Organisms (Unity and diversity)
- Variation and species
- No two individuals identical
- Linnaeus: shared traits
- Binomial: Genus species
- Biological species concept
- Breed, fertile offspring
- Fossils, separated populations
- Gradual speciation: arbitrary
- Chromosomes
- Humans 46, chimps 48
- Diploid: even number
- Karyogram: length, centromere, bands
- Chromosome 2 fusion
- Genomes
- All genetic information
- SNPs within species
- Size not equal complexity
- Whole genome sequencing
- Faster, cheaper
- Evolutionary relationships
- Personalised medicine
