What is the binomial system?
Organisms are identified by 2 names.
2 of 16
What is the generic name?

What is artificial classification?
It divides organisms according to differences that are useful at the time, including colour and size.

What is natural classification?
It is based on evolutionary relationships between organisms and their anscestors. It classifies species into groups using shared features derived from their anscestors, and arranges groups into a hierarchy.

What are relationships in a natural classification based on?
Homologous characteristics - similar evolutionary origins regardless of function.
