Taxonomists usually use a set of criteria that have to do with reproduction. So even if two species can reproduce an offspring, taxonomists usually make the distinction that the offspring must be able to reproduce as well. If this is the case, then they are likely to consider the two organisms as one species.
animal classifiers classify animals... its their job
i think it's similarities because that's how scientist classify them
Over 2000 years ago, a Greek scientist named Aristrotle(AIR uh staht ul) was one of the first people to classify living things.
Scientists use a classification system to identify animals and plants. They classify them by a Kingdom, Phylum, Class, etc.
Scientist classify plants as producers due their ability to make their own food. They are in the autotrophic level of the nutrient cycle.
