Study Notes
Definition and Scope
- Systematic biology, also known as systematics, is the study of the diversity of life on Earth.
- It involves the identification, classification, and naming of organisms.
- Systematic biology encompasses the study of evolutionary relationships among organisms.
History
- Systematic biology has its roots in ancient Greece, with Aristotle's work on classification.
- Carolus Linnaeus (1707-1778) is considered the father of taxonomy, developing the modern system of binomial nomenclature.
Key Concepts
- Phylogeny: the study of evolutionary relationships among organisms.
- Taxonomy: the classification and naming of organisms.
- Systematics: the study of the relationships among organisms, including their evolutionary history.
Methods
- Morphology: the study of the shape and structure of organisms.
- Anatomy: the study of the internal structure of organisms.
- Molecular systematics: the use of molecular data (e.g., DNA, proteins) to infer evolutionary relationships.
Applications
- Conservation biology: understanding the diversity of life informs conservation efforts.
- Forensic science: systematic biology is used in forensic analysis, e.g., identifying species from trace evidence.
- Agriculture: understanding the relationships among crop species informs breeding programs.
Subfields
- Botany: the study of plant diversity and evolution.
- Zoology: the study of animal diversity and evolution.
- Microbiology: the study of microbial diversity and evolution.
