These Old Walls Can Speak Wupatki National Monument preserves dozens of ancestral Puebloan villages. Though silence reigns today, this place was once a bustling hub of trade and life. People of the Northern Sinagua, Cohonina, Kayenta, and Hohokam archeological culture groups planted corns, beans, squash, and cotton among these seemingly barren hills and washes. Where many now see only dirt and hear only wind, ancient Native American people lived, raised children, and thrived. Wupatki is not as silent as it seems. Walls can talk, and if you linger long enough to listen, these teach many lessons. |

Only a couple of fallen fruits would be enough to get a primate ancestors ‘drunk as a monkey’. Instead of being metabolized, most of the alcohol from the fermented fruits would wind up directly in the blood stream, intoxicating the animal and making it an easy prey. Those primates that bore mutations that allowed them to metabolize more alcohol could eat more fruits without exposing themselves to any additional danger. Because they had more resources at their disposal, these primates were more likely to survive hence they the genes were selected and passed down to the human lineage we know today.
Our early ancestors first metabolized alcohol 10 million years ago, a find that helps shape primate evolution
Have you ever wondered why you crave for a drink from time to time or why you can drink alcohol in the first place, for that matter? Our ability to ingest and metabolize ethanol can
Our early ancestors lived mostly in the trees. Once they began to live on the ground as well, they naturally ingested food fallen from the trees as well. Unlike the fruits hung up in trees, the fallen kind is exposed to bacterial degradation, which converts sugars into alcohol.
