Concept explainers

The history and science of origin and evolution comprise two events, the beginning of life and expansion of life. Our earth originated about 4.5 billion years ago. The term evolution is derived from two Latin words and means the act of unfolding or unrol…

Cladistics

Cladistics is a technique in the classification of organisms, where they are grouped into different clades. The proof for the relationships that are hypothesized is based on the shared derived characteristics known as synapomorphies. These characteristic…

Outgroups

Outgroups are significant in studying cladistics or phylogenetics (that describe the evolutionary relationship between different organisms). Further, it is also important to understand the differences and similarities between different organisms.

Taxonomy

It is the branch of biology that works with the identification of organisms at first, then naming, and classification of them into phenetic or phylogenetic groups (a classification system). In other words, it is the scientific study of biological diversi…

Phylogenetics

Phylogenetics is the scientific study of how various groups of organisms are related at the evolutionary level. It finds the relationship between various organisms based on their evolutionary similarities and differences. It is a part of the taxonomy. Al…

Students have asked these similar questions

How is a species identified by name? A one-part name with the genus A one-part name with the species names A two-part name with the genus and the species names A two-part name with the species names and the genus

Did any of these species increase in number and what could account for this increase? (Everything is in there, there is no missing information, it is based on the data)

According to the morphological species concept, would you classify benthics and limnetics as A) a single species B) separate species C) the species status is not clear according to this species concept. Explain in 2-3 sentences. (I think the answer is separate species, not sure how to explain this...)
