The Origin of Life Upon Earth

10 Comments

Deoxyribonucleic acid (DNA) is most likely not the first building block of life because of its complicated double helix pattern. Ribonucleic acid (RNA) is also statistically unlikely because although it is only half as complex as deoxyribonucleic acid being that it does not resemble a double helix structure, but rather a single helix structure, it would have required 5 specific sugar molecules to spontaneously bind together, one by one, in a very specific order. Threose nucleic acid (TNA) however, would only require 4 identical simple sugar molecules to spontaneously, come together. This is theoretically the most probable candidate for being the first spark of life. Threose nucleic acid can easily base pair and exchange genetic information with ribonucleic acid making it the best blueprint which would have shown up long before the complex cellular machinery, which is found within all living cells today

The 4 Primary Preservative Agents Used During Ancient Egyptian Mummification

Leave a comment

The 4 main chemicals used by the Ancient Egyptians for mummification were natron as a drying agent, palm wine to cleanse the body and its cavities after organ removal, cedar oil to anoint, and bitumen as a glue. Natron is a naturally occurring mineral mixture primarily composed of sodium carbonate decahydrate and sodium bicarbonate, with traces of sodium chloride and sodium sulfate, and is harvested from dry lake beds (e.g. Wadi Natrun etc.). Natron’s high alkalinity and hygroscopic properties allow it to desiccate human remains by drawing out moisture, whilst simultaneously inhibiting bacterial growth and chemically breaking down lipids. Beyond preservation, natron also symbolized ritual purification and was used ubiquitously within Ancient Egypt (e.g. religious ceremonies, glass manufacturing, personal hygiene etc.). Palm wine, a fermented beverage comprised of the sap of date palms, was highly valued for its antiseptic and moderate alcoholic properties throughout history within Egypt. During mummification, wt/wety (pronounced “weh-tee”) the Ancient Egyptian term for “embalmers”, used palm wine to rinse the thoracic and abdominal cavities, ensuring that residual organic tissue was sterilized and virtually all odors eliminated. This cleansing was often accompanied by aromatic herbs and spices, believed to be used for both hygiene as well as ritual purification, reflecting the Ancient Egyptian ideological concern for both physical preservation and symbolic purification of the vessel for the soul. Cedar oil, a bit of a misnomer as it was often derived from juniper or other closely related coniferous tree sources rather than the cedar tree itself, was prized for its resinous, aromatic, and antimicrobial characteristics. Cedar oil was applied as an anointing oil to both the skin and the ḥbsw/ḥebesw (pronounced “heh-bes-oo”), which means “bandages” in the Late Egyptian language, but more literally translates to “wrappings”, both to soften and preserve tissues but also to imbue human remains with the fragrance of soil/wood, smoke, and camphor; scents associated with the pantheon of Egyptian deities. For those who could not afford this preservation method, cedar oil could be injected into the body cavity directly, in which its solvent properties dissolved soft tissues, leaving only skin and bone once the natron had absorbed the liquefied remains, raised the overall pH level to halt decomposition, and dried the cavity completely. Lastly bitumen was used, a naturally occurring petroleum product also referred to as “natural asphalt”, which was a black, viscous substance sourced from various geological deposits within the region (eg. the Dead Sea etc.). Although not universally used throughout all dynasties of the Ancient Egyptian state, bitumen became increasingly common in the most recent phases of Ancient Egyptian history, particularly during the Greco Roman period from 332 B.C. – 642 A.D. Bitumen’s adhesive and waterproofing capabilities allowed it to bind wrappings and seal the body shut, and its dark coloration may have been deliberately chosen to evoke Osiris, the Ancient Egyptian god of the underworld, often depicted with black skin and symbolizing both fertility and rebirth. Additionally, in terms of chemical composition, bitumen provided durability to the embalming balms used, with modern day analyses revealing it was typically blended with resins, lipids, and waxes rather than used in its most pure form

