Battle of the Sexes: Men vs. Women on Vision


As an educator I am always the first to admit that my students teach me as much as I teach them (or at least hope to teach them), and this post is one of those examples as it is inspired by information that one of my Fall 2018 Introduction to Anthropology students shared with me.  I promised that student that I would look into this matter further as I was unfamiliar with it, and, to be honest, I had my doubts as to its legitimacy.  While the semester is now over it is better late than never (another comment I make to students) in regards to finally looking into the matter: do men and women differ biologically in regards to vision, and if so, to what extent?


Figure 1: Color vocabulary differences by sex/gender (Source: Ayman, 2017)

Anthropologically, we know that culture does play a role in the degree to which an individual recognizes color (Figure 1).  My dad jokes that my stepmother does not like going shopping with him because he never gets the colors right when she asked for a new article of clothing to try on (e.g. “Can you get me the magenta blouse?” and my dad returns with the maroon one).  At least in American (and many Western) culture(s) we can easily see these subtle color differences by looking at the color choices available in men’s versus women’s clothing (or for a real challenge, try picking out paint colors with someone of the opposite sex-note, not an exercise for the faint of heart).  Other studies have demonstrated that other cultures who put less emphasis on color differences (as evidenced in the lexicon of their language) there will not be a stark difference between males and females when it comes to color differentiation. 

The cultural differences in color identification are well known, but scholars focused more on biology were concerned about the overemphasis on the role of culture in this matter and sought to evaluate the potential biological contributions to this matter.  Two studies by Israel Abramov et al. utilizing a sample of American high school, college (undergraduate and graduate) students, and faculty members at Brooklyn College demonstrated statistically significant differences between men and women regarding their abilities to differentiate colors and to identify spatio-temporal variations.  Their research demonstrated that women are better able to distinguish color variations, often times seeing brighter colors than men.  Abramov and team believe this may be related to the fact that color genes are found on the X-chromosome, which could assist women (who have two X-chromosomes) and hinders men (who only have one X-chromosome).  It is well known in biology and medicine that genetically inherited color blindness is more common in men than women because this trait is a recessive one, and the presence of only one X-chromosome in men increase their likelihood of being color blind.  Unfortunately, the researchers could not sufficiently relate the differences in color differentiation to genetics, although their research seems to suggest as much.  They called for additional study on this matter.

Whereas women are better able to distinguish colors men are better able to identify spatio-temporal differences.  In other words, men are able to see color changes over greater distances as well as better adept at noticing movement (as a result).  This difference they attributed to our hominid ancestors and the roles that men and women took-withmen as hunter and women as gatherer.  Abramov et al. claimed that men as hunters would have a greater need to see over longer distances in order to identify potential prey and predators (so they do not become prey), which is a portion of their article that many popular science writers picked up on.  Unfortunately, Abramov et al. noted that these differences developed over time, and that children, particularly very young children, did not appear to have any biological differences that related to this difference between the sexes.  Therefore, it could be that men’s ability to see over greater distances was trained and fostered over time, whereas women, who are often times gatherers not out of choice but necessity (as they are the primary child rearers because women feed the children through breast feeding), would not have received that same level of training.  Therefore, it appears that while there may be some biological differences between men and women regarding this matter culture may account for some of the differences as well.

Ultimately, while we know that there are cultural differences when it comes to recognizing colors among various cultural groups and between men and women there is evidence to demonstrate that there is a biological component to these differences as well.  These differences are slight, but they appear to be culturally fostered, furthering the notion of the roles between men and women.  This overall demonstrates the need to study what it means to be human holistically in order to not fall into the trap that it is either nature (biology) or nurture (social/cultural) that makes any one person into who they are and to realize that it is most often a combination between biology and culture that defines each and every human on earth.

Spotlight on Students: Thinking Like An Archaeologist

Thinking like an archaeologist is one of the most challenging exercises a novice or inexperienced person can do, including beginner archaeologists.  For one of the SA 202: Introduction to Anthropology assignments students were tasked with doing just that.  By viewing the familiar as the unfamiliar they gained important insights into the challenges archaeologists face, and several of them did exceptionally well in the exercise.  Here are a few students work that was eligible and agreed to be published.


