Archaeology
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. The discipline involves Survey (archaeology), surveying, Archaeological excavation, excavation, and eventually Post excavation, analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. A ...

Fountain Darter
The fountain darter (''Etheostoma fonticola'') is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the Family (biology), family Percidae, which also contains the perches, Gymnocephalus, ruffes, and Sander (fish), pikeperches. It is found in the headwaters of only two rivers in Texas, United States, the Comal River and the San Marcos River. It is generally smaller than long and feeds on small invertebrates. It is a federally listed endangered species of the United States and is also listed as endangered by the IUCN. Distribution and habitat The fountain darter is known from only two locations, primarily the headwaters of the spring-fed San Marcos River, having been observed as far as 1.25 miles downstream, as well as the upper reaches of the Comal River in central Texas. Its geographic isolation is reflective of its incredibly specific habitation preferences, which demand conditions that can only be found in these two Texas river headwat ...
