The vestigiatores were a group of animal trackers and the ursarii were bear-hunters. [161] Other forms of public entertainment involving animals in the classical world included theriotropheia and leporaria, which were further examples of animal pens, as well as the piscinae (early aquariums and fish ponds) and walk-through bird aviaries.
List of first human settlements. This is a list of dates associated with the prehistoric peopling of the world (first known presence of Homo sapiens). The list is divided into four categories, Middle Paleolithic (before 50,000 years ago), Upper Paleolithic (50,000 to 12,500 years ago), Holocene (12,500 to 500 years ago) and Modern (Age of Sail ...
The following tables give an overview of notable finds of hominin fossils and remains relating to human evolution, beginning with the formation of the tribe Hominini (the divergence of the human and chimpanzee lineages) in the late Miocene, roughly 7 to 8 million years ago. As there are thousands of fossils, mostly fragmentary, often consisting ...
As more and more fossil groups were found and recognized in the late 19th and early 20th century, palaeontologists worked to understand the history of animals through the ages by linking together known groups. [20] The Tree of life was slowly being mapped out, with fossil groups taking up their position in the tree as understanding increased ...
The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...
e. In biology, taxonomy (from Ancient Greek τάξις (taxis) 'arrangement' and -νομία (-nomia) ' method ') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic ...
A colony of 48,000 quaking aspen trees (nicknamed Pando), covering 106 acres (43 ha) in the Fishlake National Forest of Utah, is considered one of the oldest and largest organisms in the world. Recent estimates set the colony's age at several thousand (up to 14,000) years, although tree ring samples date individual stems at rarely more than 130 ...
A domain contains one or more kingdoms. Intermediate minor rankings are not shown. In biology, a kingdom is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla (singular phylum). Traditionally, some textbooks from the United States and Canada used a system of six kingdoms (Animalia ...
