short term adaptation - of over heating would be sweating, sweating allows your body to releases beads of water that evaporate off the skin and temporarily cool you down.
cultural adaptions - when living in extreme weathers of heat, we've learned its not the best decision to go out in a snow jacket and snow boots. we all tend to wear lighter, more breathe able clothing such as tank tops and shorts to allow the body to release extra heat.
faculative adaptation - the less body hair one has, the quicker they'd be able to shed the excess body heat.
developmental adaptations - skin color is one of the factors, people living in hotter climates have darker skin from the sun. also body size ties with the amount of body heat one retains, a leaner more fit body holds less heat compared to a fattier body structure.
i believe the benefits of studying human variations across environmental inclines helps us all out because it opens up our eyes that it is based on genetics, not off of ones skin color due to the fact that it fluctuates and also not particular regions because people

Hi Taline,
ReplyDeleteYou made very good points in your blog. I also chose heat and made some of the same points. But you added a few that I left out. The lack of body hair was an adaption that did make an influence to heat. I also forgot to mention the fact that body size is a factor. Make sure to add some photos!
I did have them! That's weird that they don't show anymore! I added the links to them instead! Hope it works now!
ReplyDeleteI emailed in response to your email about the images, so make sure you check your inbox.
ReplyDeleteOkay on your explanation of heat stress, but a little more background would help. Why is overheating a problem? What damage happens to the body when it gets too warm? Sweating can help with overheating, but vomiting is a sign that something has gone very wrong. It isn't an adaptive response.
Correct on the short term and cultural adaptations. Body hair is not facultative. It's more likely to be developmental, but most animals have body hair even in hot climates, so it would be important to explain why it is not adaptive to humans. Regardless, a facultative adaptation to heat is vasodilation.
Skin color is an adaptation to solar radiation, not to heat. Body shape is a developmental adaptation to heat, namely with a thin body structure that helps to dissipate excess heat. Check out Bergmann and Allen's rules for this.
Your paragraph discussing the benefits of the adaptive approach ends abruptly but you are on the right track.
Missing the final discussion on race?
I now see three images. Can you identify which ones go with which adaptations? What is the shirtless guy and the woman demonstrating? I'm assuming the hypothalmus picture is for sweating? Missing one image for one adaptation?
ReplyDeleteGot it. Thank you.
