What to Focus On
- Known and described species: 1.7 to 1.8 million
- Each different kind of organism represents a species
- Biodiversity refers to the number and types of organisms on earth
- Nomenclature means standardised naming of living organisms
- Identification means correctly recognising and describing the organism
- Scientific names are universal and unique
- Binomial name has two components: genus and specific epithet
- Binomial nomenclature was given by Carolus Linnaeus
- Biological names are generally Latin and italicised
Common Mistakes to Avoid
Scientific names can be written in any style as long as the organism is identified correctly.
The genus is the second word and the species is the first word in a scientific name.
