Week 5 - Racism - Variation

Image
In humans, maintaining a healthy body temperature of about 98.6 is an example of homeostasis. This means that the normal functions of the body that help to keep this body temperature and the parts that help make it function as so will maintain an equilibrium. It is important to understand that a healthy body temperature can also vary for different reasons such as the metabolism, hormone levels, physical activity, and sometimes the time of day can make the temperature fluctuate by as much as one degree Fahrenheit. Elderly persons sometimes have a lower body core temperature.     If an environmental stress such as a more extreme cold temperature is added, it will negatively impact the survival of humans by disturbing homeostasis. In temperature below 85 degrees Fahrenheit, the body would begin to cool rapidly because it’s regulating system will fail and it would result in death from hypothermia. In extreme cold temperatures, the human body would be affected in ...

Week 4: Piltdown Hoax

https://australianmuseum.net.au/learn/science/human-evolution/piltdown-man-skull/   Jealousy and the desire for approval were some of the human factors that lead an amateur archaeologist to pull off a hoax that fooled the science community for over 40 years! The hoaxer was Charles Dawson joined by England’s leading geologist Arthur Smith Woodward of the Natural History Museum. Together they made discoveries of skull fragments, a set of teeth, a jawbone, and primitive tools they said were used by the individual. They reconstructed the skull fragments and hypothesized that this was evidence of a human ancestor that lived 500,000 years ago and he was named, the Piltdown Man. Charles Dawson’s prestige held back any public criticism of his claim and although not all the scientific community accepted their claim, it was accepted in good faith. The varying effects on the scientific community came after Charles Dawson passed away in 1960 and no more of these ancient remains were...

Analogous and Homologous Traits

Image
The human arm and the wing of a bird have homologous traits.   They both share the same types of bones because they both have evolved from a common ancestor. Although they have the same types of bones they are used in different ways. From the outside they look very different. The human arm is covered in skin and the bird wing is covered in feathers. From the inside they have very similar bones. These bones include the humerus, radius, ulna, carpals, metacarpals, and phalanges.   Although these two species have the same types of bones, the human arm and the wing of a bird have been modified to conduct different functions.   Humans use their arms to reach and pick up objects. Birds have evolved into wings that help them to fly. It is believed that humans and birds evolved from a common ancestor. The common ancestor an ancient reptilian creature appeared to live 320 million years ago. https://www.nytimes.com/2016/06/25/.../scales-feathers-hair-common-ancestor.ht...

Scientific Method Scenario - Week 1

Week 1 -- Scientific Method Scenario Blog Post Scenario: About mid-way through the semester, in a class you are taking on campus, you become increasingly irritated by a student who sits in the back of the class. The student always manages to fall asleep about 15 minutes into the lecture. Normally it wouldn’t bother you, but occasionally he lets out a snore that breaks your attention and disrupts the class. The instructor has repeatedly asked the student to work harder to stay awake, but he is not having any success.  1.       1.   It is possible that the student is taking allergy medicine prior to coming to class and the medication is causing drowsiness and for the student to fall asleep. 2.        2.  Test: a.        I would test this hypothesis by meeting the student before class and suggesting non-drowsy allergy medicine before our class, which the student purchases at the booksto...

JC-Anthro101BlogPracticePost

My name is Josephine C. I'm creating a short post for practice for this summer course I signed up to take: Introduction to Physical Anthropology. The question I'm answering is: If I were stranded on a deserted island, what two items would I take with me and why? I believe I would have to go with two practical items. First a knife and a second a fishing net.  I think to survive these two items would serve best. A fishing net would help to fish and that would provide a good source of protein. And a knife would be a helpful tool to serve many purposes.  I feel an anxiety coming over me just thinking that I would have to survive outdoors, and hope I would never find myself stranded on a deserted island. However, when given a choice of two items I would hope to have these both.
