What Makes A Guy An Eye Candy?

Posted by Dyamond Logan in Science and Society - Best on Monday, November 15, 2010 at 10:01 am

The attraction between a male ad female seems to always be a question well answered. However, I decided to focus on what actually makes a female attracted to a male. Is there an actual scientific reasoning behind it or is off of self judgment.  Could it be the way a male walks, or presents himself that makes a female attracted to him.

Through a study found from the book "human physique and sexual attractiveness in men and women" I had found that women like men who are tall, who have slightly narrow waist and broad shoulders. Men who are athletic and have well toned muscles are more preferred because it symbolizes they are more likely to be a good hunter, which could mean they could provide for their family. With males being big and strong they can protect the family from other males and danger. Women are also attracted to male that are successful because it shows that males have the ability and resources to be able to provide for the family 

In conclusion, just like males, females are cautious about the male they choose to mate with because women believe that men have the most valuable reproductive resources to offer. Men produce thousands of sperm while women only produce about 400 eggs in their lifetime. The time of pregnancy and child bearing are long process which puts more pressure on what women find attractive about guys. They find the security and long relationship to be attributes that make the guy more attractive. In other words a women finds a man that can provide for them, will stay there for a long period of time, and will be able to protect them. Kind of the same things we need in society today to survive.

Evolution of Hair: Why are humans in comparison to other mammals, not completely covered in hair?

Posted by Alexis Ukaha in Science and Society - Best on Friday, November 12, 2010 at 11:48 am

Humans are known to be of a complex species, however it is no mystery that Homo sapiens (humans) are also categorize as mammals. There are many components and characteristics that define a mammal; hair being on of them. Epidermal in origin, hair is made up of a complex structure. Mammals are the only animals in which hair is found on. Even "hairless" mammals, such as pigs, elephants, dolphins, and other cetaceans (another word for marine mammals) are partially covered with fine short hairs. Hair has many functions within itself. The many functions of hair include the retention of heat, attraction of mates, protection of skin, sexual dimorphism, an absorption of sunlight and, in the case of pets, the elicitation of a protective response from humans (us). Now how is it that humans and animals, all mammals, differentiate in how the hair is actually presented on their bodies? Though humans are covered in hair completely, they are not covered to the extent that animals are. This is because mammal body hair is an evolutionary enigma.

The common belief of hair evolution is that hair evolved to help retain body heat since hair is an excellent heat insulator. But there is no conclusion as to which evolved first: hair or warm-bloodedness (endothermy). Researchers verbally combat between the two all the time. Most ‘Darwinists’ believe that humans evolved in Africa along with other primates, all of which were almost totally covered with thick fur (again, hair). As such, a common view is that now the body hair of men and women are purely vestigial, a useless evolutionary leftover from when we were ape-looking animals. Initially hair arose as surface insulation, retaining body heat in primitive mammalian endotherms.

The reason for the putative issue of human hair loss in evolution is still unknown, and all the explanations and reasoning proposed are contradicting.

What evolutionary advances have enabled humans to be able to write/communicate?

Posted by Sabria Brown in Science and Society - Best on Friday, November 12, 2010 at 8:01 am

Over the years writing has been a tool people would use to communicate with others. Where did writing come from and how does it have an effect on humans now. It started from roman numerals, which were carved in stone they were backwards and interpreted in this way to many who wrote it. [1]. Over time had passed the writing got thicker and started to look very script. By the 5th century there were capitals, this was a different direction from where it started and added a different style to writing. [2]


During the writing, pictures started to form. They began from the Egyptian hieroglyphics. Many other religions had their own ways of writing and eventually this later led to Cuniform, Chinese pictograms and also Mayan glyphs. [3] People could communicate in their own writing. The only pondering thought left is how was the writing for communication revolutionized over time? The answer  might be that over the years writing is changed in put into different arrangements because it revolutionizes itself. The process of writing is still going on and who knows when it will end. Writing is a form of evolution. [4]

The Evolution of Obedience

Posted by Danielle Duncan in Science and Society - Best on Friday, November 12, 2010 at 8:00 am

Evolution of Obedience

  Think 81 years ago, on the island of Bathurst off the coast of Australia Indigenous Australians hunting and gathering, daily struggling to survive.  As a child you a born into poverty, famine, and danger, dealing with animals and an environment that could take your life.  In your first few years, all you know is your family, your mother, who birthed you, your father who protects you, and your elders who support you, who else would know better how to survive.  Underneath these selection pressures, children who would not obey, would die, so obedience as a trait survived. 

            Other hostile environments in different areas instill obedience to a degree of loyalty, trust and brotherhood.  In war torn areas children are recruited from young to join rebel militia.  They pillage through villages stealing people’s children, killing children who seize to obey.  Obedience is pounded into their mind from young, and if that trait does not sustain, eventually the child will be killed.