The Reason Giants Cannot Physically Exist Upon Earth

If volume and weight are both calculated as 1 unit, when a cube is made 1 x 1 x 1 when accounting for its length, width, and height, and 1 when accounting for its weight, the entire cube is in equal proportion; a concept referred to as a “unit cube” called as such because each of its dimensions (e.g. height, width, length etc.) are 1 unit in length. This changes however when doubling the cube in size and weight. When doubling the cube to 2 x 2 x 2 when accounting for its length, width, and height, the weight does not move in lockstep, because it becomes 8x (2 x 2 = 4 x 2 = 8). This fundamental mathematical principle referred to as the Square Cube Law, explains why as animals become bigger on land, life becomes exceedingly difficult because of the need to maintain and support the large weight associated with such large stature. As animals become more massive, the effect of gravity places an increasing role in their lives. The shape and form of the body is forced to change. Bones become more massive to scaffold their large bodies. This is why the largest animals on the planet are found within the Earth’s oceans as being within water is a way to circumvent this outcome and helps explain why as animals become larger upon land, life becomes exceedingly difficult because of the need to maintain an appropriate structure and weight associated with such large sizes. This principle also explains why the concept of a giant (e.g. mythology etc.) is physically problematic as if a human being were scaled up proportionally to twice their normal height, their volume and weight would increase 8x, whilst the strength of their bones and muscles would not scale at this same rate. The result would be a life form whose own mass would overwhelm its skeletal structure, making movement, balance, and even basic survival virtually impossible without some form of environmental and/or structural intervention and compensation

The Fermentation and Manufacturing Process of Ancient Roman Garum (Fish Sauce)

Leave a comment

The Ancient Roman’s created a special fermented fish sauce called “garum”. Garum was highly valuable and in modern times accounting for inflation, garum would cost $1250.00 for 1 liter. Garum was made from nothing more than salt and decayed fish. The original preparation is unknown as the ancient recipes have been lost. The fishes organs and digestive fluids help in the fermentation process. The container which the garum is made in is left in the sun for a few days to allow the process to ferment as much as possible. The oily slush oozing from the fishes organs and digestive enzymes is the garum and it is loaded with nutrients and contains glutamate which triggers chemical receptors on the tongue to make the brain crave more of it. Glutamate is the primary ingredient/component in monosodium glutamate, commonly abbreviated as “MSG”, and is used by many chefs all over the world

The Reason Human Beings Evolved to Become Bi-Pedal

Leave a comment

There is evidence that between 6,000,000 – 10,000,000 (6 million – 10 million) years ago, grasslands expanded across landscapes, creating vast open savannas, whilst tall grasses continued to remain dominant within wetter environments. These novel environments influenced the movement and adaptation of early human beings. It is theorized by scientists that human beings walked out of these evolving landscapes and adapted to the ground as humans were not evolved and/or adapted to take advantage of tall grasses the way other species are (e.g. snakes, mice, large cats etc.). It is also theorized by scientists that human beings needed to stand upright because the forests around them were thinning and with that, the canopy disappearing, making it virtually impossible to move from treetop to treetop as time moved forward. With the discovery of the hominid Anamensis, it is now clear to scientists that the tree of human ancestry follows its evolutionary order from Australopithecus Anamensis 4,200,000 (4.2 million) years ago, to Kenyanthropus Platyops, to Homo Habilis within the past 2,300,000 (2.3 million) years, to Homo Erectus, and finally to Homo Sapiens, the species to which modern day human beings belong to. Anamensis allows scientists to definitively state that bipedalism occurred 500,000 years earlier than what was previously believed as the tibia bone from Anamensis clearly demonstrates that Anamensis walked upright on both legs

How Plants Produce Food Via Photosynthesis

Leave a comment

If a leaf is magnified 1000x, green bacteria like structures can be observed, referred to as “chloroplasts,” which are packed into virtually every cell of a plant. These chloroplasts behave like bacteria, retaining their own deoxyribonucleic acid, and are only 5000ths of 1 millimeter (0.005 millimeters or 5 micrometers) in diameter. It is inside chloroplasts that photosynthesis occurs. Photons, which are tiny and rapid moving particles of electromagnetic energy (e.g. rays of light), are harvested upon the surface of the plant’s leaves, where they then enter the plant’s cells and are absorbed by the light harvesting complex located within the chloroplasts themselves. It is here that the photon is leveraged to drive the photolysis reaction, which is to split a water molecule and release oxygen, electrons, and hydrogen ions, fueling the energy transfer mechanisms that ultimately convert carbon dioxide into sugars for the plant’s growth and survival