By: Makayla Peterman

            It is currently the year 4015, everything is crystal clear, and the light of the stars beam onto our planet, Clypto, in hughes of warm colors. Clypto’s climate is beautiful with a permanent rotation between hot, warm, cool, and cold weather, coordinating with the land having great vegetation and flourishing natural life.  Living on planet Clypto is the only thing I have ever known, but there is strong research, legends, and archeological evidence to prove there was civilization on Earth prior to the modern ice age which destroyed most of the planet. Although Earth once supported bountiful life, it no longer does. Earth only permits travel in the mild parts of the year, since the climate is much too harsh year-round. Getting from Clypto to Earth takes around four hours and 30 minutes by the astronomical shuttle, which is lengthy if you ask me.
            As I approach the potential archeological site in the center of a state once known as Missouri, I can see the decaying figure of what looks to once be a house. The site was under about a foot of dirt that had to be excavated and carefully brushed away. The perimeter is marked by a large square making up some of the walls. The walls are decrepitly thin and only stand about two to three feet tall at this point. Stepping into the rectangular structure, there are remnants of small, black, square tables turned over though out the area next to the extremely old sofa and unusually large chair. On both the chair and the sofa sat square, thin blankets. We have blankets on Clypto, but they are about 10 times the size and much thicker. Inspecting the perimeter more closely, it is clear there is a three-inch-tall band surrounding the base of the walls left intact. The band is composed of a wood mixture with one side neutral and one side white. This excavation site is new, so this information has not yet been discovered by anyone except my team of colleagues and myself.
            While scanning and dusting the site, I find two identical tan plastic plates. The two plates have the same small, circular hole on each short side of their rectangular shape. They are unusually thin, lightweight, and smoothed out. The edges are rounded but still have a sharp point on each corner. In the middle of them, there is another rectangular shape carved out of it. In total, there are two circular holes and one rectangular hole centered on each. I carefully flipped it over to find the words “Made in China” on the back of both of them. I have never heard of China before, but it could be another state such as Missouri. Finding a purpose for these two objects has been deemed impossible, but if we can find more information on China, we may be able to discover what they were once produced for. What could people have used these tiny plastic plates for? The three holes make me believe they would not have been used to eat off of, nor to store anything in, but no one cannot know for sure.
            The second discovery I made was uncovering a black box near the remnants of the sofa. The box is square in shape and there is a different texture on nearly every side. The front has a slot and a button that has a triangle on it, but there is also a triangle with an exclamation point inside underneath the slot. On the right side of front, there is also a white circle with an off centered black X in the middle. There are also the letters HDMI on the front followed by other fine print that was impossible to interpret from the intense weathering. Picking up the object, it was much heavier than the plastic plates but could not have weighed over four pounds. The box has multiple holes in the back, one that looks to be a triangle made up of three circles and the others are only circles. The triangular hole in the back does not match the other holes which is intriguing, what were people putting in these holes? It could be a hiding spot for small objects or even an electronic device, if they had any at the time. Inside, there are multiple wires which proves the electronic theory.
            As we kept scraping away at the past, I uncovered a cone shaped figure. The cone was much wider at the base compared to the peak and it is embellished with white foam and glitter. The foam and glitter was glued to the outside of the green, spiked object. The cone is about one foot tall and looks similar to the yellow metallic cedars that grow on Clypto, so it could be a tree. The cone is made of a mixture of plastic and wire materials, which could mean it was once used as a cleaning device. If it were not used for cleaning, the cone could potentially have a religious affiliation. There is other archeological evidence discovered on Earth that supports the idea that there were diverse religions among the population, so it is likely the tree figure has a religious connection.
            The most interesting artifact I found at the site was a tiny, two-inch-tall triangular, shaped structure attached to a small chain and metal circular ring. The structure has four distinct posts on the bottom that lead together to one sharp point on top, similar to the cone shaped tree. It is made from a solid metal material and has distinct architectural features. On either side of the top of the structure reads “PARIS” and the other side engraved “FRANCE”. PARIS and FRANCE were unheard of until this discovery. After collecting the artifact, I looked up both PARIS and FRANCE on the interweb and learned they were lands like China, from the tan plastic plates. The metal ring attached to the chain allows you to pull it apart in some areas, letting you attach it to things it could fit on. The use for this product was probably for memorabilia and decorative purposes, but one cannot be completely sure.
            Another interesting find is a strand of tiny LED lights attached to a silver metallic wire. In Clypto, LED lights were abolished in year 4000. The wire was very thin and flexible, as if it could be wrapped around something. Along the wire and LED lights, there are small red balls attached with slats on the sides. The tiny red balls have a metal circular object inside that make them produce a highpitched sound when they are moved. At the end of the wire, there is a transparent rectangular box with and ON and OFF switch. In Clypto, there is rarely ON and OFF switches. Inside the box, there are three crescent shapes hollowed out with a tiny spring on each alternating side. I also noticed there was a plus and minus side on alternating sides as well. The strand of loud light up lights would most likely be used as a children’s toy.
            The final artifact I discovered at the central Missouri site was a small, six-inch-long, maroon zippered pouch. The pouch has two distinct sections, probably to hold different belongings. It is composed of a thin, slick, textured material which reminds my team and I of a skin of some kind. The zippers on the pouch are heavy duty and golden, lining the top of each section. On the front of the smaller pouch, there is a solid gold plate with the word “FOSSIL” engraved on it. Fossils are remains of animals, plants, or humans preserved under the surface. This pouch could have been used to store fossils in as they have been found and to keep with you, as it is a small pouch.
            Examining the rectangular site, it measured 863 square feet. This structure was a small size if it were a home, but not impossible to inhabit. If there were a large family living here, it would definitely be an uncomfortable fit, but if it were for only a few people, it could work. With the evidence of the couch and large chair, it is easy to determine this was a home at one time.
As one can imagine, it is a true struggle not knowing the history or uses behind the artifacts found on Earth. Another challenge we faced was the preservation of the artifacts, as they were rotting and decrepit making the researcher more difficult. As I dug up the artifacts, it was virtually impossible to decipher their use and purpose in the home. With limited insight to Earth’s history, it is hard to put a timeline on the artifacts, as there is no written manual for each object. The various challenges archaeologist face when excavating a site is well worth it in the end, with loads of new insights to Earth’s historical values.  Excavating the central Missouri site is an educational process which requires a lot of time and effort sifting through the soil, but it is vitally important to determine our past.