            Even as adults in a modern society obedience to authority prospers.  When you disobey the law, you go to jail, loose connections with the world, and are unable to procreate with the opposite sex.  Adults, who don’t obey the “rules” loose their job, loose their house and suffer fines and penalties, which are unpleasant. 

 

Future Questions?

If the government becomes lenient with there laws will that create more disobedient children?

Does being disobedient or rebellious make you more attractable?

How Did The Human Eye Evolve?

Posted by Jennifer Albright in Science and Society - Best on Friday, November 12, 2010 at 7:48 am


Human Eye
Human Eye

The most commonly used argument against Darwinism and for Intelligent Design is the human eye and it’s complexity. How did the human eye evolve? How does this change the strength of the argument of Intelligent Design as a scientific theory?

There are currently two competing theories as to how life on Earth came about, Darwinism, evolution and natural selection, and Intelligent Design, some great architect creating life. The most promising evidence for Intelligent Design had been the human eye and the argument that the independent pieces (the retina, lens…) had to have come about all at once for organisms to see. However, scientists have a theory as to how the eye evolved, creating a disturbance in the most prominent argument of Intelligent Design.

Diagram of Evolution of the Human Eye

Here’s the theory for the evolution of the eye: the original “eye” was a collection of cells on the skin (that curved inward like an eye socket) that helped organisms to “see” light, helping it to “see” if any other organism was in that direction because of the break in the light that the organism saw. Eventually the amount of light that the cells could detect was narrowed to give organisms better direction. And from this the cells became a retina, which helped the organism see even more clearly. Finally, the eye grew a lens that helped the organism to see even more clearly. We can even see these different stages of eye development in living species today.

And so, due to evidence of the evolution of the human eye, Intelligent Design loses its most promising argument. If there had been any disagreements as to whether Intelligent Design was a scientific theory, we now see that by ripping apart it's best argument it leaves us with a new term for creationism.

What is the difference between a myth and a theory?

Posted by Rachel Patterson in Science and Society - Best on Friday, November 12, 2010 at 7:45 am

 What is the difference between myth and theory?


White_square_with_question_mark

 

            This is the question that has been bothering me for the past month.  If the theory of evolution is so troublesome to the school district, why aren’t greek myths?  Is it not true that both Greek myths and the theory of evolution deal with the theme of how life was created? Could they both not potentially influence student views on creation? What makes them so different?

 

            After much research, I have discovered that a myth can be apart of a theory. Myths are stories that are created as an explanation for why certain things exist.  These tales date back to the early history of people.  A theory can be used to explain why myths exist all over the world.  There is actually a theory known as “The Jesus Myth Theory” that poses the idea that Jesus of Nazareth was not a historical person, but a fictional character or mythological archetype created by early Christians.  The idea that Jesus was not real but was a fictitious figure is apart of a larger theory that explains this myth. 

 

            According to Religion Compass, “Myths are prose narratives which, in the society in which they are told, are considered to be truthful accounts of what happened in the remote past.”  Theories serve to explain why these myths are created.  However, myth theories that are taught in school, such as the Greek myth of Zeus, are taught in such a way that makes it obvious that the stories are fictional.

Questions to Consider:

•What about a theory makes it controversial?

•What other factors separate the theory of myth and the theory of evolution?

Why Are Humans Smarter Than Chimps if We Have the Same Common Ancestor?

Posted by Kellam Farrell in Science and Society - Best on Friday, November 12, 2010 at 7:42 am

(Find this image here)

Evolution is a complicated process, but it basically happens like this. When one species separates into two groups and eventually turn into two different species is what is called speciation. As these two groups acquire different traits from each other, they are going through what is called natural selection which they go through in order to adapt so they would be best fit to live in their environment. When these two groups have finally become different species, they have evolved. A perfect example of this is from looking at a certain kind of bird that has two different kinds of traits. One group of this bird lives in the west and is white. The other group of this bird lives in the east and is black. Right now, they are a part of the same species, but since they do not mate with each other and live in different locations, they will eventually become two different species because they will be passing different kinds of traits on to their offspring.

(This image gives an explanation to natural selection. Find it here)

This is what happened with humans and chimps. What I want to know is if humans and chimps evolved from the same species, why did humans become so much smarter than chimps? A long time ago, humans and chimpanzees were the same species. Lets call this species A. It is likely that species A had more chimp like traits than human like traits. Nobody knows for sure, but it is probable that the reason why humans have become so much smarter than chimps is because humans have had more changes in traits from species A than chimps have. It is likely that when species A was separated, the group that evolved into chimps did not move to a highly different environment from where they already lived and the group that became humans moved far away and they were required to have bigger brains in order to survive in their new environment.

