- Classification
- Taxonomic groups
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- First word = genus
- Species
- Second word = species
- Why?
- To identify species
- To predict characteristics
- To find evolutionary links
- Taxonomic groups
- Kingdoms
- 5 kigdoms
- Prokaryotae
- Protoctista
- Fungi
- Plantae
- Animalia
- Domains
- Eukarya
- 80s ribosomes
- 12 proteins
- Archaea
- 70s ribosomes
- 8-10 proteins
- Bacteria
- 70s ribosomes
- 5 proteins
- Eukarya
- 5 kigdoms
- Phylogeny
- Evolutionary relationships
- Common ancestor
- Closer branches = closer e. relationshjip
- Continuous tree
- Evidence for evolution
- Palaeontology
- Fossils
- Layers of rock
- Bacteria at bottom
- Simplest life form evolved
- Vertebrates at top
- Simplest life form evolved
- Sequence matches ecological links
- Common ancestor
- Allow relationships between living & extinct
- Fossils
- Comparative anatomy
- Homologous structure
- Same underlying structure
- Vertebrate limbs
- Same underlying structure
- Divergent Evolution
- Homologous structure
- Comparative biochemistry
- Proteins & rRNA
- Look at molecular sequence
- Amino acid sequence
- Order of DNA bases
- Amino acid sequence
- Differences v. neutral base pair substitutions
- Find common ancestor
- Palaeontology
- Variation
- Interspecific
- Differences between organisms different species
- Intraspecific
- Genetic
- Alleles
- Mutations
- Meiosis
- Sexual reproduction
- Chance
- Environmental
- May affect plants to a greater degree
- E.g. getting sunlight
- Representing graphically
- Standard deviation
- Correlation coefficient
- Students t-test
- Interspecific
- Adaptations
- Anatomical
- Body coverings
- Teeth
- Camouflage
- mimicry
- Behavioural
- Survival behaviours
- Courtship
- Seasonal behaviours
- Migration
- Hibernation
- Innate
- Learned
- Physiological
- Poison production
- Antibiotic production
- Water holding
- Convergent evolution
- Analogous structures
- Anatomical
- Changing
- Natural selection
- Variation
- = Differences
- Best adapted
- Increased chance of surving
- Pass allele
- with advantageous characteristic
- Repeated
- Peppered moths
- Sheep blowflies
- Variation
- Natural selection
- Classification