Hello, my name is Talarius Larkinius, and I have recently been exploring the lost City of Jefferson. This is one of the many ancient cities of the United States of America that was destroyed in the Great Series of Earthquakes of 2019. This earthquake led to the destruction of many nuclear power plants, making the land full of radiation. This occurred just before a volcanic eruption that further destroyed the western part of the country and covered the rest of the country in ash. These events wiped out that whole civilization. That was 1000 years ago, and no one has wanted to repopulate the area since. In this City of Jefferson, I had found a very well-preserved room. I was anxious to see what secrets it holds about this lost civilization. 

         Much of the building that this room is located in was destroyed, but this room was well preserved because it was on the second story, so it had nothing falling on top of it when the earthquake hit. There are many rotting wood furnishings in it, but I am not sure what their purposes were. There are remnants of some kind of fuzzy cloth flooring, and the walls are made of a thin, stone like material. Some small parts of the walls still have a bright green color to them. The ceiling is made of the same material, only it is white. There are two archaic doorways with strange round knobs with slits just below the knobs. One doorway is the entry way to the room from the rest of the building, and the other doorway leads to another very, very small room. On one wall, there is a large, rectangular opening that I think was a window, considering the pile of broken glass on the floor under the opening. I find it sad that these people did not have earthquake proof and nuclear disaster proof buildings like we do now. Anyways, here is a general layout of the room. Blue squares are symbols for furnishings.  The building itself is set in an area surrounded by lots of similar sized buildings. Maybe these buildings were dwelling places, since there are so many of them. From what we know about some other civilizations from around the same time, many families or individuals lived in their own buildings. That is very different from today, as most of the civilized world live in mega buildings or compact underground cities.


