Short term would be shivering. The body will create heat by shivering and allow the body to maintain the same internal temperature.

Facultative would be blood flow. Constricted blood flow allows the body to keep the main organs alive in case of hypothermia.

Fire would be developmental. In order to stay alive you have to stay around a heat source allowing the human body to stay alive and healthy.

Cultural would be animal hide skins or any sort of bug clothing. To survive in the environment you have to adapt and wear more clothing outside.
3.The benefits is showing how different people adapt to their environment. This can help us adapt to our environment if we were to change climate or move and live in another location. 
4.I would use race to explain the cold weather because people who do not get much light will have lighter skin. Environmental influences give race an explanation to why it happens.

    The first section ask you to not just identify a stress but also explain how it negatively impacts homeostasis.

    Good on short term.

    Vasoconstriction actually works to limit loss of heat through the skin's surface.

    Developmental is a genetic trait that evolved over many generations. "Fire" doesn't qualify, though that could be a cultural trait, correct? An example of a developmental trait is a short, squat body shape. This is explained in the resources in the assignment module in Canvas.

    Good cultural adaptation.

    "This can help us adapt to our environment if we were to change climate or move and live in another location. "

    How would this work? Most of these traits are biological/physiological/genetic and we have no control over them. None whatsoever. So how can this help us "adapt" to other climates, other than cultural adaptations? Is there a way we can use this information in some concrete, technological way? Can knowledge on adaptations to cold climates have medical implications? Help us develop clothing that retains heat more efficiently? Can we develop new means of home/building construction that might help increase heat retention? How can we actually use this information in an applied fashion?

    "I would use race to explain the cold weather because people who do not get much light will have lighter skin."

    A couple of points here: First, skin color is a response to solar radiation stress (along with Vitamin D absorption), not to temperature stresses of cold or hot.

    Second, is that actually using race, or are you just using the adaptive response and layering race over top of it? Can you really use race to explain human variation? Understand that it is perfectly acceptable to answer this question with a "no".

    To answer this question, you first need to explore what race actually is. Race is not based in biology but is a social construct, based in beliefs and preconceptions, and used only to categorize humans into groups based upon external physical features, much like organizing a box of crayons by color. Race does not *cause* adaptations like environmental stress do, and without that causal relationship, you can't use race to explain adaptations. Race has no explanatory value over human variation.

    I do appreciate that you note that using environmental stresses helps us understand *why* we adapt as we do. That is part of the issue of the using a causal factor.

    A little short throughout here. More explanation and detail needed.

Language Experiment

Part 1 1. Not being able to talk was a barrier that I never noticed. We use language all the time to speak so this was a very big challenge for me. The experiment consisted of my father and I. At the very start he was trying to guess what i was trying to communicate with him. I could point at things but he was having a hard time understanding me. At the end of it the conversation did not get anywhere. 2. My father was in charge of the conversation because I was the one who could not speak. Since I could not end or start a new topic he had to just keep the conversation alive or just start a new topic. If there was another person in this experiment I would definitely be excluded. The only response I could is yes or no answers. The two individuals who have the voice could have power because they can express their own opinion where I just have to follow along because I cannot communicate with them. 3. The one population who uses spoken language can express their ideas easily and more co...

Week 1- Historical Influences on Darwin: Jean Lamarck

One of the individuals that that influenced Darwin's Theory of Evolution was a French naturalist named Jean-Baptiste Lamarck. He developed a theory called the use-disuse theory. One of the contributions Lamarck made to the scientific community "was only one of the two mechanisms he proposed. As organisms adapted to their surroundings, nature also drove them inexorably upward from simple forms to increasingly complex ones"(O'Neil). Lamarck was trying to say that any species of animal doe not have genetic deficiencies and that they cannot go instinct. This theory of Lamarck is inaccurate because "only those traits that are influenced by genetic information contained within sex cells(eggs and sperm) can be inherited"(Jurmain, Kilgore, Trevathan, Ciochon, Bartelink 31).  This allowed Darwin to question whether or not a species can have deficiencies in the genes. He also had to question whether or not a species can go instinct. This allowed Darwin to go on and do...
