Study Notes
Taxonomy
- Definition: The science of naming and classifying organisms.
- Provides a standardized way to refer to species, facilitating communication among scientists about living things.
Taxa and Classification
- Taxon: A group of organisms in a classification system.
- The hierarchy in the Linnaean system consists of 7 levels, with each level being nested within more general categories.
Binomial Nomenclature
- A system that assigns each species a two-part Latin scientific name, enhancing clarity and specificity.
- The first part represents the genus and is always capitalized and italicized; the second part, the species descriptor, is lowercase and also italicized.
Genus and Species
- Genus: A collection of physically similar species that are closely related, such as Quercus for oak trees.
- Species is the basic taxon in Linnaean classification and refers to organisms that can breed and produce fertile offspring.
Levels of Classification
- Linnaean classification levels, from highest to lowest: Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Mnemonic to remember levels: "King Philip Came Over For Great Spaghetti."
Classification Focus and Evolution
- Linnaeus’ system emphasizes physical similarities for classification.
- Convergent evolution explains how unrelated species can develop similar traits.
- Genetic research is increasingly used to classify organisms, as it provides insights into evolutionary relationships more reliable than physical traits alone.
Reproductive Isolation and Speciation
- Reproductive isolation occurs when members of different populations can no longer mate successfully, leading to the emergence of new species.
Examples and Modern Classification
- Genetic similarities among species are often more accurate than physical similarities due to shared ancestry.
- For instance, the giant panda's classification based on physical traits initially placed it with raccoons, but genetic studies reveal it is more closely related to bears.
