What is the act of putting organisms into different slots called?
The act of putting organisms into different slots is classification.
Classification allows us to do the following:
1. It allows us to put find the commonalities in different organisms and to manage our knowledge of the immensely diverse life forms, present and past.
The commonality finding helps us to study a few and then draw general conclusions about the class.(It is not possible to study each and every organism on Earth.)
Classification has helped us go beyond superficial similarities and understand patterns e.g. whales are not fish and bats are not birds.
Classification, using modern molecular biology tools has helped to underpin, with greater firmness the theory of evolution.
Human health has benefited from classification as it helped us to exploit antibiotic producing organisms.
