Evolution

Group of organisms capable of breeding to produce living, fertile offspring.

• Used to name species in two parts:
•   genus - generic name
•   species - specific name

Process of naming and organising organisms into groups based on their characteristics.

The analysis of molecular differences in different organisms to determine their extent of evolutionary relatedness.

So that organisms find other members of the same species to produce fertile offspring.

• Sexual selection
• Recognition of own species
• Pair bond
• Synchronise mating

The taxonomical classification of organisms in successive levels of complexity from Kingdom to Species.

The variety of living organisms.

• Ecosystem diversity - range of different habitats
• Species diversity - number of different species + individuals in a community
• Genetic diversity - genetic variation, number of alleles in gene pool

• Co-extinction - 
• Over-exploitation - 
• Invasion of alien species -
• Habitat loss/fragmentation -