            There are many artifacts in this room. I would like to document a few that I think have significant meaning as to who lived here, and what life was like in this lost civilization. First is the largest furnishing in the room. It is two feet tall, six feet long, and three feet wide. The bottom half of it is hard, but the top is soft and springy. It is covered in remnants of cloth. The pieces are dirty, but I can see greens and blues. Whoever lived here had a taste for bright colors, or maybe these bright colors had special meanings to the civilization. Since it is about the length of a human, maybe this object was a place to sleep. These sheets of cloth could have covered a person to keep them warm. Perhaps this was a resting room for one person. Lying on top of this furnishing was a fake bear. It was a foot tall. It was very soft, and it was multicolored in soft pastel shades. It had a nose sewed onto in and two eyes, and there was a pink ribbon around its neck. There is also a small artifact that was very striking and unusual to me. It was on one of the walls. It was made of two thin pieces of wood that fit together perpendicularly. It was six inches tall. One of those pieces of wood was slightly shorter than the other. And on top of the wood was a metal figure of a man, who appeared to be hanging from the shorter piece of wood by his hands, and his hands were nailed to it. His feet did not touch the bottom of the longer piece of wood, and they were also nailed to the wood. His head hung slightly hung to the side, his eyes were closed, and he was bleeding from his side. He looked like he was dying. There was a crown of thorns around his head and above his head was an inscription reading “INRI”. Next, there was this plastic thing lying on the floor. It was a plastic frame with rectangular glass pieces in front. Then I noticed something. The glass pieces were positioned to look like human eyes, only a little larger and more rectangular. The plastic frame was attached to two long plastic sticks with curves at the ends. It fit almost perfectly on my head, the two sticks resting on my ears. When I looked through the glass my vision was blurred. Last, resting on a wood furnishing was a metal object. It consisted of two rectangles, and both were 18 x12 in. One rectangle was flat on the wood and had what I think was the civilization’s ancient alphabet inscribed on a bunch of buttons. The other rectangle was standing strait up and had black, soft surface on one side. On the other side, “MSI” was transcribed into the metal. The small room that I mentioned earlier has nothing in it but a bunch of shelves and heaps of old cloth. It was probably used for storage.

I believe this room was the dwelling place of a witch doctor or high priest of some sort, or at least of some religious figure. The bear was on the sleeping place to ward off evil spirits while the person slept because bears are fierce creatures. The bright colors that decorated the room were a symbol of high status. In nature, bright colors on animals sometimes mean “stay away,” and perhaps these colors of the room meant, “Stay away, peasants, I am holier than thou.” Only a high-status person could enter this dwelling place. The meaning of the dying man on the wooden thing could be disturbing. I am wondering if the people of this civilization practiced human sacrifice as a way to appease the gods. This religious figure would have a human sacrifice as a decoration because human sacrifice was part of his/her job. The plastic and glass artifact was an object of high fashion. It made a person’s eyes look bigger. Your vision might be blurred but when another person looked at you, the magnified glass made your eyes look bigger than they really were. As for the artifact with the alphabet on it, it might have been used to communicate with their gods. After some research, I realized this object could emit signals into the sky. However, before I accept these guesses as fact, I will have to study many of the buildings in this city to learn more about this civilization. There is much more to explore than just one room.

            These are just some of the many things people in the future could think about our civilization if archaeologists get things wrong. We cannot blame them, though. There are some obstacles archaeologists face that are hard to get past. One is that people tend to look at another civilization through their own cultural lens. Sometimes it is hard to stay objective and open when someone discovers something that seems very strange or even creepy to us, like the Nkisi dolls (Power Figure). There is also the language barrier. It is hard to learn a lot about a civilization when you cannot decipher their writing, or if the civilization had no written language at all. These things can lead to great misunderstandings. We have to be careful when we make assumptions about people of the past.
