Introduction Flashcards
chemotherapy medication used to treat a number of types of cancer
Paclitaxel (PTX)
the study of organism identification, classification, and nomenclature
Taxonomy
7 major themes of biology
- Evolution leading to unity and diversity
- Hierarchy of Organization and Emergent Properties
- Cellular Basis of Life
- Heritable Information
- Correlation of Structure and Function
- Homeostasis
- Interaction of Organisms and their Environment
System in systematics
- position in the tree of life
- system of classification
Scientific name of tomato
Solanum lycopersicum
relationship between all the organisms on Earth that have descended from a common ancestor, whether they are extinct or extant
Phylogeny
the devising or choosing of names for things, especially in a science or other discipline
nomenclature
- method of hypothesizing relationships among organisms
- method of reconstructing evolutionary trees.
Cladistics
Difference between cladistics and phylogeny
cladistics - methods by which branching patterns are generated
phylogeny - interpretation of such diagrams as historical patterns
share a similar embryonic origin
homologous structures
- convergent evolution
- have similar function
analogous structures
homologous structures
same structure, different functions
analogous structures
different structure, same functions
note presence or absence
cladistics
- aka numerical taxonomy
- attempts to group species into higher taxa based on overall similarity, usually in morphology or other observable traits, and regardless of their phylogeny or evolutionary relationships
phenetics
