They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.
The ancient Egyptians mummified an abundance of cats during the Late Period (664-332 BC). The overlapping morphology and sizes of developing wildcats and domestic cats confounds the identity of mummified cat species.
What explains the genetic relationship between Egyptian cat mummies and modern domestic cats?The study reveals that two of the three analyzed cat mummies contained mitotype sequences similar to modern domestic cats, specifically mitotypes C and G, indicating a genealogical link.How did morphological analysis contribute to identifying species in cat mummies?Morphometric analyses indicated a range of sizes and growth metrics among mummified cats, complicating definitive species identification due to overlapping characteristics.When did ancient Egyptians begin the practice of cat mummification?The first indication of cat mummification dates back to approximately 1350 B.C., associated with burial practices of beloved pets.
Scale development and validation are critical to much of the work in the health, social, and behavioral sciences. However, the constellation of techniques re...