The Caribbean Village of Biological Males Born Without Male Genitalia

Leave a comment

There is a village in the Dominican Republic called Salinas, in which 1 in 90 of the people born are born as males, with testicles, but without a penis, because of misconstrued instructions at birth. In males, the gene on the Y chromosome, specifically the Sex Determining Region Y (SRY), instructs the gonads to become testicles. This leads to the creation of dihydrotestosterone which is a stronger version of testosterone. Dihydrotestosterone transforms the tubercle which all males and females have, into a penis. Females do not make dihydrotestosterone, therefore their gonads become ovaries, and the tubercle becomes a clitoris. Infants perceived as female at birth, due to a lack of dihydrotestosterone during fetal development, later develop a penis during puberty when testosterone triggers penile growth, as it does in typical male development. Those who lack the ability to create dihydrotestosterone, as is the case with those born as males but raised as females in the Caribbean village of Salinas, Dominican Republic where it is common, are technically male, but without a penis, a condition referred to as “5 alpha reductase deficiency”. This condition is quite well accepted in this part of the world and even has a term which is “guevedoce(s)”, (pronounced “guava-doh-chey”) which means “penis/testicles at 12” in Spanish. This condition whilst common in this region of the Caribbean, it is very rare in other parts of the world

The Color of Ancient Egyptian Pharaoh Cleopatra’s Skin

Leave a comment

Cleopatra VII, the last ruler of Ptolemaic Egypt, was of Macedonian descent, which makes her Greek, as her family was established by Ptolemy I, a soldier who later became a General within Alexander III’s military force, a person more commonly referred to as “Alexander the Great”. The Ptolemies practiced interfamily marriage, meaning siblings, or more uncommonly cousins etc., as Cleopatra herself married her brother, therefore her ancestry was predominantly Greek. The caveat to this is that the identity of Cleopatra’s mother is unclear, leaving a lot of room for speculation of potential Egyptian as well as other African or regional influences. As for her skin color specifically, historical depictions and recorded texts do not provide clear evidence, but based upon her Greek heritage, she likely had a light olive complexion, common in persons of Mediterranean lineage during the modern day. Cleopatra’s exact skin tone however remains uncertain without genetic evidence as her remains have never been identified and/or located

The Fallacy of French Emperor Napoleon Bonaparte Being Short in Stature

Leave a comment

Napoleon Bonaparte was not actually short in stature, in fact he was of average height. This misconception stems from paperwork being written about Bonaparte which states that he was 5’2″, written as 5 pieds 2 pouces within France during the early 19th century, but it was from a French town which used an antiquated unit of measurement referred to as the “French foot”, which classified the imperial measurement of 1′ as 13″ instead of the 12″ which is what 1′ is stated to be within the imperial measurement system. When accounting for this error in transcription, it would appear that Bonaparte was actually 5’7″ which during the last half of the 18th and beginning half of the 19th century when Bonaparte was alive, was considered average, or even slightly above average in regard to the stature of height. The fallacy of Bonaparte being short was exaggerated by English propaganda, particularly satirical cartoons which portrayed Bonaparte as small and temperamental, affixing this image to Bonaparte for centuries and into the modern day

The Lush Forests of Australia and Antarctica During the Mesozoic Period and the Reason Antarctica Became Cold

Leave a comment

Both Australia and Antarctica were once fused together as part of the supercontinent Gondwana, neither being an arid and hot landscape nor a cold desert but instead a vast and lush forest, larger than the Amazon Rainforest, spanning thousands of kilometers in size. The reason Antarctica is no longer temperate and forested is because in contrast to most shorelines which disrupt and disperse ocean currents upon contact with the coastline, the waters around Antarctica encircle it unobstructed, forming the Antarctic Circumpolar Current after the Drake Passage opened 34,000,000 (34 million) years ago. Because there is no land to stop this flow of water, it forces the current to become stronger and deeper over time. The Antarctic Circumpolar Current cut the continent of Antarctica off from the warm waters of the north, a thermal isolation further exacerbated by decreasing carbon dioxide levels over millions of years. In a mere 1,000,000 (1 million) years during a rapid cooling phase, although the full shift took tens of millions of years to complete, Antarctica transitioned from an appearance which resembled Australia during its wetter, forested period of the Cenozoic Era, to become a frozen tundra, virtually uninhabitable by humans until the mid 20th century, due to its subzero temperatures which consistently remain far below any other location upon Earth, as well as being locked in by vast ice sheets which formed 14,000,000 (14 million) years ago
