Human Variation and Race

Image
A normal healthy individual's body temperature is about 98.6 degrees Fahrenheit. When the body senses it is too cold the hypothalamus will send signals to your muscles to shiver and create warmth to maintain homeostasis. Climates that are extremely cold come with the risk of the body going into hypothermia. This is a life threatening drop in core temperature to subnormal levels. Hypothermia occurs when the core body temperature drops to 94 degrees Fahrenheit, thus disrupting the body's ability to maintain homeostasis. There are many cultural adaptations that humans have used to adapt to this stress. One of them is drinking alcohol to keep warm. This increases blood flow to the body's extremities and provides a feeling of warmth.  Another adaptation that humans have used is insulated clothing to stay warm. In cold climates it helps the body keep in heat wearing windbreaker jackets, hats that cover the ears, mittens to cover the hands and thermals under their clothin...

Language Blog

The first part of this assignment asked us to engage in a conversation for fifteen minutes where we were not allowed to use any version of a symbolic language. I had my husband and my mother participate in this experiment with me. This part was fairly easy. I was more on the outside of this conversation than anything else. They talked between each other and I sat back and listened. I feel because of my absence of communication it was easy to not have to include me in the conversation. For this segment the other parties were in control of the conversation. They changed topics and asked each other questions. They even asked me a question and while it was some work to get the answer across, it only happened one time. I feel because I am a little more of an introvert, I am okay with sitting and listening in a conversation as opposed to actively being in it. For the most part I was excluded from the conversation. If we think of this as a balance of power, the party who had the ability to ...

Piltdown Hoax

In 1912, an amateur archaeologist by the name of Charles Dawson claimed to have found an ancient piece of a human skull digging in a gravel pit in the small town of Piltdown. He started working with Arthur Smith Woodward, England's leading geologist of the Natural History Museum. Up to this point scientists had found remains of primitive humans in France, Germany and Asia, but none in England. Charles Dawson dug up a jawbone thought to have been part of the same skull, it was a major surprise because it looked more like an ape, but the teeth were worn flat much like a human. With this discovery, they thought they had found a common ancestor of a human and an ape. In December of 1912 at a meeting for the Royal Geological Society, scientists could now see that England had found fossil remains and their ancestors could actually be the oldest of them all. They called the discovery "Piltdown Man." After finding  more fossil remains, it had silenced those who were critics. Howe...

Analogy/Homology

Image
1.         a.   A cat and a whale appear very different on the outside. Cats have four legs and dislike water so they spend their time on land. Whales on the other hand are the opposite; they do not walk on four limbs like a cat. They spend their time swimming in the ocean, propelled by fins. b.       The homologous trait that these two animals possess is actually the forelimb structure of their bones. There are actually many species that share some type of forelimb structure.   The cat uses its front legs to walk, run and climb. They use the power of the forelimbs for speed and power. The whale uses its fins for swimming. The trait exhibits differences in the two species because they are influenced by the environment they live in, water versus land. This is why the cat has limbs and the whale has fins. c.        Given that both a cat and a whale are mammals; their common ancestor t...

Historical Influences on Darwin

I believe Thomas Malthus had the most influence over Charles Darwin’s development of his theory of Natural Selection. According to Brittanica.com he actually anonymously published, An Essay on the Principle of Population which many took notice to. “He pointed out that in nature, there is a tendency for animal populations to increase in size, but the amount of resources remains relatively the same. Therefore population size is held in check by resource availability” (Jurmain et al., 2014, p. 32). Based on the main arguments held in Darwin’s theory, it seems Thomas Malthus touched on a major one; that resources are limited. No matter what has happened in the many generations that Earth and the population have changed, there has always been a struggle for resources. The saying my mom used to always tell me is that there will always be someone with more than you and someone with much less whenever I happened to seem ungrateful for something. She is not wrong, it is a harsh reality that so...
