Distinctive Characteristics of taxon.pptx

A General Biology lesson for Stem Learners

1. Distinctive Characteristics of a Specific Taxon

2. Definition of terms: Taxonomy Is the science of classifying organisms to conduct internationally shared classification systems with each organism placed into more and more inclusive groupings. Hierarchical system - It is an organization from a larger to smaller, or more specific categories of an organism.

3. Why do biologist use a classification system? - To name organisms and group them in a logical manner and to study the diversity of life.

4. Definition of terms: Taxon - refers to name of an organism in each level. Ex. D ogs like animals are in order carnivora. Carnivora - it is the name of the taxon at the order level. Canidae - it is the taxon at the family level. Subspecies - Members of the same species that are capable of mating and reproducing viable offspring.

5. Levels of Classification

6. Car0lus Linnaeus (18 th century) Father of taxonomy He was the scientist who first proposed organizing the known species of organisms into a hierarchical taxonomy. In hierarchical taxonomy, species that are most similar to each other were put together within a grouping. ( Genus)

7. Ernest Haekel Introduced the tree of with three kingdoms: Animalia, Plantae and Protista He made a groundbreaking discovery in evolutionary biology. He observed that isolated population evolve differently as a result of mutation and natural selection.

8. Family A group of similar genera ( plural- genus) that are put together. The species that are grouped within genera, genera are grouped within families, families are grouped within orders until such time that specific specie was then named.

9. Ex. Taxonomic hierarchy of Domestic dogs

10. Binomial nomenclature Refers to an organism that are only by its genus and species which is a two-word scientific name. Each specie has a unique binomial nomenclature to allow for proper identification.

11. Ex. Taxonomic hierarchy of Human Being

12. Importance of Taxonomy in Biology To identify taxonomic group showing how living things relate to one another. To classify a group organism with shared characteristics Facilitates communication between researchers conducting similar studies
