The term “ethology” is based off the Greek word ethos, which means character. It was first made popular in 1902 by William Morton Wheeler, an American myrmecologist, but the term was...

Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric...

Zooarchaeology is the study of animal remains including shells, bones, hides, scales, DNA, chitin, and hair. Shells and bones are most frequently studied because these do not decay at a fast rate, but most remains do not survive because they break or decompose. In eastern areas of North America, Zooarchaeology developed over three periods. The first, known as the Formative period, occurred in...
