcohol to help warm them. By doing this it helps to increase blood flow which thereby causing the feeling of warmth. But these results are only temporary and can be dangerous to do because it can speed up the loss in heat from the vital internal organs which results in a more rapid death from hypothermia.
- Body size and shape are a very important influence when living in cold climate. There is a high increase in body mass and compact bodies with less surface area which are more common when living in cold climates. It helps produce a high increase in body heat.
- When living in harsh subarctic regions another way many of the cultures adapt to the cold climates is by consuming large quantities of high calorie fatty foods such as such the Inuit (Eskimo) do. This knowingly increased the basal metabolic rate, which results in the making of extra body heat.
- The Inuit (Eskimo) also dress in thick and heavy clothing, often slept in a huddle with their bodies next to each other, and continued to be active when being outdoors.
3. The benefits of studying human variation from this perspective
across environmental clines is that we gather new information in which can
teach us on how to adapt into a new environment. We can study this information
and can receive so much from it. Yes this information can be very useful to
help us because it teaches us how one can adapt to a new environment and gives
us very valuable information.
4. Race isn’t the reason being why a certain culture can adapt. No matter what race one is we all have that power in being able to and have the capability to adapt into any environment in which is thrown to us. It is just a matter of teaching yourself on how to adapt and also by being taught and learning from other. All throughout society everyone is adapting into which ever environment they live. It is important to learn information such as this and spread it amongst each other because that is how we are taught and it is how we learn that one’s race isn’t what matters when it comes to adapting into a new environment because we all can adapt no matter which environment we cross paths with.
I like your example about the Eskimos and how they adapt the extreme weather throughout the year when sometimes I couldn't really tolerate California's winter. Well, I think it takes a while to adapt the extremities of the weather and the geographical location. Adaptation is very important in survival and in the study of evolution.
ReplyDeleteHi,
ReplyDeleteI found it really interesting to read that alcohol consumption is a way we adapt to the cold weather. I also never thought about blood mass and cold weather. I never really thought they had anything to do with each other. When I think about my own personal experiences, I am starting to realize that my own blood has changed from when I lived back east and now living in a warmer climate. Very interesting!
Good Job!
For the most part, very good post. Good coverage on background information and your discussions at the end are excellent. I especially liked your comment, "Race isn’t the reason being why a certain culture can adapt." That was very interesting and gets to the point that race doesn't tell us anything useful. It is an artificial, culturally based categorization of humans. That's all.
ReplyDeleteOne point: Remember that short term adaptations are going to be physiological traits and adjustments to the stress that will provide a benefit and help the organism respond positively to that stress. They won't be behaviors. So drinking alcohol in your first adaptation is wrong on two counts. First, it is a behavior, not a physiological response. Second, it actually harms the organism (as you mention) by reducing the body temperature very slightly and by reducing our ability to reason and solve the problem of cold stress. An example of a short term adaptation would be shivering. Can you think of any other?
I kind of had to guess which adaptations fit the categories requested in the assignment (short term, facultative, developmental, cultural) but they were in order. Make sure you help your reader follow your logic by clearly identifying things like that.
Other than those two points, good post.