Why do men have nipples?

Posted by Christopher Cassise in Science and Society - Best on Friday, November 12, 2010 at 1:02 am

Rough draft better

Chris Cassise

Why do men have nipples?. It’s the kind of question that doesn’t need to be answered but should be interesting to find out why they are there. It’s understandable for women to have nipples because it is the distributor for the breast milk to feed a newborn baby but a man, what does he need it for? According to Darwin’s theory on natural selection, it is theorized that men shouldn’t have nipples because during natural selection, the undesirable traits in the male/female body gradually lose their parts they don’t need over time. This would make sense as to why men have nipples; the process must not go through natural selection obviously since there must be a significant reason for it being there. A great example was the appendix, which now a useless part of our bodies was a part of the digestive track making it significant component. [1]

Men have nipples because it follows part of a female template since both sexes have similar tissue and body parts. Since this is confirmed that we share parts, it isn’t hard to understand why men just have nipples. When breasts grow abnormally on men it is called gynecomastia, which is the enlargement of breasts. So the question is simple surprisingly, Men and women follow the same template and nipples are just created no matter what sex you are and the chromosomes figure out if they will be functioning or non functioning in the process of knowing if they are going to be a man or woman. Its the effect of genes, in which the Y chromosome and hormone testosterone that changes the embryo. The idea of shared genetic basis of two traits is known as genetic correlation. Genetic correlation is “the proportion of variance that two traits share due to genetic causes.”[3] The evolutionary default is for males and females to share characters through genetic correlations.[4] Testosterone promotes the growth of the penis and testicles in men and since nipples are there before this process begins, they inhabit. Some genetic scientists have noted through this article that if nipples were harmful for the male body, they would have disappeared over time.

The Addictive Personality.

Posted by Aidan Jamison-Frank in Science and Society - Best on Thursday, November 11, 2010 at 11:23 pm

It has long been asked if there is such thing as an Addictive Personality. As you’ve grown up perhaps you’ve noticed some of your friends have become dependent on substances like caffeine or nicotine. But is this just a personality trait, or something more? Research has shown that it could be rooted in one’s DNA. According to research done at the University of Utah, an ‘addiction gene’ wouldn’t mean that someone is bound to become addicted, but rather “it may be harder for people with certain genes to quit once they start.”  

In recent studies, and Alcoholic gene, DRD2, “was present in more than two-thirds of 35 deceased alcoholics, whereas it appeared only in one-fifth of 35 deceased non-alcoholics.” This confirms that if a parent is an alcoholic, it is more likely for their children to be alcoholics as well.  According to Web MD, the genetic trait is considered a deficiency. It seems to have no contributing factor to our species survival. Additionally no scientist has presented a strong theory on why the gene developed in the first place, beside it being a random genetic mutation.

 In the same way that the 'Fat Gene' shouldn't be a scapegoat for obesity, the 'Addiction Gene' shouldn't allow the addicted to use this as an excuse for their condition. There is, of course, no cure for our own genes. The only thing that can be done is to avoid easily abused substances in the first place.

Evolution of Venomous Snakes

Posted by Bria Wimberly in Science and Society - Best on Thursday, November 11, 2010 at 11:00 pm

            There are many types of venomous animals like the lizards, scorpions, even snake_mainthe male duckbilled platypus. But my main focus for this blog are snakes. There are more than 2,200 species of poisonous and venomous snakes in the world. Snakes lost both arms and legs due to grassy and subterranean habitats, but evolution has handed snakes the ultimate weapon: venom. How did they evolve into venom-injecting beast and how is venom still evolving into society today?
            Snakes emerged during the Cretaceous period from lizards, but Dr Bryan Grieg Fry at the University of Melbourne believes, "that almost all snakes share a common, venomous, ancestor". Venomous snakes have similar classes of protein in their venom, suggesting that in the vast difference of habitats, snake’s venom derived from a common origin.

Venom itself also evolved, its toxins and rattlesnake_02tfkproteins being reborn from other proteins in tissues throughout the snake’s body. snake-venom toxins were derived originally from proteins in the brain, eye, lung, heart, liver, muscle, mammary gland, ovary and testis. By tweaking the proteins from other body tissues, snakes developed a way to create more specific and highly potent toxins.

Venom is still evolving today in medicine, having a beneficial effect on the body. For example, some poisons reduce blood pressure so quickly that the victim dies. But by changing and reproducing some components in venom, scientists can make a drug that reduces blood pressure.


Further Questions:
What other types of medicine can venom be substituted in?
Did venomous and poisonous snakes also evolved from the same ancestor?
Which venom is the most potent?
