Wild Cards- Some animals still fit into classification though they do not follow all the rules example with mammals they give live birth. echidna and platypus lay eggs and are mammals but they they still are is because they have fur. Penguins are birds and have feathers but can't fly just like the ostrich and emu so they still fit into being classified as birds.
Size differences because a rat and a whale are both mammals but a rat is oh so smaller than a whale.
Location- Where the animals live a chinchilla and a polar bear live far far away from each other and are still mammals.
Taxonomists
Cell
Species
By using relative age. Over a long period of time, sediment will, layer by layer, coat and cover the fossil, making it difficult for paleontologists and scientists to figure out how old the fossil really is.
The 2 main groups animals are classified by are vertebrate (has a backbone/spine) and Invertebrate ( without a backbone/spine). Then animals are broken up into other groups such as Reptiles, Birds, Mammals, Insects, Arachnids, Fish, Amphibians, and many more. Animals are classified so that we can identify them. Scientists and Paleontologists can often tell which group an animal is in depending on their bones.In fact, even us humans are classified by groups! We are obviously vertebrate because we have a backbone/spine. Humans are also mammals because of the different qualities we have.
Living organisms are classified into groups to be easier to name, identify, and organize.
Taxonomists
Scientists identify organisms by taxonomy. It is a way in which organisms are scientifically named by species and sorted out by classification.

To identify organisms and determine how groups are related.
to now how they know the animals that they already identified
DNA barcoding is a tool used to identify organisms that have already been classified by taxonomists. This technique involves comparing a short, standardized gene sequence from an organism's DNA to a reference database to determine its species. DNA barcoding can help quickly and accurately identify organisms, especially when traditional morphological characteristics are not sufficient.
i recommend you use your science text book!
Scientists use dichotomous keys as a tool to help identify unknown organisms based on their characteristics. The key presents a series of paired statements about the organism's features, with the scientist choosing the statement that best matches the organism they are trying to identify. By following the key and making choices based on the characteristics observed, scientists can narrow down the potential identity of the organism.
Scientists in a lab use selective media and differential media to identify or isolate organisms. Selective media allows only certain types of organisms to grow.
It's important for scientists to be able to remove DNA from an organism because it'll help scientists identify genetic disorders or diseases.
