Study Notes
Classification Overview
- Classification is the method used to track and organize various types of organisms.
- There are seven major classification groups used today.
Classification Structure
- Organisms are grouped based on shared traits or characteristics.
- The largest classification group is the kingdom, which contains a wide variety of organisms.
- Within a kingdom, groups are further divided into smaller categories: phylum, class, order, family, genus, and species.
- The classification system is often visualized as an upside-down pyramid.
Pyramid Structure
- The top of the pyramid includes groups with more members, leading to less similarity among them.
- As one moves down the pyramid, group size decreases, and similarity among members increases.
- Species occupies the smallest space in the pyramid, representing a single kind of organism.
Organizational Relationships
- Organisms within the same classification group share specific traits with others in their group and higher classification levels.
- For example, members of a phylum share traits with all members of that phylum and kingdom.
- Members of a class share characteristics with their phylum and kingdom, while order members share traits with class, phylum, and kingdom members.
Comparison of Groups
- Members of a family are more similar than members of an order.
- A phylum contains more members than a family, while a genus has fewer members than a family.
- A family has fewer members compared to a phylum, but a genus has even fewer members than a family.
Domains and Species
- The group with the most members is the domain, while the group with the least members is species.
Linnaeus' Contributions
- Carl Linnaeus developed not only a classification system but also a naming system for organisms known as binomial nomenclature.
- In binomial nomenclature, each organism has a two-part scientific name consisting of a genus name (first part) and a species name (second part).
- The genus name is italicized in scientific writing, while the species name is not.
Scientific Names
- The scientific name for humans is Homo sapiens.
- The scientific name for wolves is Canis lupus.
- The scientific name for dandelions is Taraxacum officinale.
