Spanish Scientist Suggests Ancient Egyptians Chewed Narcotic Plants

A Spanish researcher suggested that ancient Egyptians chewed narcotic plants after spotting sexual dimorphism in ancient Egyptian skulls unearthed at the Montuemhat necropolis (TT34), in the Assasif region, in Luxor (southern Egypt).

Sexual dimorphism is the systematic difference in form between individuals of different sex in the same species.

Researcher Jesus Lopez, from the biology department at Madrid’s Cantoblanco Universidad, conducted a study involving skulls of 43 women and 41 men.

He found that men had a very wide face, while women had remarkable differences in their zygomatic arch (cheek bone), a bone extending forward from the side of the skull, over the opening of the ear. The zygomatic arch plays a key role in the masticatory system.

In his study published in the latest issue of the Journal of Anthropological Sciences, Lopez seemed surprised to spot differences between men and women faces, but he ruled out a link between these differences and nutrition as both genders consumed the same food.

“You should look for other activities that are not necessarily linked to food; it’s probably related to the mastication system. It could be the mastication of qat and betel (an addictive plant with tobacco-like characteristics), or the use of the mouth as a third hand in some functions,” he told Asharq Al-Awsat.

Lopez also spotted significant fragility in the occipital condyle, the point which connects the head and the spinal cord. This case was widespread in both genders, even in young skulls, but mostly among women, which suggest that both women and men used their heads for work.

“Images from ancient Egypt depict women carrying heavy loads on their heads. Today, we see the same scene in many countries, where women carry loads on their heads, making a lot of efforts to maintain their balance, while performing other tasks. We found the same effects in the skulls of men, which suggests that men also carried heavy loads although this isn’t depicted in ancient Egyptian images,” Lopez explained.

“We cannot differentiate the types of loads, but we know they were heavy,” he added.

Egyptologist Bassam al-Shamaa rejected Lopez’s allegation about the narcotic plant mastication.

“I agree with the Spanish research’s interpretation on the fragility in the occipital condyle based on images showing men carrying heavy loads on their heads like women, but the use of the mouth as a third hand should be the only suggested reason behind differences in the zygomatic arch,” he told Asharq Al-Awsat.

“We have clear evidence from images engraved on temples’ walls that ancient Egyptians used their mouth as a third hand in some professions including shoe manufacturing,” he added.

Eggs are less likely to crack when they fall on their side, according to experiments with over 200 eggs.

What does this mean for the best way to crack an egg for breakfast? Not much, since a break around the middle is the best way to get the golden yolk and runny whites to ooze out.

But scientists said it could help with hard-boiling eggs in a pot: Dropping eggs in horizontally may be less likely to cause a stray crack that can unleash the egg's insides in a puffy, cloudy mess.

It's commonly thought that eggs are strongest at their ends — after all, it's how they're packaged in the carton. The thinking is that the arc-shaped bottom of an egg redirects the force and softens the blow of impact.

But when scientists squeezed eggs in both directions during a compression test, they cracked under the same amount of force.

"The fun started when we thought we would get one result and then we saw another," said Hudson Borja da Rocha with Massachusetts Institute of Technology, who helped run the experiments.

The researchers also ran simulations and dropped eggs horizontally and vertically from three short heights up to 0.4 inches (10 millimeters).

The egg result? The ones dropped horizontally cracked less.

"The common sense is that the egg in the vertical direction is stronger than if you lay the egg down. But they proved that's not the case," said materials scientist Marc Meyers with the University of California, San Diego who was not involved with the new study.

Scientists found that the egg's equator was more flexible and absorbed more of the energy of the fall before cracking. The findings were published Thursday in the journal Communications Physics.

Eggs are also usually nestled top-down into homemade contraptions for egg drop challenges as part of school STEM projects, which partially inspired the new study. It's not yet clear whether the new results will help protect these vulnerable eggs, which are dropped at much loftier heights.

It's a bit counterintuitive that the oblong side of an egg could hold up better against a tumble, said study co-author Tal Cohen with Massachusetts Institute of Technology.

Countless broken eggs show "the courage to go and challenge these very common, accepted notions," Cohen said.
