Classification is a way to place living things into different categories based on their characteristics and then identify them. This type of system in Biology is called taxonomic classification. It begins with very broad categories and ends with the exact species of the particular organism. ...

In the clade on the left (a), the relict is among the most recent species as indicated by the position on the time axis (dotted line) while in the clade on the right (b), the relict is among the most ancient species. It must be reminded that in most cases with lack of fossil ...
The subject is a member of a small clade of very strange crocodile-line archosaurs (ornithosuchids) from the Triassic period. They have a long history (>100 years) of study and ideas about them have roamed widely, such as what they were more closely related to (theropod dinosaurs? No. ...
My first scientific publication (in 1998) came from rummaging through the UCMP museum collections as a grad student and spotting an obscure pelvic bone that turned out to be highly diagnostic for the equally obscure clade of bird-like dinosaurs called alvarezsaurids. I happened to open that ...
Root and Clade Furthermore, a few trees have a basal node known as the "root" of the tree. Then here comes the "Clade," commonly known as the "ancestor" of all the species branching out. Strengths and Limitations of a Phylogenetic Tree ...
While extant cervids are clearly characterized by the unique traits of these cranial appendages like their branched structure, their burr and their regenerative nature, the origin of the clade and antlers respectively has a long tradition as an issue. The fossil record of antlers is excellent, ...
The most inclusive clade containing Ankylosaurus magniventris but not Stegosaurus stenops. About Ankylosauria is a group of Middle Jurassic to Late Cretaceous-aged thyreophoran ornithischian dinosaurs, whose members (ankylosaurs) are affectionately known as tank dinosaurs because of their wide, low...
What is serial homology in the phylum Annelida? Phylum Annelida: The phylum Annelida is better known as segmented worms. If you think of an earthworm, an organism many people are familiar with, you will note the series of indentations that make the worm look like it is made of a long ch...
What is deme in zoology? What are taxa in biology? What is invertebrate zoology? What is protogyny in zoology? What are coacervates in zoology? What is an example of a mold fossil? What is the clade Xenarthra? What is the scientific study of amphibians and reptiles called?
