what changes in methods of animal classification? How the methods of animal classification changed over time?
Answers
Firstly only types of individuals are identifying. Animals and plants and two groups are formed which classes are called the animalea and plantae.
After some time some new features are identified some living things are not like a plant and now related with animals so these things are placed in a separate group which is called the fungi.
The kingdom monera and kingdom algae are named later after studied of different features in them.
The kingdom monera is based upon the prokaryotic and eukaryotic cell.
Kingdom algae are based upon their photosynthetic and dimorphic in nature.
So these are many changes occur by time to time and living things divide into five major kingdoms.

Aristotle classify the animals according to the criteria like body size,habit and Habitats. further, as per the new developments in Sciences, references where change and thereby the criteria of animal classification too.Besides Aristotle artificial method of classification given by Aristotle was followed by Theophrastus, Pliny, John Ray, Linnaeus etc. Later 'natural system of classification ' was followed. It was based on various criteria like body organization, types of cells, chromosomes, bio chemical properties etc. The system of classification based on evolution was also brought into practise . It was used by dobzhansky and Meyer . Recently Carl Woese has also proposed the animal classification.
