Emergent Biological Hierarchy
- The whole > sum of all parts
- Ex: Memories = emergent properties of nerve networks
Reductionism
- Sum of parts > whole
- reducing complex system into smaller easier parts
- ex: Studying DNA to understand inheritance
Systems biology
- 1) components working together
- 2) any level of organization is a system
- 3) tries to model behavior from interaction of parts
- 4) predicts how a change in one affects other part or the whole system
- 5) answers large scale questions
Levels of Organization
- Biosphere > Ecosystem > Community
- >Population > Organisms> Organs and systems >Tissues > Cells > ORganelles >Molecules

Structure & Function....

correlated at all levels
Negative feedback
- accumulation of end product(output) slows the process
- ex: sugar broken down to make ATP, excess ATP inhibits more breaking down
Positive feedback
- product(output) speeds up production
- ex: Blood clotting: damaged blood vessels > platelets
Taxonomy
- names and clasifies species
- uses shared characteristics to make order
Domains of lyfe
- Bacteria (prokaryotic)
- Archaea (prokaryotic)
- Eukarya (eukaryotic)
Eukarya kingdoms
- 1) Plantae (photosynthesis)
- 2) Fungi (absorption)
- 3) Animalia
- *distinguished by mode of nutrition
Natural Selection
- Descent with modification
- Common ancestors
Types of Data
- Qualitative
- QUantative
