The findings suggest that body preservation wasn't always an accident in 4300 B.C. The hot, desert climate of ancient Egypt was full of dry sand and wind. They built complex structures like the pyramids. They concluded that the ancient Egyptians understood the powerful effects of embalming chemicals in prehistoric times. They held elaborate ceremonies. Since these chemicals do not naturally occur on fabrics, the scientists concluded that the Egyptians mixed these materials together to create a type of embalming agent. The findings suggest that body preservation wasn't always an accident in 4300 B.C. They built complex structures like the pyramids. The mummification process is sophisticated. They built complex structures like the pyramids. They also developed scientific theories for mysteries they could not explain. A team of scientists recently examined funeral cloths from some of Egypt's oldest cemeteries. The scientists put the cloth scraps under microscopes. They found the fabrics contained traces of pine resin, animal fat, plant extracts and natural petroleum. The team was led by Jana Jones, a textile expert from Sydney, Australia, and Stephen Buckley, a chemical archaeologist from the University of York in England.
