We can thank the majority of human history for giving science the ability to examine the human skeleton, and its decomposition process. But recently — meaning within the last century — funeral and burial practices have changed drastically, altering the way we see the dead. It turns out that these practices, which include embalming and cremation, have made the decomposition process more mysterious. That poses a problem for forensic law enforcement teams, whose technology has become more advanced but are still unable to determine how long an especially decomposed body has been around for.
That’s where Texas State University’s “body farm,” near San Marco, Texas, comes in. Run by the university’s forensic anthropology research team, it’s one of only five in the world (all in the U.S.), and is the final resting place for about 50 bodies at any given time, Vox reported. Researchers at the farm are tasked with analyzing the decomposition process from beginning to end. Some bodies are placed under cages to prevent vultures from scavenging, but others are left out in the open for them to go to town. Others, meanwhile, are put in the shade while some are left out in the sun.
